Ant, upper Yule Creek

CB Avalanche Center2015-16 Observations

Location: Paradise Divide Area
Date of Observation: 04/02/2016
Name: Evan Ross
Subject: Ant Peak, upper Yule Creek
Aspect: North East, East
Elevation: 11,000-12,600

Avalanches: saw a few old storm slabs on easterly facing slopes. Crowns looked to be around 30cm deep. These old avalanches were in the D1-1.5 range.
Weather: Clear sky, strong solar, calm winds in the alpine.
Snowpack: Toured mostly above treeline in a snow favored part of the range. Sluffing on steep northerly facing slopes and small natural loose wet avalanches on east-south-west aspects. No other avalanche problems observed. Ski pen on shaded slopes was about 25cm with the top couple inches of the snowpack faceted with little cohesion. This weaker snow at the surface created the small sluffing problem on these aspects.

11,000ft, NE aspect, 35 degree slope. March 6th interface was very small rounding faceted particles with no hardness difference from surrounding layers. Our most recent dust event was down 50cm and a CT test produced no results down to that interface. March 6th interface was down about 80cm.

11,600ft, East aspect, 28 degree slope. Moist snow surface. Nothing significantly concerning about the snowpack structure down to March 6th dusty interface. Snow surfaces on east aspects were all moist and shedding roller balls or small loose wet avalanches up to our hight point at 12,600ft
