The areas from 5500' to 8000' had a VERY supportable rock hard crust that was 4-5" thick (the ski skaggs and track lugs barley left a mark in the snow). These elevations were saturated with rain and warmed well above freezing from Feb 10-14th. I noticed a slide broke during the storm cycle Feb 7-9th when the elevation zone received 1-4' of new snow. Once it rained the following week the pictured slide occurred under the heavy loading of the rain and saturated snow. We rode in the area Monday Feb 17th after everything had finally frozen through and it was sierra cement riding conditions to say the least, even the warming of the day into the 40's did not soften the pack much at any elevation below 8k. Above 8k we had 3-6" of dense, soft, creamy snow to make turning conditions enjoyable.
