Snow-covered Forked Butte scoria cone in the center of the photo rises above the valley floor across from Bear Butte on the NE. A lava flow that was emplaced about 6,500 years ago can be seen down the left flank of the cone, one of two lobes that split around either side of Sugar Pine Ridge to the far left.
