The Cascade Range is an arc of volcanoes that extends from southwestern British Columbia to northern California. One of the six major composite volcanoes (formed by alternating layers of extruded lava and compacted ash) is Mount Baker in northern Washington. Close to the Canadian border, Mount Baker is about 85 miles north-northeast of Seattle and 65 miles southeast of Vancouver, British Columbia. This beautiful, snow-capped peak dominates the skyline from Bellingham, Washington to Vancouver, and offers multiple recreational opportunities to visitors and locals alike. The life-threatening and destructive hazards of composite volcanoes include their tephra (ejected ash and rocks), lava flows, lahars (a mudslide composed of volcanic ash and debris saturated with water, often from glacial melt), and debris avalanches. Modern Mount Baker itself is a relatively young volcano (10,000-30,000 years old), but no eruptions have been observed since the mid-1800s. However, a steam plume is often observed from Sherman Crater at the summit (10,778 feet), occasionally alarming local residents. A marked increase in plume activity accompanied by unusual snowmelt led to the temporary closure of Baker Lake by the National Park Service in 1975. These two photographs were taken from the International Space Station. The high-resolution image provides details of the rough terrain near the summit and on the upper flanks.
