Fryingpan Glacier
Fryingpan Glacier is on the east central slope of Mount Rainier. There are two stories for the origin of the name; one that some campers lost a frying pan in the creek or two, that the glacier itself is shaped like a frying pan. F. G. Plummer calls this glacier Urania to honor the Urania Society of New York. (Reese, 2009)

With the exception of data in 1981, all values here are calculated estimates based on work by Driedger and Kennard (1986), which calculates glacier volumes with the following equations:

If Glacier Length (L) > 8,500 ft:


If Glacier Length (L) < 8,500 ft:


Basal shear stress (τ) is calculated as:


Where V is the calculated volume of the glacier (ft3), A is the calculated area of the glacier (ft2), ρ is the density of ice (1.779 slug/ft3), g is the acceleration of gravity (32.178 ft/s2), and α is the average slope of the glacier.

If you need a really good research project, recalculating the glacier volumes at Mount Rainier is the way to go!
