 Later in its geological history, Kamiak Butte became part of a mountain range which was eventually nearly engulfed by the Cenozoic lava 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.
