During a cooler and wetter period from 1950 to 1979, the glacier advanced 1,476 ft (450 m) but between 1980 and 2006 retreated back 1,509 ft (460 m). Situated on the north slopes of Mount Baker, Mazama Glacier is bordered by the Park Glacier to the south and Rainbow Glacier to the east.

Mazama Glacier was named for the Mazamas, a mountaineering organization based in Portland, Oregon.
