Sandalee Glacier is in North Cascades National Park and Lake Chelan National Recreation Area in the U.S. state of Washington, on the north and east slopes of McGregor Mountain.[2] Sandalee Glacier originates in several cirques and extends from 7,800 to 6,800 ft (2,400 to 2,100 m) above sea level across a distance of almost 1.5 mi (2.4 km). In 1993, the Sandalee Glacier had an area of 2 km2.[3] The National Park Service is currently studying Sandalee Glacier as part of their glacier monitoring project.[3] Between 1993 (when monitoring began) and 2013 the glacier lost ~6 m of thickness.[4]
