Project Spotlight: San Rafael Swell - April 19-25, 2015

Photo of the San Rafael Swell, from photographer Vera de Kok,  

Spaces are available on a spring WV service project in one of the most striking areas of the Colorado Plateau - the San Rafael Swell.  Geologically referred to as a massive domal anticline (a convex fold of the earth), the Swell is marked by slot-canyons, valleys, gorges, mesas, desert streams, geologic formations and buttes.  Despite being only several hours from Salt Lake City, the San Rafael Swell offers an incredible wilderness experience with a multitude of recreation opportunities and an abundance of solitude.

The San Rafael Swell offers fascinating geologic formations, a history of ancient peoples, active wildlife and many endemic plants. Evidence of Native American cultures, including the Fremont, Paiute, and Ute, is common throughout the San Rafael Swell in the form of pictograph and petroglyph panels, many of which are accessible. The geology is so uniquely picturesque, it has served as a stand-in for alien worlds in many Hollywood productions, such as Star Trek  and Galaxy Quest. Unique geological conditions in combination with the arid climate have created microhabitats that support more than 40 rare and endemic plant species. Many of these plants are federally listed as endangered, such as the San Rafael cactus (Pediocactus despainii), Ute ladies-tresses (Spiranthes diluvialis), Barneby's reed-mustard (Schoencrambe barnebyi), and many more.

Our project will focus on a non-native plant that is abundant across the western US - the invasive and destructive tamarisk (tamarix). Tamarisk disrupts the structure and stability of native plant communities and degrades native wildlife habitat in extremely sensitive southwestern riparian areas by outcompeting and replacing native plant species (such as Cottonwoods and Willows), salinizing soils, monopolizing limited water, and increasing the frequency, intensity and effect of fires and floods. Tamarisk, as well as the other woody invasive plant common in the southwest, Russian olive, are nasty non-native plants that need to be removed to help restore wildlife habitat.

We'll camp by our vehicles at a remote site in the Sids Mountain Wilderness Study Area, picked out by our agency partners out of the BLM office in Price, Utah. From there we'll make daily hikes to work sites and explore the vast and wild San Rafael Swell. Learn more and come join us on a spring service project adventure in this remarkable place! And don't fret too much if the April dates don't line up with your calendar - we have a fall trip in the San Rafael Swell as well.

WV Visits King Range NCA on California's Lost Coast

In late April, a Wilderness Volunteers group trekked on an 8 mile backpack to a beachside campsite deep into the rugged Lost Coast of Northern California.  The Lost Coast is the longest stretch of undeveloped coastline in California. 68,000 acres are managed as the King Range Conservation Area by the Bureau of Land Management. The terrain is extremely rugged and the area experiences relatively frequent earthquakes due to the nearby Mendocino Triple Junction - the meeting of three tectonic plates just offshore.  Home to lush forests of Douglas-fir, Coastal Redwoods and Tanoaks, the area supports abundant wildlife including endangered coho and chinook salmon, steelhead trout and spotted owls.

This was WV's inaugural service project with the King Range National Conservation Area. Participants worked on trail maintenance, including building new sections of trail and water crossings, as well as removing beach debris.

By all accounts the trip was successful! We received these kind words last week from Gary Pritchard-Peterson, the manager at King Range NCA.
We're very grateful for all the participants' hard work and are really looking forward to returning to the area next year!

My First WV Project

While I’ve come to get the know Wilderness Volunteers very well over the last half year as the organization’s first Development Coordinator, it wasn’t until the recent service project in America's newest national park, Pinnacles, that I got to experience WV in the field. It was a truly wonderful experience getting out into the wild to give something back as well as meeting a terrific group of dedicated volunteers and park personnel.

The WV group at Machete Ridge in Pinnacles NP
We arrived to the Pinnacles campground on the east side of Pinnacles on a warm Sunday afternoon after a lovely drive down highway 25, known as Airline Highway supposedly because pilots used the highway as a marker on the route from LA to San Francisco. The highway has beautiful rolling hills as it parallels the San Andreas Fault, which figures into how Pinnacles came to be. The exposed rocks of Pinnacles' peaks differ from these surrounding foothills, as it is part of the remains of a massive ancient volcano that was active 23 million years ago. As part of the Pacific Ring of Fire, the volcano was 15 miles long and nearly 8,000 feet high.  Surprisingly, the volcano was located nearly 200 miles to the southeast, just north of where LA is today. Due to the earth's tectonic plates colliding and shifting, the volcano was split and two-thirds of the remains have been pushed north to where it lies now.  As the plates moved, the mass sank and erosion has carved the impressive spires that are the Park's most recognizable feature. Surprisingly, the rocks continue to move towards San Francisco at the rate of a quarter of an inch per year.
Hard to believe these rocks made a 200 mile journey to get here.
After we all arrived and set up camp, the group began to get to know each other over our first fabulous meal prepared by Carleton Sheppard. Wonderful meals would become a regular occurrence during our week at Pinnacles thanks to Carleton.  The other half of our leader team, Bill Sheppard, then gave us a brief intro on what to expect for our first workday the following morning, when we would meet with the NPS staff.

After a hearty breakfast, we were introduced to the park by NPS staff Brent, Lucy and Esperanza, who gave a great overview of the Park's features, history, conservation management goals and potential hazards to be aware of during our time in the backcountry. We were then given leather work gloves, counters, hiking poles and snake chaps as we set out to begin our week hunting for invasive plants throughout the park. Lucy and Esperanza would be our guides for the week and we began by searching from the Bear Gulch area back to campground for invasive Italian Thistle.  We scoured hillsides and walked along a wide seasonal creek bed filled with native poppies. After lunch we spread out to scour through a section of forest until one of our volunteers, John, found the mother load of thistle. We all joined together in an approx. 40' x 40' area to pull thousands of this invasive weed that has been choking out native species.

Tuesday was our free day, since there was a meeting that required attention from NPS staff and we split into groups to climb into the heart of the park via the High Peaks Trail, sadly leaving behind one of our compatriots at camp who was feeling under the weather. Despite leaving at different times and taking slightly different routes, our group met up at the Scouts Peak lookout that offered views to the west of the Salinas Valley and the Santa Lucia Mountains that lie run along the coast. We then climbed the steep and narrow section of the trail, which was exhilarating!  Yet another fabulous lunch was followed by nice views of the Balconies section of the park and then venturing down Condor Gulch trail, which gave terrific views of the rocky crags and spires. Tuesday also was the first time for confirmed sightings of one of the park's other claims to fame - home to the endangered California Condor.

   

Wednesday morning was the coldest of the week, reaching just above freezing.  While the cool nights
There's invasive mustard under there.
generally offered a nice respite to the hot and dry 90 degree days, this was a very chilly morning. We warmed ourselves by a nice morning fire before taking off on one of the longer hikes of our time in the park. Departing from the Old Pinnacles trailhead, we walked north of the high peaks we had climbed the day before, along the relatively level Chalone Creek - named after the indigenous people who lived in the area. All week long we saw many beautiful birds and butterflies, and this day was no exception. After reaching the entrance for the West side of the park, we went off-trail to attack the other invasive plant we would hunt during our time at Pinnacles - invasive mustard.  We found many mustard plants, some right as they were flowering, preventing the plants from reaching the bolting stage. All the while, we had terrific views of Machete Ridge. After successfully removing several thousand mustard plants, we trekked back to the eastside of the park, passing through Balconies Cave. The caves in Pinnacles are another fun feature of the Park.  They are above-ground Talus caves, formed by falling boulders and rocks trapped in steep canyons.  The caves are partially closed to protect the bat populations that make their home there and are fully closed to the public during breeding season.

Thursday was a fascinating day as we were introduced to Alacia Welch, one of the Park's Condor Biologists. Alacia led us to areas of the Park normally closed to the public.  We ventured up a steep road to a ridge where we would continue our hunt for invasive plants. Working along steep terrain, we were treated to views that few visitors to Pinnacles see.  We also watched a young condor perch in a tree nearby the NPS facility and then watched as it took flight over our heads. Their wingspan is seriously impressive. We asked Alacia every question we could think of, and weren't able to stump her. We toured the condor facility and saw how they trap and release birds, and monitor the birds through one-way mirrors.
Alacia answered every question we could think of.
The California Condor was very nearly extinct due to poaching, lead poisoning and habitat destruction - with only a population of 22 in the wild in the 80s. A controversial captive breeding program began in 1987 by the government and continues to this day. Pinnacles is an important site for monitoring the health of the population, with other important sites in Southern California, Baja and Arizona.  Those original 22 birds were given numbers #1-22 and tagged with monitors. The population has now reached more than 400, with more than 200 living in the wild.  

We also assisted Alacia by moving brush to cover exposed water lines that had recently been installed by the facility. We then continued to hunt for invasive plants and took an adventurous off-trail route down the mountain and back to the campsite.
Our group covered the line behind this way neat condor facility
Friday was our last work day, but it proved to have some of the most impressive scenery of our time at Pinnacles.  We began by traveling through the Bear Gulch caves and reaching the bear Gulch Reservoir - a man-made reservoir to be used in case of fire protection. We then ventured off-trail into backcountry canyons, searching for more invasive plants, finding both thistle and mustard, as well as hundreds of butterflies, birds and a snake or two.


My first WV service project was an absolute blast. By my estimates we pulled more than 10,000 invasive plants, covered over 30 miles of hiking and saw a terrific array of flora and fauna. My biggest takeaway, however, was how wonderful all the participants were! Our leaders, Bill and Carleton, were fantastic and kept us safe and well fed. All the volunteers were lovely folks, had a wonderful attitude and really embodied the spirit of giving something back.  I can't wait for my next WV trip!

Project Spotlight: Mojave National Preserve

Today we spotlight the WV project in the vast Mojave National Preserve, the 3rd largest unit of the National Park System in the contiguous US. Formerly named the East Mojave National Scenic Area and managed by the Bureau of Land Management, these striking 1.6 million acres were established as a preserve on Halloween in 1994 by the California Desert Protection Act, including a 695,000 acre wilderness area. Nestled between highways 15 and 40, the area offers many, many fascinating features and so much to explore. Towering mountain ranges present “sky island” forests of pinyon pine and white fir over great mesas, dry river beds and low-lying deserts featuring impressive sand dunes and beautiful Joshua tree forests.

An intriguing human history is here to explore alongside unbelievable geological and ecological fascinations. Notable features include the Kelso Dunes, the Marl Mountains and the Cima Dome, which features the largest and densest stand of Joshua trees in the world. Striking volcanic formations such as Hole-in-the-Wall and the Cinder Cone Lava Beds speak to the incredible geology.  2.5 billion year old rocks have been found on the Clark Mountains.

More recent human history can be seen in the preserve’s ghost towns, abandoned mines and the Kelso depot, now part of the visitor center.  Prior to European contact, Mojave tribes such as the Chemehuevi, lived in the mountains and along the Colorado river eating prickly pear, mesquite and roasted agave blooms and hunting deer and bighorn sheep.

Despite appearing as a relatively barren landscape, the area is teeming with varied and interesting animal life including many species endemic to region or otherwise rarely found outside of the preserve. One such example is the Mojave Fringe-toed Lizard (Uma scoparia), which is specialized in its ability to "swim" under sand.

Birds, reptiles, rodents, and larger mammals all reside in the area, although where you might find them varies due to temperature, time of day and elevation. A large percentage of desert animals are nocturnal, or active at night, including desert rodents, bats, owls, mountain lion, skunks, and foxes. Other animals in the Mojave are crepuscular, active at dawn and dusk.

The low regions of the Preserve are arid, with creosote bushes dominating the landscape on over 70% of the Preserve, while the mountains offer varied environments with cooler temperatures.  The service project we’ll be working on will be critical in removing invasive species of Russian thistle at the key moment before they go to seed. We will use a hula hoe, a tool specifically designed for removing thistle. We’ll camp at a comfy developed campsite with running water in the mountains which will serve as a prime location for the project as well as offering plenty of interesting options for us to explore in our free time.

Trip Spotlight: Alta Toquima Wilderness


Below is the first installment of what we expect will be a regular weekly feature of the WV blog – a spotlight on one of the many amazing wilderness areas where Wilderness Volunters will host a project in the next year. We plan to add a bit of insight into the unique features of the land where our projects occur and why we should all treasure what our wilderness areas provide. 
~~~





WV has many new service projects in 2013 and one we’re really thrilled about is in the Alta Toquima Wilderness in Central Nevada. The 35,860 acres of the Alta Toquima Wilderness officially became part of the now over 109 million acre National Wilderness Preservation System in 1989 and is managed by the National Forest Service as part of the Humboldt-Toyiabe National Forest’s 6.3 million acres, the largest national forest in the lower 48 states.
Even amongst the grandeur and beauty of the rest of the Humboldt-Toyiabe National Forest, the Alta-Toquima Wilderness stands out as a unique and significant area for our attention. The Toquima Mountain Range includes the massive and intriguing Mount Jefferson reaching just shy of 12,000 feet. The mountain offers terrific recreation opportunities with three summits, all connected over eight miles, with overwhelming biodiversity and plentiful fresh streams that support an incredible array of wildlife, including the nearly endangered sage grouse, native trout, bighorn sheep and many more.
The mountain offers more than hiking and has piqued scientific and human interest for a long, long time. The Wilderness area takes its name of Alta Toquima from the currently highest known native village in North America. In 1978, Dr. David Thomas of the American Museum of Natural History in New York surveyed the long abandoned site, ultimately disproving many archaeologists who believed that early American hunters avoided high altitude environments as too harsh and barren to sustain life. The survey and excavations at Alta Toquima proved that from 2500 BC to 0 AD, the mountains were used intermittently by small groups of hunters who seasonally exploited mountain sheep and permanent villages were constructed after that, around 1 AD. These new large, long-term settlements at Alta Toquima represented a major shift in how ancient Americans used mountain resources, and illustrate how archaeological research continues to teach us about the past.

A century prior to that discovery, this mountain range was the catalyst for a different scientific revelation.  John Muir summited Mt. Jefferson on August 17th, 1877, noting its striking qualities and confirming the theory that the Great Basin was indeed carved of glaciers:
“…while making the ascent of Mount Jefferson, the dominating mountain of the Toquima Range,  I discovered an exceedingly interesting group of moraines, cañons with V-shaped cross sections, wide névé amphitheatres, moutonnéed rocks, glacier meadows, and one glacial lake, all as fresh and telling as if the glaciers to which they belonged had scarcely vanished.
….This is a very marked and imposing mountain, attracting the eye from a great distance. It presents a smooth and gently curved outline against the sky, as viewed from the plains, and is whitened by patches of enduring snow.”
-John Muir, Eureka, NV, 1878, The Writings of John Muir, vol. 8

The mountain still maintains significant scientific interest today, recently becoming designated as a Research Natural Area by the forest service given its extreme conditions and opportunity for the study of alpine plants and wildlife.
Indeed, the Alta Toquima Wilderness offers a great deal of exciting history, knowledge and beauty.  The Wilderness Volunteers service project there will allow you to visit, experience and enjoy this amazing land while giving something back.  We’ll camp at the lovely Pine Creek campground and work on the trails to provide access to the higher elevations, plus we’ll have an opportunity to explore and play in our free time.  Learn more and sign up for the WV service project in the Alta Toquima Wilderness.
