The forested area extending across the middle of the photo is a series of lava flows erupted from the low Brushy Butte shield volcano between Medicine Lake and Lassen volcanoes. In this view from Little Hot Springs Valley to the NW, Soldier Mountain is the prominent peak in the background, Brushy Butte forms a barely detectable topographic high on the center horizon, and flat-topped Timbered Crater is an older Pleistocene crater near the rifht margin of the photo.
