Red Flags Comment
<p>We stayed in sheltered mid elevation terrain. The primary red flag is the HST which has settled from &gt;30 to about 26 to 28". In general on lower angle terrain &lt;35 degrees everything felt stable. However towards the end of the day we dug a pit and performed quick ECTs and columns on steeper rollovers. We were not able to isolate the new snow on slopes &gt;37-38 or so degrees. all failed near base of new snow. I think this may be related to the surface hoar I observed on Friday before the storm. I assumed that the warm wind may have broken it down but now I am not so sure. I would not want to be in steep terrain based on this. keeping the hazard at considerable.</p> <p>One ECTP, see below in profile notes.</p>

In general a good early season snowpack. HS - 54".

Basal facets are rounding and 3 finger hardness. Not a big concern in this area.

A rain crust about 12-14 above the basal rounding facets. It is decomposing.

The rest of the pack grades from 2 to 4 finger hardness capped by fist. One rain crust was observed in the mid pack about 12-14" above the basal facets. This appears to be decomposing. The recent storm snow has grapuel at the base.

Note ECTP 21, Q2 @ base of new snow, slow it did not "pop". This shear is similar to some of my pole columns yesterday.

Overall I would say considerable hazard we felt that we would not want to ski steep terrain.

Instability Comment
<p>See notes above for red flags.</p> <p>Considerable hazard.</p> <p>As usual for the Tushers, all of the alpine looked nuked.</p> <p>I would speculate considerable hazard.</p>

Powder, 'nuff said.  Settled out a bit from yesterday.
