[3] The glacier is just east of the Continental Divide. Arapaho Glacier is the largest glacier in the state of Colorado and helps provide water for the city of Boulder, Colorado.
Unlike the Laurentide Ice Sheet, which may have taken as many as eleven thousand years to fully melt, [3] the Cordilleran ice sheet melted very quickly, probably in four thousand years or less. [4] This rapid melting caused floods such as the overflow of Lake Missoula and shaped the topography of the fertile Inland Empire of Eastern Washington. [5]
The National Snow and Ice Data Center (NSIDC) is a United States information and referral center in support of polar and cryospheric research.NSIDC archives and distributes digital and analog snow and ice data and also maintains information about snow cover, avalanches, glaciers, ice sheets, freshwater ice, sea ice, ground ice, permafrost, atmospheric ice, paleoglaciology, and ice cores.
The Juneau Icefield Research Program also has studied the mass balance of the Lemon Creek Glacier since 1953. The glacier has had an average annual balance of −0.44 m per year from 1953 to 2006, resulting in a mean loss of over 27 m of ice thickness. This loss has been confirmed by laser altimetry. [21]

[68] [69] [70] At its peak, the Laurentide Ice Sheet reached 3.2 km in height around Keewatin Dome and about 1.7-2.1 km along the Plains divide. [71] In addition to the large Cordilleran Ice Sheet in Canada and Montana, alpine glaciers advanced and (in some locations) ice caps covered much of the Rocky and Sierra Nevada Mountains further south ...
