More detailed information about the snowpack: 

Toured 2500' up the North Face of Crater Crest yesterday from 5:00 PM - 7:00 PM. There were 2-3" of fresh snow on top of a melt-freeze crust at the base of Crater Crest near Twin Lakes. Fresh snow depth increased to 4-5" as we climbed up a north-facing gully. We observed signs of wind-affected snow throughout the tour including wind scoured surfaces and wind-loading. Above 9000' the snow felt hollow; a dense layer (1-3" thick) of wind-affected snow sat on top of low-density fresh snow. We turned around at 9400' to avoid potential wind-slab issues higher up the mountain.  During our tour winds were calm to light and temperatures were well below freezing. We only observed minor cracking in the semi-protected gully, but the cracking may be more pronounced higher up the mountain in more wind-exposed terrain.
