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

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.

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.
