      Reaching an elevation of 10,781 feet (3,286 m),  Mt. Baker dominates   
      the landscape of northern Washington. This view, towards the WSW from   
      near  Lake Ann, shows two of the more than 15 named glaciers that   
      descend in a radial pattern around the volcano: the  Park Glacier on   
      the right; and  Boulder Glacier on the left.   
       Mt. Baker, a  stratovolcano, erupted  andesite and  dacite   
      lavas from as far back as 140,000 years ago, but its most active period   
      occurred between 25,000-12,000 years ago. It was during this time that   
      it built its base and summit cone. Since then, it’s only erupted ash,   
      although a collapse of one of its flanks occurred some 6700 years ago.   
      Multiple small events took place during the 1800s and an increase in   
      gas emissions in 1975 suggested the presence of new magma in the   
      volcano. These emissions have tapered off through time.   
      The  USGS maintains an active monitoring program at Mt. Baker.   
      Because of the extensive glaciers, even small eruptions can trigger   
      devastating  lahars (volcanic mudflows), which can flow great   
      distances away from the volcano. Photo taken on August 22, 2022.
