Mount Adams (Washington)

About

Mount Adams is a stratovolcano located in the Cascade Range of Washington, United States. Standing at 12,276 ft (3, 742 m) feet, it is the second-highest mountain in Washington and a prominent feature within the Cascade Volcanic Arc, which formed as a result of the subduction of the Juan de Fuca Plate beneath the North American Plate. Adams is near two more-frequently erupting neighbors, Mount St Helens and Mount Rainier. It has twelve named glaciers descending its slopes. Geologically, Mount Adams first formed in the Pleistocene. Its construction involved multiple eruptive phases, the first around 500,000 years ago, followed by the development of the modern cone around 10,000 years ago. The last known lava flow was approximately 1,000 years ago. The volcano has the potential for future hazards, including lahars, pyroclastic flows, and ashfall. Its deeply eroded flanks drain into major regional rivers like the Cispus, Klickitat and Lewis Rivers. The mountain is home to diverse ecological zones, ranging from dense lower-elevation forests dominated by Douglas fir and western hemlock on its western slopes to drier ponderosa pine forests on its eastern slopes. These ecosystems support a rich array of flora and fauna, including large mammals like Roosevelt elk and black-tailed deer, as well as a variety of bird species and abundant wildflowers in the summer months.
