It is one of several glaciers in the park monitored to track how glacial retreat alters stream flow. Its ice sits at about 2,214 metres, with Mount Grinnell rising roughly 1.7 km to the southwest.

Swiftcurrent Glacier sits on the east side of the Garden Wall, the Continental Divide arête, at about 2,214 metres, roughly 1.7 km from Mount Grinnell. It is one of several glaciers monitored to track how glacial retreat alters stream flow. Its slow retreat makes it a useful comparison with faster-shrinking ice elsewhere in the park.

Swiftcurrent Glacier sits at about 2,214 metres on the east side of the Garden Wall, roughly 1.7 km from Mount Grinnell, which rises to 2,686 metres. It is one of several glaciers monitored to track how retreat alters stream flow, yet its own retreat has been comparatively slow: 55 acres in 2005, 14 percent less than in 1966.
