Erosional channels lead away from Crater Glacier, Mount St. Helens
Detailed Description
Crater Glacier, located inside the crater of Mount St. Helens, continues to move at an average rate of about 11 cm per day (4.3 inches). During warm weather months, meltwater creates erosional channels on the crater floor. Pictured at the center bottom of the image are newly carved (over the last two years) seasonal channels 2-4 m (6-13 ft) deep that funnel water to the Loowit Canyon. View to the west.
