The glacier is situated in a cirque to the northeast of Mount Logan. Just east of the Continental Divide, Logan Glacier is northwest of Red Eagle Glacier.[3] Estimated in 2005 to cover an area of {{convert|75|acre|km2}}, Logan Glacier covered almost {{convert|125|acre|km2}} in 1966, a reduction in area of 40 percent in about 40 years.[2] Comparing images of the glacier taken in 1914 with those from 2009, indicates that the glacier has experienced extensive retreat.[4] See also
