Siyeh Glacier is in Glacier National Park in the U.S. state of Montana. The glacier lies in a deep cirque to the north of Mount Siyeh at an elevation between 7,200 feet (2,200 m) and 6,800 feet (2,100 m) above sea level.[3] Siyeh Glacier covers an area of less than 10 acres (0.040 km2) and does not meet the threshold of 25 acres (0.10 km2) often cited as being the minimum size to qualify as an active glacier. Siyeh Glacier has experienced massive retreat, losing over 73 percent of its surface area between 1966 and 2005.[2]
