Camped at Crater Lake and had an overnight hail storm. Woke up the next morning to low-lying clouds and poor snow. Crevasses were very small. Made it up and over, descending Apache's SE slopes for the sake of making good time.
We did a full carry over of our gear. Camped at Mirror Lake the previous night and started a 5:40 a.m. returned to the Brainard Lake trail head at 7:00p p.m.
We descended via the Isabel glacier's south branch, down climbing the first 100 vertical feet on plastic ice then glissaded to a point just above the turn off from the route.
This route will give you the "full on mountaineering experience"
