Subject: Anthracite Mesa-Coneys: WIND
Road leading to Trailhead, observed two areas with storm slabs.
East aspect below trees above Meridian Lakes: Two slides: SS-N-R1-D1 on a slope at least 30 degrees on a linear
West/SW aspects between lower two cattle guards: SS-N-R1-D1 on slope less than 30 degrees but below a convexity in a shallow snowpack evidenced by grasses and shrubs on slope.
Weather: Cold and blustery.
Moderate winds in the valley bottom and on the ridge. Obscured skies. Periods of S1 and S-1 snowfall.
Moderate winds on ridge didn’t transport snow onto the leeward sides. Winds in the valley bottom with no trees or vegetative cover transported snow, filling in skin track with 6 inches of snow.
Snowpack: Between 6 and 8 inches of new snow within 24 hours with a few areas favored by wind deposition of 10 inches.
All about the wind.
No collapses or cracking. Tested a few convex slopes in the valley bottom on east and west aspects with no failures or shooting cracks.
