Siyeh Glacier
Encyclopedia
Siyeh Glacier is located in the U.S. state
of Montana
in Glacier National Park. The glacier lies in a deep cirque
to the north of Mount Siyeh
at an elevation between 7200 feet (2,194.6 m) and 6800 feet (2,072.6 m) above sea level. The glacier covers an area of less than 10 acre (0.0404686 km²) and does not meet the threshold of 25 acre (0.1011715 km²) often cited as being the minimum size to qualify as an active glacier. Siyeh Glacier has experienced massive retreat and lost over 73 percent of its surface area between 1966 and 2005.
