I outlined the glacial extent from the Mount Baker USGS topographic map.
The glacial ice extent on the map is from aerials taken in the 1980s. This point in time coincides with the end period of glacial ice advance on Mount Baker glaciers that ended in the 1980s.
Since the 1980s the glacial ice has retreated steadily back and is now even further back than the previous retreat that ended in the 1950s.

More recent retreat can be seen in a Google earth view from 2013 and more retreat has been measured over the past two years.
