LOCATION: Kebler Pass Area
DATE OF OBSERVATION: 03/28/2015
NAME: Evan Ross
SUBJECT: IRWIN TENURE AND RUBY RANGE
ASPECT: East, South, West
WEATHER: Clear, high temps at 12k 38 and 10K 50 degrees. Mostly light westerly winds through the day that where increasing to moderate around 2pm. clouds started to increase to “few” around 3pm.
SNOWPACK: Todays observations where based in the same terrain as yesterdays observations, and are highlighting the differences between the two days. Recent storm snow has seen more settlement and was much less reactive today in the form of wet loose avalanches, compared to yesterday. I didn’t notice any more natural lose wet avalanche activity in the Ruby Range on East to South facing terrain, though the possibility of skier triggering may have remained. On the terrain we skied at NTL/BTL elevations, skier triggering a loose wet avalanche had become much more stubborn then yesterday, though we continued to seek colder snow and changed aspects throughout the day as the snow heated up.
The old snow surface below last weeks storm snow remained frozen in the form of thick crusts 20-45cm thick in the terrain observed. So we where only worried about loose wet avalanches and still need more time at these warm temperatures to see melt water penetrating deeper into the snowpack and to start worrying about wet slabs.
