Barely noticeable in the background is the Black Rapids Glacier. I've read that glaciers sometimes will "gallop" and advance very quickly for a short period of time. This glacier was called the Galloping Glacier in 1936-1937 when it advanced down into the valley to within 1/2 mile of the Richardson Highway. It moved forward about three miles in three months! Since it's predicted that these types of glaciers do this in 60 year cycles they are expecting it to go again sometime soon. I thought all of our glaciers were melting away!
