Beta Pass



As the glacier continued to retreat about another half mile to the northwest (left to right on photo), Beta Pass was opened, and lowered the level of Lake Watts about another 10 feet. This view of Beta Pass was photographed from the conveniently located US 19 bridge over US 422 (right on the divide at Beta Pass), looking west. Drainage was from behind and flowed away from the viewer. Note that there are two low spots in this pass, one to the right (north) through which US 422 passes, and the other just to the left of the leftmost solitary tree.
