The rocks of the study areas consist mostly of Tertiary basalt, andesite, and lahar with minor amounts of rhyolitic ash-flow tuff, rhyolite, and dacite. The rim provides good exposure of the thick sequences of volcanic rocks that underlie the wilderness study area. Dry Valley Rim is a 17-mi (5.2 m)-long north-south-trending fault block that is situated 1,500 ft (457 m) above the Smoke Creek Desert to the east. The ridges bound the Wendel and Spencer basins, an area of bleached and silicified rocks. The Skedaddle Wilderness Study Area consists of two parallel ridges, the Skedaddle Mountains and the Amedee Mountains. Existing geologic maps that cover the two study areas consist of Lydon and others (I960), Bonham (1969), and Diggles and others (1986). Steep rim rock walls and talus-covered canyons are common in the eastern third of the Dry Valley Rim study area, and the western third of the Skedaddle study area, while the majority of both study areas is gradually sloping, covered only by sparse sagebrush. Access to the study areas is provided by several light-duty dirt roads and ways that join the boundary roads. The northern boundary is the Smoke Creek Ranch road, the southern boundary the Wendel road, and the western boundary the east-side Skedaddle road. The Dry Valley Rim study area is bounded on the east by the lower Smoke Creek road, the Dry Valley road, and the Pipe Springs Road. The Skedaddle study area is bounded on the east by the Skedaddle road, on the north by the Smoke Creek Road, on the south by the Wendel road, and on the west by the rim west of Wendel Canyon. The Skedaddle study area encompasses 39,420 acres and the Dry Valley Rim study area encompasses 54,480 acres of Bureau of Land Management administered public land about 25 mi east of Susanville, California. Skedaddle and Dry Valley Rim are contiguous wilderness study areas (WSA) located in the eastern part of the Modoc Plateau in Lassen County, northeastern California, and Washoe County, northwestern Nevada (fig. Geological Survey conducted a reconnaissance geochemical survey of the Skedaddle (CA-020-612) and Dry Valley Rim (CA-020-615) Wilderness Study Areas in Lassen County, California, and Washoe County, Nevada. Traveling in groups is always a good idea, as well as informing someone of where you will be going.In the summer of 1985, the U.S. Travel with warm clothing, first aid, food, water and appropriate tools to fix a problem. Other InformationĪlways plan ahead and prepare for uncertainty. The entire valley is managed by the Bureau of Land Management. Trails often run alongside private properties and utilities. Remember to go over, not around, obstacles on designated routes to avoid unnecessarily widening the trail. Please do your part to keep Dry Valley open by staying on the designated trails in the area. ![]() Remember to close all gates after passing through. Do not feed wildlife, as this habituates wildlife to humans and alters natural behaviors. Please observe all wildlife from a safe distance. Wild Horses, burros, and cattle can be encountered in the Dry Valley area at any time of year. Trails will have signage designating acceptable use depending on width and terrain. There are a variety of trail difficulties and trail terrain varies from flat and sandy, to high desert sagebrush, to steep lava rock canyons. The Dry Valley OHV area trails are open for multi-use and is frequented by hikers, bikers and equestrians, keep an eye out and be respectful of other recreators. Here there are amenities such as graveled entrances, restrooms, picnic areas, and visitor information. Staging is available at two trailheads - Turn of the Road Trailhead and Mission Wells Trailhead. Extensive road networks provide many potential loop trails. Dispersed camping is allowed, no ADA accessibility. The Dry Valley Off-Highway Vehicle Area covers over 73 square miles (46,813 acres) in central Washoe County, about 75 miles north of Reno on U.S. ![]()
