South Irving glacier

South Irving was an east facing small glacier (never officially named and lumped with Irving yet a separate ice mass and thus a separate glacier) on the south side of Middle Sister that is now a stagnant ice mass. It recently stagnated, potentially in response to the low snow year and hot summer of 2015. The crevasses in the photos below are due to collapse of a sub-ice cavern, not due to ice flow.
