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.
