Oregon Public Broadcasting’s venerable Oregon Field Guide series kicks off it’s 25th season in October with a remarkable story on the hidden network of glacier caves that have formed under the Sandy Glacier, high on Mount Hood’s west flank.

In the video preview (below), Oregon Field Guide executive producer Steve Amen says that “in the 25 years we’ve been doing Oregon Field Guide, this is the biggest geologic story that we have ever done”. This is bold statement from a program that has confronted all manner of danger in documenting Oregon’s secret places!

Glacier caves are formed by melt water seeping through glaciers and flowing along the bedrock beneath glaciers. Over time, intricate networks of braided tunnels can form. Because a glacier is, by definition, a river of moving ice, exploring a glacier cave is inherently dangerous — and this is what makes the upcoming Oregon Field Guide special so ambitious.

Cave explorers have been actively exploring and mapping the extent of the Sandy Glacier caves for the past three years. This previously unknown network of caves has been dubbed the Snow Dragon Glacier Cave System by cavers Eduardo Cartaya, Scott Linn and Brent McGregor in July 2011. Cavers have since surveyed (to date) well over a mile of caves in the network, with parts of the cave system nearly 1,000 feet deep.

Ice Cave or Glacier Cave? Here in volcano country, it’s worth noting that a glacier cave is different than an ice cave. Where a glacier cave has roof of glacial ice, an ice cave occurs where persistent ice forms inside an underground, rock cave. In the Pacific Northwest, we have several examples where ice has accumulated inside lava tubes to form true ice caves, such as the Guler Ice Cave near Mount Adams and Sawyer’s Ice Cave in Central Oregon.

To date, the Snow Dragon cave network consists of three caves that intersect, dubbed the Snow Dragon, Frozen Minotaur, and Pure Imagination caves. Within these caves explorers have discovered a fantastic landscape of streams and waterfalls flowing under a massive, sculpted ceiling of ice.

The caves are punctuated by moulins (pronounced “MOO-lawn”), or vertical shafts in the ice formed by meltwater. Some of these moulins are dry, some are still flowing, and a few have have grown to become skylights large enough serve as entry points into the cave system for daring explorers.

Caving expeditions to the Sandy Glacier caves by the National Speleological Society (NSS) in 2011 and 2012 were featured in the February 2013 NSS News, with a dramatic photo of colossal moulin on its cover. These volunteer expeditions included NSS geologists, glaciologists, spelunkers, scuba divers and mountain climbers who spent eight days documenting the cave system from a base camp high atop the Sandy Glacier.

According to the NSS explorers, the Snow Dragon cave complex is the largest ice cave complex in the lower forty-eight states, and one of the largest in the world. To date, these explorers have found icy passages ranging from huge, ballroom-sized open spaces with 40-foot ceilings to narrow, flooded crawl sapces only a few feet high, and passable only with diving gear.

The Oregon High Desert Grotto, an affiliate of the NSS, has posted a series of fascinating maps documenting their explorations on their website.

The Story Behind the Sandy Glacier Caves?

Glacier caves typically form near the snout of a glacier, and explorers simply follow the outflow stream into the cave system. Such was the case with Paradise Ice Caves at Mount Rainier (now disappeared) at the terminus of the Paradise Glacier. More recently, hikers have explored the outflow opening at the Sandy Glacier, as well.

The Snow Dragon caves under the Sandy Glacier are different, however. While the glacier does have an outflow opening to the cave system, the cave network extends far beyond the terminus of the glacier, apparently reaching almost to the headwall, nearly a mile away and almost 2,500 feet above the terminus in elevation. The scale and scope of these caves seems to be partly the result of the glacier shrinking, and not just the effects of melting near the terminus of the glacier.

This broader phenomenon first became apparent when a huge moulin — known informally to many hikers as the “glory hole” and formally named the Cerberus Moulin by cavers — appeared in the glacier a few years ago. The Cerberus Moulin is plainly visible to hikers from nearby McNeil Point, which also serves as the jump-off point for explorers.

The following photos of the Sandy Glacier were taken nine years apart, in 2003 and 2012, and show the startling retreat of the glacier over just the past decade. The Cerberus Moulin had not yet formed in the 2003 photo, but is plainly visible in the 2012 image. For reference, the broad moraine to the left of the Cerberus Moulin is labeled as (A) in the photos:

Sandy Glacier in 2003

Sandy Glacier in 2012

The photo comparison shows big changes in the activity of the glacier, too. What was once an icefall near the terminus of the glacier (B) in 2003 has since receded to the point that the rock outcrop that was beneath (and formed) the icefall is now exposed in the 2012 image. Likewise, the lower third of the glacier (C) was clearly crevassed and actively moving in the 2003 image compared to the 2012 image, where an absence of crevasses shows little glacial movement occurring today in this section of the glacier.

The rapidly shrinking glacier could be an explanation for the relative stability and remarkable extent of the caves underneath the ice. The increased melting is sending more runoff through and under the glacier, helping to form new moulins feeding into the ice caves.

The slowing movement of the lower portion of the glacier could also help explain why the cave network has become so extensive, as more actively flowing ice would be more likely to destroy fragile ice caves before they could become so extensive and interconnected.

Part of a Larger Story

The Sandy Glacier Caves discovery is really part of the much larger story of Mount Hood’s rapidly shrinking glaciers. After millennia of relative stability, we are witnessing broader changes to the landscape surrounding in response to the retreat of the glacial ice.

The downstream effects in recent years from Mount Hood’s melting glaciers have been startling, and the Sandy Glacier is no exception. Sometime during the winter of 2002-03, a massive debris flow was unleashed from just below the terminus of the Sandy Glacier, and roared down the Muddy Fork canyon. The wall of mud and rock swept away whole forests in its wake, burying a quarter mile-wide swath in as much as fifty feet of debris.

The view downstream (below) from the center of the debris flow shows the scope of the destruction, with the debris at least 50 feet deep in this spot where the Timberline Trail crosses the Muddy Fork.

The Muddy Fork has only recently carved its way down through the 2002-03 debris to the original valley floor, revealing mummified stumps from the old forest and visible giving scale to the scope of the event (below).

Seven years after the 2002-03 flow, the Muddy Fork had cut a channel down to its original elevation, revealing the full depth of the flow.

With no way to know how long Mount Hood’s glaciers will continue to retreat, catastrophic events of this kind will recur in the coming decades. Runoff from the retreating glaciers will continue to carve away at newly exposed terrain once covered by ice, with periodic debris flows occurring as routine events.

In November 2006, another major flood event in the Sandy River canyon caused damage even further downstream, in the Brightwood area, where private homes line the Sandy River:

Damage from the 2006 flood was still being repaired when yet another major storm burst stormed down the valley in January 2011. During this event, a large section of Lolo Pass road briefly becoming part of the Sandy River, and scores of homes were cut off from emergency responders:

The 2011 event washed out the south approach to the Old Maid Flat Bridge over the Sandy River, forcing the Forest Service to jury-rig a temporary ramp to the bridge. The entire crossing has since been replaced, but like all repairs to streamside roads around the mountain, there is no reason to assume that another event won’t eventually destroy the new bridge, too.

Similar events have occurred over the past several years on the White River, Ladd Creek, East Fork Hood River and the Middle Fork Hood River. The predicted climate changes driving these events give every indication that we will continue to watch similar dramatic changes unfold around Mount Hood in decades to come.

Just as the wildfires that burned through forests on the eastern and northern flanks of Mount Hood over the past few years have given us new insights into the cycle of forest renewal, the unfolding geological events linked to changing glaciers provide a similar opportunity to better understand these natural processes, too.

While these destructive events are tragic to our sentimental eyes, the rebirth of a forest ecosystem is truly remarkable to witness — as is the discovery of the Sandy Glacier ice caves in the midst of the larger decline of Mount Hood’s glaciers. All of these sweeping events are reminders that we’re just temporary spectators to ancient natural forces forever at work in shaping “our” mountain and its astoundingly complex ecosystems.

So, stay tuned and enjoy, this show is to be continued!

In the small world department, I had the honor of meeting epic caver, climber and photographer extraordinaire Brent McGregor on the Timberline Trail this afternoon. He and caving partner Eric Guth had spent the night near the entrance to the Snow Dragon Glacier Cave!

After learning a LOT more about the Snow Dragon cave complex from Brent today (and having my jaw drop repeatedly as I heard about their exploits under the glacier!), I’ve updated the above article — including the more accurate use of the name Cerberus Moulin in lieu of the generic “glory hole” nickname that some hikers have been using.

Brent also pointed me to a couple fascinating new videos from OPB that just add to the anticipation of the Glacier Caves premiere on OPB:

Thanks for the terrific conversation, Brent – great meeting you and Eric!

Yocum Ridge Waterfalls

March 31, 2012

Scores of little-known waterfalls hide in Mount Hood’s backcountry. Some are towering glacial torrents, while others are quiet forest cascades, framed in moss and maple leaves. But when conditions are right, few rival the towering trio of waterfalls that mark peak snowmelt on the upper ramparts of Yocum Ridge.

These waterfalls are unnamed and unmapped, but familiar to hikers crossing the Muddy Fork on the Timberline Trail or visiting McNeil Point, across the canyon. They completely disappear by autumn in dry years, but in early summer, they are Mount Hood’s roaring counterparts to the famous seasonal giants of Yosemite.

(Click here for a larger view)

These waterfalls originate from an unnamed glacial cirque, or bowl, high on the northern shoulder of Yocum Ridge, the massive spine that divides the Muddy Fork from the Sandy River, and extends to the summit of Mount Hood. Though they flow from a relatively small basin, the snowfields that accumulate in the cirque each winter generate a surprisingly powerful runoff.

In recent decades, the year-round snowfields in the basin have almost disappeared, compared to 1960s-vintage USGS maps (below). This seems to have opened a more direct snowmelt channel to the waterfalls, as they seem more prominent in recent years, while the perennial stream to the west, as shown on the USGS maps, has become much less prominent.

(Click here for a larger view)

The cirque is well below the tree line, so the lack of forests in this amphitheater is also a good indicator of both heavy snow accumulations and frequent winter avalanches.

The view (below) from across the canyon shows the waterfalls in relation to Yocum Ridge and the cirque. The low ridge to the right of the falls forms a lower cusp of the cirque, and this ridge serves as a dike that channels most of the spring runoff toward the waterfalls. The Yocum Ridge Trail (shown on the map, above) terminates at the rim of the cirque, in the extreme upper right corner of this view:

A closer look at the waterfalls, as viewed from below at the Muddy Fork crossing (below), shows the rugged upper crags of Yocum Ridge in the background, with the waterfalls tumbling from the cirque into the Muddy Fork canyon. The cirque is located to the right, just outside this frame.

Surprisingly, a sizeable forest is perched on the slopes to the left of the waterfalls, apparently spared by the most frequent avalanches that have cleared most of the slopes within the cirque.

(Click here for a larger view)

It’s somewhat unknown how the streams that feed these waterfalls originate, since they are not mapped, and perhaps not even explored. However, from Google Earth imagery, the trio of waterfalls seem to flow from three distinct sources, with the western falls draining the main portion of the cirque, and the middle and east segments draining directly off the upper slopes of Yocum Ridge.

A closer view (below) shows the trio of waterfalls in detail. The westernmost of the three (on the right) is by far the largest, dropping at least 700 feet in the main cascade, and arguably nearly 800 overall. This drop is on a scale with Multnomah Falls, which drops a total of 635 feet, by comparison.

The eastern segment (on the left) is next in size, and though dwarfed by its larger sister to the west, is quite large and drops at least 500 feet. The middle segment is a tall, thin slide that is nearly as tall as the western segment, albeit much less dramatic.

The towering western falls (left) starts out as a 100-foot slide, and quickly fans out for 150 feet before leaping over a wide, 400-foot plunge.

The falls collects in a steep amphitheater at the base of the main plunge before making a final 70-foot plunge into a roiling, narrow gorge.

A closer look at the main plunge of the western falls (below) reveals the raw power at work during peak snowmelt, with its roaring curtains of falling water.

Somehow, thickets of red alder cling to the cliffs around the falls, framing the scene. This spectacle persists for several weeks in early summer, yet nearly disappears in autumn and through the winter.

The following video captures this dramatic scene, as viewed from the Muddy Fork crossing on the Timberline Trail in July 2010:

How to visit the Waterfalls

Viewing the Yocum Ridge Waterfalls up close makes for a terrific day hike, and the waterfalls are at their prime as soon as the trails open — usually late June or July. The recommended 5.4 mile (round-trip) hike shown on the map below starts at the usually crowded Top Spur Trailhead, near Lolo Pass. But most of the hikers are heading for McNeil Point, so you will see very few people beyond the series of junctions at Bald Mountain.

(Click here for a larger, printable map)

Starting at Top Spur, the trail climbs somewhat steeply for 0.4 to a signed junction with the Pacific Crest Trail (PCT). Turn right onto the PCT, and immediately reach a confusing 4-way junction with the Timberline Trail. Turn right onto the famed Timberline Trail, heading uphill and to the right, past a sign pointing to the Muddy Fork

The Timberline Trail climbs gently through noble fir forest, soon passing the unmarked junction with the Bald Mountain trail. A short distance beyond, the trail traverses across the steep meadows on the south face of Bald Mountain, with stunning views of Mount Hood and the Muddy Fork canyon.

Mount Hood and the Muddy Fork canyon from Bald Mountain

After re-entering the forest, the trail passes yet another junction, this time with the unsigned Bald Mountain Cutoff. Head straight, going through a log gate before making a very gradual descent to the Muddy Fork.

Once at the Muddy Fork, the trail enters the scene of a violent debris flow that crashed through the area in 2002, snapping thousands of mature trees like match sticks and pouring 20 feet of debris across the valley floor.

The Muddy Fork has made short work of the debris in the subsequent 10 years, cutting all the way down to its former stream level. This makes crossing difficult for Timberline Trail hikers, but that’s okay: the best view of the Yocum Ridge waterfalls is from one of the scores of boulders resting atop the debris flow, where you can relax and take in Mount Hood, the waterfalls and the roaring Muddy Fork, below.

Be sure to bring binoculars and a camera — and enjoy!

Building the Timberline Trail

November 24, 2010

The McNeil Point Shelter.

For decades, hikers and backpackers have taken Mount Hood’s famous Timberline Trail for granted — and why not? It was one of the earliest alpine hiking trails in the American West, and seems to have evolved with the mountain itself.

But the story of the trail is one of an original vision that has been realized in fits and starts, and the story is still unfolding.

The first recreational trail on Mount Hood followed the South Eliot Moraine from Cloud Cap Inn to Cooper Spur, as shown on this 1911 map.

The first modern trail on Mount Hood was established in 1885, beginning at David Rose Cooper’s tent camp hotel, located near the present-day Cloud Cap Inn. The route followed the south Eliot Moraine to his namesake Cooper Spur. Soon thereafter, the Langille family would lead hikes and climbs on this route from the new Cloud Cap Inn, completed in 1889.

The Langilles also established a route from Cloud Cap to Elk Cove for their visitors, completing another section of what would someday become the Timberline Trail.

Hikers climbing toward Cooper Spur along one of the original sections of the Timberline Trail.

The route remains a popular trail, today, though it has never been formally adopted or maintained by the Forest Service. The first leg of this trail briefly functioned as a segment of the Timberline Trail, thanks to a temporary re-routing in the mid-2000s (more about that, later).

The significance of the original Cooper Spur trail is that it was built entirely for recreational purposes, the first such route on the mountain.

Camp Blossom was built some fifty years before Timberline Lodge was opened in 1938, but established the same network of trails that have since served the lodge.

Other hiking routes soon followed on the south side of the mountain, connecting the former Camp Blossom to nearby Paradise Park and the White River canyon. Camp Blossom was built by a “Judge Blossom” in 1888 to cater to tourists. The camp was at the end of a new wagon road from Government Camp, and located near present-day Timberline Lodge. It was eventually replaced by the Timberline Cabin (1916), and later, Timberline Lodge (1938).

The informal network of alpine trails radiating from Camp Blossom in the late 1800s still forms the framework of trails we use today. This is especially true for the nearly 7 miles of trail from White River to Paradise Park, which largely defined the Timberline Trail alignment in this section.

By the 1920s, the Langille family had developed trails from their Cloud Cap Inn to nearby Elk Cove (1924 USGS map).

By the 1920s, the Mazamas and other local outdoor clubs were pushing for more recreation facilities around the mountain, and public interest in a round-the-mountain trail was growing.

By this time, new Forest Service trails had been built on the north side of the mountain from the Clear Branch valley to Elk Cove and along Vista Ridge to WyEast Basin. These trails were connected at timberline (with a spur to Dollar Lake), creating another segment of what was to become the Timberline Trail. Combined with the route from Cloud Cap to Elk Cove, nearly 8 miles of the future Timberline Trail had been built on the north side of the mountain by the 1920s.

By the 1920s, the Vista Ridge and Elk Cove trails were established, extending the emerging Timberline Trail from Cloud Cap to Eden Park (1924 USGS map).

The Timberline Trail is Born

The concept of a complete loop around the mountain finally came together in the 1930s, during the depths of the Great Depression, when Franklin Delano Roosevelt’s New Deal recovery program, and the Civilian Conservation Corps (CCC), brought the needed manpower and financial resources to the project.

The CCC completed the new 37.6 mile Timberline Trail in 1934, stitching together the existing north side and south side trails, and covering completely new terrain on the remote west and east sides of the mountain.

The venerable Cooper Spur shelter still stands on the slopes above Cloud Cap, maintained by volunteers.

The Corps built a generous tread for the time in anticipation of heavy recreation use. The new trail was built 4 feet wide in forested areas, 2 feet wide in open terrain, and gently graded for easy hiking.

The trail was marked by square cedar posts placed at rectangular intervals over open country and by blazes in forested areas. Many of the distinctive trail posts survive between Cloud Cap and Gnarl Ridge, mounted in huge cairns.

Shelters were built along the trail by the CCC crews as a place for hikers to camp and rest, and as protection against sudden storms. Most are of the same stone design, with a small fireplace and chimney. They were built with steel rafters instead of wood so that the structures, themselves, would not be used as firewood in the treeless high country, and also to withstand heavy winter snows. Of the six original stone structures, only those at McNeil Point, Cairn Basin and Cooper Spur survive (see large version of map, below).

Map of the completed Timberline Trail and CCC era shelters.

(Click here for a large map)

Three wood structures were also built along lower sections of trail, at Ramona Falls, Bald Mountain and Elk Meadows. Of the three, only the rapidly deteriorating structure at Elk Meadows survives.

The completed trail featured a couple of oddities: the McNeil Point shelter had been constructed on a high bluff above the Muddy Fork that was eventually left off the final trail alignment, due to concerns about maintaining the trail at this elevation. Today, thousands of hikers nevertheless use the partially completed trail each year to reach the historic shelter and spectacular viewpoint.

Curiously, the shelter at Elk Meadows was also built off the main loop, perhaps because at the time, the meadows were seen as much a place to graze packhorses as for their scenic value. Like McNeil Point, this “forgotten” shelter continues to be a very popular stop for hikers, today.

This 1921 map shows the Oregon Skyline Trail terminating at Mount Hood, before construction of the Timberline Trail. Note the early Bull Run Reserve encompassing the entire west side of the mountain.

By the late 1930s, much of the new Timberline Trail had also been designated as an extension of the Oregon Skyline Trail — according to maps from the time (above), the Skyline had previously terminated on the slopes of Mount Hood, above Government Camp.

The expanded Skyline Trail arrived at the Timberline Trail from the south, near Timberline Lodge, turned east and traced the new Timberline Trail counter-clockwise around the mountain before descending to Lolo Pass, then headed north to Lost Lake and the Columbia Gorge.

1970s Trail Renaissance

A third major era of trail construction on the mountain came in the 1960s and 1970s, when several major re-routes of the Timberline Trail were built.

By the early 1960s, the Oregon Skyline Trail had been relocated to the west side of the mountain, following the Timberline Trail from Timberline Lodge north to the Bald Mountain Shelter, then on to Lolo Pass.

By the time the Pacific Crest Trail was established in the 1968 National Trails Act, absorbing the old Skyline Trail, a new route across the Muddy Fork canyon was in the works for the Timberline Trail.

The Cairn Basin stone shelter is the best-preserved of the CCC-era structures, thanks to more protection from the elements than most of the original buildings.

By the early 1970s, this new section rounded Yocum Ridge from Ramona Falls, crossed both branches of the Muddy Fork, then ascended to the steep meadows of Bald Mountain, one of the most popular Timberline Trail destinations today.

The new Muddy Fork segment is now part of the Timberline Trail loop, with the Pacific Crest Trail following the old Timberline Trail/Oregon Skyline Trail alignment. Though less scenic, the old route is more direct and reliable for through hikers and horses.

In contrast, the scenic new route for the Timberline Trail has been a challenge for the Forest Service to keep open, with the Muddy Fork regularly changing channels, and avalanche chutes on the valley walls taking out sections of trail, as well.

Going, going… this view from the slowly collapsing Elk Meadows shelter will soon be a memory. This is the only remaining wood shelter of three that were built by the CCC.

In the 1970s, a section of trail descending the east wall of Zigzag Canyon was also relocated, presumably as part of meeting Pacific Crest Trail design standards. While the old route traversed open, loose slopes of sand and boulders, the new trail ducks below the tree line, descending through forest in gentle switchbacks to the Zigzag River crossing of today.

At Paradise Park, a “low route” was built below the main meadow complex, and the headwater cliffs of Rushing Water Creek. Like the Zigzag Canyon reroute, the Paradise Park bypass was presumably built to PCT standards, which among other requirements, are intended to accommodate horses.

The north side of the mountain also saw major changes in the early 1970s. The original Timberline Trail had descended from Cathedral Ridge to Eden Park, before climbing around Vista Ridge and up to WyEast Basin. The new route skips Eden Park, traveling through Cairn Basin, instead, and climbing high over the crest of Vista Ridge before dropping to WyEast Basin.

Beautiful meadow views line the “new” Vista Ridge trail section completed in the early 1970s.

Finally, a section of trail near Dollar Lake was moved upslope, shortening the hike to the lake by a few hundred yards, and creating the sweeping views to the north that hikers now enjoy from open talus slopes east of Dollar Lake. Just beyond Dollar Lake junction, the descent into Elk Cove was also rebuilt, with today’s long, single switchback replacing a total of six on the old trail which descended more sharply into the cove.

In each case, the new trail segments from the early 1970s are notable for their well-graded design and longer, gentler switchbacks. While the main intent of the trail designers was an improved Timberline Trail, the new segments also created a numerous new routes for day hikers who could follow new and old trail segments to form hiking loops. These loops are among the most popular hikes on the mountain today.

The Future?

The retreat of Mount Hood’s glaciers in recent years has destabilized the outwash canyons, and in the past two decades, massive debris flows have buried highways and scoured out streambeds. One of the oldest segments of the Timberline Trail, near Cloud Cap, has been disrupted by washouts for nearly a decade, and is now completely closed, thanks to a huge washout on the Eliot Branch in 2007.

Sign from the first re-route, posted in 2001. Now the trail is completely closed at the Eliot Branch.

The Forest Service has since struggled to find funding to reconnect the trail at the Eliot Branch. The first washout moved the stream crossing uphill, taking advantage of the original Cooper Spur path established in the 1880s, then crossing to a parallel climbers path on the north moraine of the Eliot Glacier.

This temporary crossing lasted a for a few years in the early 2000s before the massive washout in 2007 permanently erased this section of trail. This portion of the loop as since been completely closed, though hundreds of hikers each summer continue to cross this extremely unstable, very dangerous terrain.

Site of the Eliot Branch washout and closure -- and the risky route hikers are taking, anyway.

The growing volatility of the glacial streams will ultimately claim other sections of trail, creating an ongoing challenge for the Forest Service to keep the Timberline Trail open each summer.

If repairing the washouts along the trail were as costly as those along the nearby Mount Hood Loop Highway, then there might be some question of whether it makes sense to keep the trail open. After all, millions of dollars are being spent this year to rebuild the Mount Hood Highway bridge over White River, yet again, in an area that has had repeated washouts.

Hikers crossing the Eliot Branch before the 2007 washout.

By comparison, a wilderness trail is exceptionally cheap to build, and much less constrained by topographical or environmental concerns than a road. It really just comes down to money and priorities, and the Forest Service simply doesn’t have the funding to keep pace with the growing needs of the Timberline Trail. With even a modest increase in funding, the trail can be rebuilt and adapted to periodic washouts, or other natural disturbances.

Speaking Up

One way to have an impact on the funding situation for the Timberline Trail is to weigh in with your Congressman and Senators. While the current political climate says that earmarks are dead, history tells us otherwise: ask for an earmark for the Timberline Trail. After all, the trail is historic and an international draw that brings tourists from around the world to help boost local economies.

If you’re not an earmark fan, then you can argue for an across-the-board funding boost for forest trails as a job-producing priority in the federal budget. A ten-fold increase over current levels would be lost in rounding areas in the context of the massive federal budget.

Yet another angle are the health benefits that trails provide, particularly given the federal government’s newly expanded interest in public health. This is emerging as the best reason to begin investing in trails, once again.

Hikers negotiating the Muddy Fork crossing after the 2002 debris flow swept through the canyon.

Of particular interest is the fact that Oregon Congressmen Earl Blumenauer and Greg Walden actually hiked the loop, just before the 2007 Eliot Branch washout. One is a Democrat, the other Republican, so you can cover your bipartisan bases with an e-mail both! They share the mountain, with the congressional district boundary running right down the middle, so both have an interest in the Timberline Trail.

Finally, Oregon Senator Ron Wyden championed expanded wilderness for the Mount Hood area for years, and President Obama finally signed the bill into law earlier this year. So, another angle is to argue for the needed funding to support trail maintenance in these new wilderness areas, especially since they will require more costly, manual maintenance now.

It really makes a difference to weigh in, plus it feels good to advocate for trails with your Congressional delegation. Here’s a handy resource page for contacting these representatives, and the rest of the Oregon delegation:

Here’s how to send an e-mail to Congress

Thanks in advance for making your voice heard!
