Kamiak Butte is a county park located in Whitman County between the towns of Palouse and Pullman in Eastern Washington, near the border of Idaho. It is named after Chief Kamiakin of the Yakama tribe.
Most of the park's 298 acres (1.21 km2) consist of timberland on the northern slopes of Kamiak Butte. The butte itself is a steptoe, or island, of precambrian quartzite projecting approximately 1,000 feet (300 m) above the surrounding wheatfields. The reddish rocks once formed the bed of an ancient sea, and the grains of sand embedded in them can still be seen glittering in the sun. Later in its geological history, Kamiak Butte became part of a mountain range which was eventually nearly engulfed by the laval flows that covered most of Eastern Washington in a layer of basalt.
The region's intensive wheat and lentil farming has made Kamiak Butte an important haven for indigenous plant and animal species. 170 plant species, 130 bird species, and 30 mammal species have been observed inside the park.
For most visitors, the park's chief attraction is the Pine Ridge Trail, a 3.5-mile (5.6 km) loop which begins at a parking area and climbs through evergreen forestland to an exposed ridge. The trail continues along the ridge, affording spectacular views of the surrounding palouse country before dropping back into the forest. A short "summit spur" leads to the butte's highest point - a rocky promontory on the west side with an elevation of 3,641 feet (1,110 m). Camping is available all year, except during periods of drought, when it is often prohibited due to fire danger. Interpretive programs are offered in the spring and summer months; other amenities include an amphitheater, picnic tables, outdoor grills, covered shelters, restrooms, and a playground.
Kamiak Butte is a National Natural Landmark, and Pine Ridge Trail is listed as a National Recreational Trail within the National Trails system.
