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.
This two photograph was taken from the International Space Station. ISS008-E-15491 provides details of the rough terrain near the summit and on the upper flanks. This view provides a regional picture of Mount Baker, showing its proximity to Bellingham.
