Largest Glaciers in the North Cascades

This map shows the largest glaciers in the North Cascades and surrounding area (not including the Olympics and Mount Rainier) that were 1 sq. km. or greater as of 1971, identified by Austin post et al in the 1971 USGS paper titled “Inventory of glaciers in the North Cascades.” NOTE: MANY OF THESE GLACIERS ARE MUCH SMALLER TODAY, SOME SADLY SHRINKING TO NEAR NON-EXISTENCE. Thanks to John Roper for help putting together the list which orders the glaciers by size (SEE NUMBERS ON MAP). Poster by Steph Abegg, 2009-2010.
