Route & General Observations

Toured from the parking lot at Johnson Pass TH to approx 2000 feet, remaining below the ridge just above treeline.

Red Flags
Red flags are simple visual clues that are a sign of potential avalanche danger. Please record any sign of red flags below.
Observer Comments

Shooting cracks were observed (10 feet at most) at the 2000 foot elevation.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.
Weather

Cloud cover was generally broken skies with occasional obscured intervals. Temps were -4.5 C at 2000 feet... light winds out of the NE. No precip. Snow was being transported at ridgetops.

Snow surface

There was a crust to approx 1200 feet, which was then replaced by decomposing new snow, which became wind effected at 2000 feet.

Snowpack

We dug a series of 6 pits at 1650 feet on a western aspect (30 degree slope). They revealed generally good structure with an interface approx 25 cm down that yielded high strength, low energy. We dug again at 2000 feet in a wind-loaded convexity: these revealed fair structure (12-25 cm windslab over weaker snow), easy shears with resistant planar Fx character. ECT's did not reveal any propagation.
