Unhappy Chutes

CBAC 2020-21 Observations

Zone: Southeast Mountains

Location: Happy Chutes, Mount Emmons

Date of Observation: 12/01/2020

Name: Zach Guy and Zach Kinler

 

Subject: Unhappy Chutes

Aspect: North East, East

Elevation: 9,000 – 10,300

Avalanches:

Intentionally triggered several long-running dry loose avalanches, large enough to drag or carry someone (D1.5). The slides entrained the entire snowpack (about a foot deep) and ran about 1000 vertical feet.

Weather: Mostly cloudy, light northerly winds, very light snowfall.

Snowpack: A shallow, weak mess. Snow depth is about a foot deep, almost entirely fist hard, 1 to 1.5 mm facets. The surface is 5 – 15 mm surface hoar (upright and intact) covered by the inch of snow that fell this morning. On east to southeast aspects, there is a decaying melt-freeze crust midpack which disappears as you tilt north. Yep, buried surface hoar on facets on a crust – nasty!
