- <p>Warming of the new snow was our main concern today. Minor cracking on steep switchbacks, no collapsing noticed. With the moderate density snow and calm winds I did not notice any wind transport of the new snow even on the 11k ridgelines durring my tour. There was a limited amount of wind damage on high west aspects. </p>
Photo 1. Looked to be a SS-As-R1-D1.5 triggered sometime early this AM on Tri Chutes.
Photo 2. Close up of that slide.
Photo 3. Natural on East aspect.
Photo 4. More activity on East
Photo 5. Loose Wet down a little lower on East.

- <p>With a few days of snow and the chance for the sun to be out today I felt that Wet Slabs would be the main concern today. There seamed to be a smooth surface under the storm snow 45cm down for them to run. Looked like a mix of graupel under there still waiting to heal. Likely in many locations that received a fair bit of snow and saw some sun. </p> <p>A few of the slides I saw seamed to be storm slabs running fairly slow but entrapping a decent amount of snow, R1 or 2, fairly small compared to the path. Still large enough to ruin your day if in consequential terrain. Looks like it is still snowing in upper lcc and noaa/ cottonwoods forecast is calling for a 80% chance of 4-8" for alta guard through 5 A.M. This could keep the storm slabs active the next 24 hours. </p>
A few inches of heavy snow at the trailhead, (7600’) transitioned to moderate density snow around 8400' on North aspects this morning. From there up it was harder to make a snowball with your hand on north aspects. ECT’s and CT’s showed failures 20cm and 45cm down from the top of the pack. Twenty cm down on a density change and also 45cm down from the start of the storm cycle.
