Glacier Monitoring

 

Glaciers are a significant resource of many mountain ranges of the world, including the three large parks in the NCCN.  Combined, the glacial resources of this network are extensive, covering 235 km2.  They are integral components of the region’s hydrologic, ecologic, and geologic systems, and they are retreating rapidly.  At NOCA, geologic mapping data and a 1998 inventory (Granshaw, 2001) indicate that glacier area has declined 44% in the last 150 years.
