When there is snow this route is a fun little jaunt. There are no real difficulties and with a bivy at Green Lake make for a nice outing.

Gain the Prouty Glacier from Green Lake. Head up the glacier to a rock band with a couloir. Climb though the rock band via the couloir. Once through the rock band continue up to gain the summit crater.

There may be a bergshrund below the rock band.


Approach from Cascade Lakes Highway and the Green Lake Trailhead to a bivy at Green Lake. From the northern end of basin turn up hill via a gully to gain the Prouty Glacier.


Crampons and and ice axe. Depending on conditions and a group's ability a rope and pickets for the bergshrund.
