Bottom Line

Travel was from 3500' to 6600.' We toured up a low-angle ridge to the top of Lockwood Point. Above 5500', we found about 12" (30cm) of low-density snow had fallen since the beginning of the week. Above 5500' in wind-protected non-solar aspects, we found near-surface facets buried below the new snow. The new snow sitting on top of near-surface facets was not propagating in ECT's. There was no propagation because the new snow had not yet formed a slab, creating propagation propensity. I expect increased avalanche hazard and propagation in ECT's with more snow and wind in the forecast.
