Spiral Butte is a cinder cone in Yakima County, Washington in the United States. The summit and most of the slopes are located within the William O. Douglas Wilderness of the Okanogan–Wenatchee National Forest between White Pass and Rimrock Lake.[2] Historically the mountain has also been referred to as Big Peak.[3] The present name stems from its orientation with a lava flow extending north out of the cone before spiraling east and then south. US 12 runs along the southern slope of the butte.[4]
