Quick report
The weather was generally clear, calm and warm. More solar input than we were expecting, with the forecasted afternoon clouds mostly failing to materialize (or at least being relatively sparse). Winds were almost non-existent where we traveled, although we never made it to ridge top. Signs of warm snow we observed included frequent tree bombs, the numerous S-facing, small, ski cut avalanches as noted, quite a few rollerballs, and some point releases coming off rocks and cliffs. Additionally, we also noted some surface hoar, largest near open creeks, but also present on other open slopes.
Avalanche
Intentionally triggered numerous (10+) small avalanches via ski cut on steep slopes ranging from about 30-40 degrees facing almost due South. Interestingly, these did NOT run on the Early Feb Crust, but a layer in between. There was about 4 inches of snow atop the EFC in this location, and about two inches of that was sliding with our ski cuts. I did not have a card or loupe to get a good look at the crystals, but it seemed that there might have been some wet facets at the interface (I am not confident about this). Occasionally they stepped down (if you can call it that for a couple inches) the rest of the way to the EFC. While these avalanches were very small (only about 2 inches deep), they ran as cohesive slabs and entrained additional snow on their way down. I would describe them as touchy, extremely reactive to ski cuts. The largest ones were probably 30 ft across and ran 75+ ft downhill. D0.5 no risk of burying anyone or doing any damage. But the bigger ones definitely had the potential to push you somewhere you didn't want to go. This forced us to proceed carefully down this steep slope, methodically ski cutting to clear paths of this very reactive surface layer.
