Strong overnight refreeze and rapid daytime melt in Johnson Canyon.

Starting out from the trailhead, we had signs of a very strong snow surface refreeze last night, as expected. Just below 6,600' the surface melt-freeze crust was 9 inches thick and K hard at 9:40 am. By the time we had ascended to 7,420' at 10:15 am the crust had weakened to 1F hard and was no longer boot supportable but remained ski supportable. Warming air temperatures pre dawn this morning over the upper elevations appeared to have given the higher elevations a head start on surface melt today.

Descending SE and SW aspect terrain in the 10:30 to 11 am timeframe, about 1 inch of surface wet snow existed on top of ski supportable crust.

Some fractures were evident behind melting/dripping cornices. These fractures are a common sight in this climate.

Looking around on nearby peaks, older events of small sections of cornice collapse and size D1 loose wet avalanches were prevalent, most likely occurring during the rain event Monday afternoon/night (4/8-9).
