Location: Paradise Divide Area
Date of Observation: 03/10/2019
Name: Eric Murrow

Subject: Views down the Ruby’s and test in Paradise Divide
Aspect: North, North East, East, South East, South, South West, West, North West
Elevation: 9,500′ – 11,000′

Avalanches:

Viewed lots of old crown from the 3/6-3/8 date range-most activity looked to have happened during peak precip. Most crowns were filled back in pretty well. Activity was largely in near and above treeline terrain with relatively few in protected terrain. A couple of D3’s but nothing historically impressive noted. Got a tangent view of Baxter Basin and it looks to be the largest slide in the area. Avalanches failed around the compass in the area near and above treeline. Few Wind Slabs noted that failed in the past day or two, but not that many.

Weather: Partly cloudy skies with strong solar, light winds with some moderate gusting, no transport observed during PM while out.

Snowpack: Dug a couple of holes on sunny and shady slopes below in treeline elevation band. No notable stability test, just ECTN very near surface. We only tested new old/interface, nothing deeper. Settled storm depths in this snow favored area were around 90-110cm snow with about half being 1F hard. Of note – the crust at the 2/28 interface on sunny slopes was incredibly smooth and slick – prying on the block after standardized test would get the meter slab to pop right out. The 2/28 crust did not appear to be collapsible as it was sitting on dense snow with minimal faceting directly beneath or above. Basal snow on sunny slopes still looks ugly with 3mm rounding DH that is F+ to 4F hard. HS on shaded, protected terrain was 300-315cm deep.

During the day strong solar was able to produce roller balls on southerly slopes up through the near treeline elevation band originating from warm rocky areas. Wet activity entrained no mass. By 5pm snow surfaces began to refreeze. Crusts were 2-3cm thick with a few cm’s of moist snow still below.
