 EPOD - a service of USRA

The Earth Science Picture of the Day (EPOD) highlights the diverse processes
and phenomena which shape our planet and our lives. EPOD will collect and
archive photos, imagery, graphics, and artwork with short explanatory
captions and links exemplifying features within the Earth system. The
community is invited to contribute digital imagery, short captions and
relevant links.


 Mt. Baker at Sunrise

   Summary Author:  Marli Miller

   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.
