It is crazy to think of just how far glaciers used to extend in Southeast Alaska. There is a reason that the entrance to each glacier arm is bordered by a bar. The bar marks the point of greatest advance of the glaciers during the last ice age.
The glaciers pushed gravel and boulders, then receded, leaving the bar behind.
