Date of Observation: 12/02/2017
Name: Ian Havlick
Subject: Upper Slate Recon
Aspect: North, North East, East, South
Elevation: 10-11,500

Avalanches:  Observed several D1 wet loose avalanches that looked a few days old, and one wet loose triggered persistent slab below steep cliffed terrain on a northeast facing slope near treeline. Observed through binoculars and did not investigated, but debris looked to have run like a wet loose, scouring to talus below.

Weather: Scuddy clouds this morning cleared to partly cloudy skies midday, occasional high clouds during the afternoon. Very warm temperatures with 46º in valley, and 41º at 11,000ft at 1500. Skiff of new snow from flurry overnight.

Snowpack: Quite low snowpack overall with dry conditions on south and west facing slopes near and below treeline. On shady north and northeast facing slopes, snowpack varied between shallow, moist, isothermal snow near and below treeline to more faceted snowpack with thickening, slick surface crusts 5-8cm thick.
