Columbia Glacier—Unusual Glacier Cycles
Lecture no. 20 from the course: The World's Greatest Geological Wonders
Taught by Professor Michael E. Wysession | 29 min | Categories: The Great Courses Plus Online Science Course
Witness the power of glaciers, which carry a continuous stream of ice and rock from the tops of mountain ranges down to the base—often to the sea, such as at Columbia Glacier in Alaska. Chart the rapid retreat of Columbia Glacier since 1980, which has been triggered by climate change.
