Nooksack Type 1 glacier with lots of crevassing, indicating
higher velocity, and a substantial elevation range leading to
high accumulation rates. Sholes Glacier which has a moderate
slope and modest accumulation rates is a Type 2 glacier. North
Cascade glacier behaved differently this century? On Snowfield
Peak there are three glaciers Colonial, Neve and Ladder Creek
which each have behaved differently. Colonial retreated
throughout the century. Ladder Creek advanced from 1950-1975 and
Neve stopped retreating from 1955-1980. Thus, it is not simply
recent climate driven since they share the same climate setting.
We observed behavior of 38 North Cascade glaciers during the
last century to illustrate three different types of glacier
response to climate change: The initial response times (Ts) of
North Cascade glaciers to both a positive and negative mass
balance changes resulting from cl
