Location of Heritage Range in Western Antarctica.
Union Glacier (79°45′S 082°30′W / 79.750°S 82.500°WCoordinates: 79°45′S 082°30′W / 79.750°S 82.500°W), is a large, heavily-crevassed glacier which receives the flow of several tributaries and drains through the middle of the Heritage Range, Ellsworth Mountains, Antarctica. The glacier drains from the plateau at Edson Hills on the west side of the range and flows east between Pioneer Heights and Enterprise Hills. Union Glacier was mapped by U.S. Geological Survey (USGS) from surveys and U.S. Navy (USN) air photos, 1961-66. The name was applied by Advisory Committee on Antarctic Names (US-ACAN) in association with the name Heritage Range.
The glacier is the site of Union Glacier Blue-Ice Runway SCGC and Union Glacier Camp.
