   The Cascade Range, stretching 800 miles (1,300 km) from northern
   California, U.S.A, to southern British Columbia, Canada, separates the
   moist, green coastal plain from the dry interior landscape. The peaks
   of the Cascades are actually a volcanic chain created by the slow
   movement of dense oceanic crust as it slides beneath North America.

   The mountains contain towering volcanic peaks, many of which are
   currently considered active even though eruptions in recorded history
   have been rare. The most recent was the eruption of Mount St. Helens on
   May 18, 1980. Because of the risk that eruptions could present to human
   life and property, the United States Geological Survey (USGS) Cascades
   Volcano Observatory (CVO) monitors 10 volcanoes in the Cascades. Five
   of these are in Washington (Glacier Peak, Mount Adams, Mount Baker,
   Mount Rainier, and Mount St. Helens), while the rest are in Oregon
   (Mount Hood, Mount Jefferson, Newberry, Three Sisters, and Crater
   Lake).

   Oh June 4, 2023, the Moderate Resolution Imaging Spectroradiometer
   (MODIS) on board NASA’s Aqua satellite acquired a true-color image of
   the Cascades Range in part of the states of Washington (north) and
   Oregon (south).

   The boundary line between the states runs along the Columbia River,
   which flows from inland westward to the Pacific Ocean through a deep
   gorge through the mountains. Snow caps the tallest volcanic peaks,
   while lower elevations are green with summer vegetations. The
   snow-capped volcanoes in this image are, from north to south, Mount
   Rainier, Mount St. Helens (west), Mount Adams (east), Mount Hood, and
   Mount Jefferson. Snow also sits atop the Goat Rocks Wilderness, located
   between Mount Rainer and Mount Adams. The Goat Rocks are remnants of a
   large volcano, extinct for about two million years.
