A member of the Taku Glacier Lodge crew (near Juneau AK) sent this photo this week of Hole in the Wall. HW spills out the side of the enormous Taku Glacier, and faces the lodge directly. It also features an 'ice falls' as calves escape through the smallish opening. HW is across the Taku River a mile or two. In 1930s photos in the lodge, there is almost nothing spilling through HW's hole. This to me indicates much more than 'glacial insensitivity' but actual growth in Taku since 1930. They know the glacier has been large enough long enough to have been spilling through HW way before 1930.
