|Peak:||Mt. Aetna (13er)|
|Date of Information:||05/12/2013|
From ~11.2k to ~11.9k we had intermittent postholing on ~2 to ~5 inch crust over wet, faceted snow. We bailed out of the couloir to the ridge on climber‘s right at 11.9k. This sucked. Don‘t do it. It would be better to take the climber‘s left ridge.
There was a weak freeze the night before our hike. It got very warm on 5/12, but the couloir needs more time and more hard freezing.
There was evidence of multiple wet slides in the couloir coming from the ridge on climbers left. They were sliding on a dust layer.
We did not need snowshoes for the approach road.
