Shepard Glacier is a glacier remnant (glacieret) In Glacier National Park in the U.S. state of Montana. The glacieret is immediately southeast of Cathedral Peak.[2] Shepard Glacier was one of a number of glaciers that have been documented by the United States Geological Service (USGS) to have retreated significantly in Glacier National Park.[3] Shepard Glacier was measured in 2009 to have decreased to less than 25 acres (0.10 km2), considered to be a minimal size to qualify as being considered an active glacier.[4] Between 1966 and 2005, Shepard Glacier lost 56 percent of its surface area.[5]
Comparing the 2005 image at right to the one below taken in 1913, it is apparent that Shepard glacier has retreated significantly between these dates.
