Lyman Glacier taken from same location in 1921 and 2005.

Loss of glacier volume since 1984, represents 20-40% of entire glacier volume.

Variations in glacier ice coloration due to changes in grain size and air bubble size. The bluer ice has larger crystals.

Glacier mass balance is assessed in crevasses such as this on Easton Glacier. Note the horizontal horizon marking the 2007 summer surface with 3 .2 m of 2008 winter snowpack on top.
