The reserve falls within the Steens Mountain Cooperative Management and Protection Area (CMPA). Both the reserve and the CMPA are administered by the Bureau of Land Management. The wilderness area encompasses {{convert|170166|acre}} of the CMPA's total {{convert|428156|acre}}.[3] {{convert|98859|acre}} of the Wilderness are protected from grazing and free of cattle.[4] TopographyThe Steens Mountain Wilderness ranges in elevation from {{convert|4200|to|9733|ft}} at the summit of Steens Mountain. The reserve features a variety of vegetative zones, from the arid sagebrush zone in the Alvord Desert, through the western juniper, mountain mahogany, mountain big sagebrush, quaking aspen, subalpine meadow, and subalpine grassland, to the snow cover zone.[5] Steens Mountain is the largest fault-block mountain in North America. Pressure under the Earth's surface thrust the block upward approximately 20 million years ago, resulting in a steep eastern face with a more gentle slope on the western side of the mountain. During the Ice Age, glaciers carved several deep gorges into the peak and created depressions where Lily, Fish, and Wildhorse lakes now stand.[5] FloraVegetation in the Steens Mountain Wilderness varies greatly according to elevation. Common plants include sagebrush, juniper, various species of bunchgrass, mountain mahogany, aspen, mountain meadow knotweed, and false hellebore.[5] Other vegetation endemic to Steens Mountain includes Steens paintbrush (Castilleja pilosa var. steenensis), moss gentian (Gentiana fremontii), Steens Mountain penstemon (Penstemon davidsonii var. praeteritus), Steens Mountain thistle (Cirsium peckii), a dwarf blue lupine, and Cusick's buckwheat (Eriogonum cusickii).[6][7][8] FaunaSteens Mountain is home to a variety of wildlife, including bighorn sheep, Rocky Mountain elk, pronghorn, sage grouse, and the Great Basin redband trout. Cattle can be found in the wilderness as well, though they are excluded from grazing {{convert|98859|acre}} on top of Steens Mountain.[3][5] Coyote are also known to the area. See also
