The mountain itself is an "island," consisting of Precambrianquartzite projecting approximately 1,000 feet (300 m) above the surrounding wheat fields. 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 Cenozoiclava flows that covered most of Eastern Washington in a layer of basalt.[citation needed] Steptoe and Kamiak Buttes are outliers of Idaho's Coeur d'Alene Mountains.[3]
The region's intensive wheat and lentil farming has made Kamiak Butte an important haven for indigenous plant and animal species. Over 170 plant species, 140 bird species,[4] 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 views of the surrounding Palouse country before dropping back into the forest. A short "summit spur" leads to the mountain'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.
For ham/amateur radio operators, two linked repeaters are near the top of the mountain. The frequencies are 146.74 MHz, with a 600 kHz negative offset, a PL Tone of 100 Hz (the 2 meter repeater), and 53.75 MHz, with a 1.7 MHz negative offset, and a PL Tone of 100 Hz (the 6 meter repeater).
