Snow-covered Forked Butte cinder cone in the center of the photo rises above the valley floor across from Bear Butte on the NE.  A lava flow that was erupted about 6500 years ago can be seen descending the left flank of the cone, one of two lobes that split around either side of Sugar Pine Ridge at the extreme left.
