    Water-filled potholes

    Cauldron-like depressions called potholes are scattered around the upper reaches of the Black Rapids Glacier. They often fill with water over the summer, eventually draining on the surface or subglacially. They are left-over remnants of crevasses that formed during the 1936-1937 surge of Black Rapids. During the surge the glacier terminus advanced by about 3 miles and earned the nickname the "galloping glacier". Taken June 13, 2014.

    Becoming A Stream

    A water channel forms in the snowpack on a glacier surface. It won't be long at all before this water that is pooling in a low-lying trough will start to flow.

    Lake

    The lake known as . . . Lake. It's an ice-dammed marginal lake - where the glacier meets the mountainside. When the sub-glacial hydraulic system is ready to move the water it will drain.
