This photo of volcanic Mount Washington (at left) in the Cascades Mountain Range of Oregon was taken while on a hike in the Deschutes National Forest. I was with members of the Native Plant Society of Oregon on the Pacific Crest Trail. Mount Washington is a 7,795 ft (2,376 m) composite cone that's thought to be less than 250,000 years old (Pleistocene). It's been prominently carved by the Wisconsin glaciation, between 18,000 and 12,000 years ago. The flat topped volcano to the right is Hayrick Butte, which is referred to as a tuya.
The charred trees in the foreground are lodgepole pines (Pinus contorta), mountain hemlocks (Tsuga mertensiana), and subalpine firs (Abies lasiocarpa). They were burned in a lightning-caused wildfire that destroyed over 100,000 acres (40,469 hectares) of timber lands. Fire is an important part of this subalpine ecosystem and returns approximately every 50 to 150 years. The herbaceous groundcover is primarily species of sedges (Carex) and common beargrass (Xerophyllum tenax) a member of the Lily family. Photo taken on July 4, 2010
