Route Description: Mt Emmons. Redwell Tour.
Observed avalanche activity: Yes
Avalanches: A wide propagating slab on an easterly aspect into Redwell Basin. 11,600ft. D2. Avalanche debris looked soft so I’d estimate it ran yesterday during the storm.
A fresh cornice fell in redwell basin, probably ran this morning or at the end of the storm. D2.
A fresh cornice fell in the Climax Chutes, probably ran this morning or at the end of the storm. D1.5
Roller balls and some small loose wet avalanches around the solar half of the compass.
Weather: Clear sky, rising temps. Calm winds down low and light winds in the alpine.
Snowpack: At 10,800ft on the South side of Mt Emmons the recent HST was 35cm. We climbed the south side of Mt Emmons while the snow was just warming, then skied dry snow of the West and north sides. By the time we hit OBJ and changed both aspects and elevation the snow surface was wet. This tour was for good snow and avoided the avalanche problems.

Route Description: Viewed from Mt. CB
Observed avalanche activity: Yes
Avalanches: Several D2 wind slabs on Avery and Gothic that ran yesterday. Numerous small wet loose today (D1s). And of course the very large persistent slab off of Gothic, which triggered an additional persistent slab crown below the cliff band.
Weather: Clear skies, mild temps, occasional light drifting near wind exposed summits.

Avalanches: A large persistent slab (D2.5) on a shallow, east-facing slope on East Beckwith looks like it ran yesterday. Several wind slabs D1-D2, mostly yesterday, one today. A large cornice fall today (D2). Numerous small wet loose today (D1s).
Weather: Clear skies, mild temps, occasional light drifting near wind exposed summits.

Route Description: A couple of laps at Coney’s via a semi-standard route. 9,600-10,800 feet, ENE aspect.
Observed avalanche activity: Yes
Avalanches: D1 wind slab in steep, cross-loaded WSW terrain on Gothic that looked pretty fresh.
Weather: Clear and calm. Temps in the teens at 9AM, quickly climbing to tropical by 11AM.
Snowpack: 6-8″ new snow. Cold and dry at the start, but rapidly transforming to wet and sticky in a couple of hours.

Route Description: Gothic
Observed avalanche activity: Yes
Avalanches: Very large persistent slab on the east face of Gothic. Slide ran after 4 p.m. yesterday. It did not reach the county road anywhere but did hit an RMBL cabin though right at the end of a side shoot off the main run. so it looks like it may be OK. But it’s buried so who knows.

Route Description: Gothic townsite
Observed avalanche activity: No
Weather: Light to moderate snow Friday morning with light afternoon snow and steady wind with strong gusts as it remained cloudy all day. Wind slowed after dark, becoming light just before sunrise with gradual clearing after midnight. Total new 24 hour snowfall was 5½” new with water 0.38″. Snowpack reached 95½” (a record depth for March 31) and now sits at 94½” with a partly cloudy sky and just a light breeze. March ended with 102½” snowfall with water of 9.24″- 4th most snow in a March and second most water content since 1975. And just think- we were all here to shovel through it.

Zone: Northwest Mountains
Route Description: Baxter Basin area; traveled on North to East to Southeast aspects to about 11,000′.
Observed avalanche activity: Yes
Avalanches: Ski triggered a 10″ wind slab on a small test slope. Visibility was too poor to see most avalanche terrain.
Weather: Moderate to heavy snowfall. Strong, variable winds. They were initially blowing down the basin (out of the west) and then switched to blowing up the basin (out of the north). Periods of intense wind drifting.
Snowpack: Valley floor storm totals ranged from about 10″ at the Slate TH to 20″ in Poverty Gulch. In wind-sheltered terrain, the snow was fairly low density and cohesionless, and sluffed in steep terrain. The snow got noticeably thicker and denser in wind-affected terrain. Drifts were up to 3 feet thick in some areas, and other areas were scoured down to yesterday’s crust. I got a mix of shooting cracks and nothing on steep drifted features. Cracks were up to 30′ long.
Join CBAC staff and friends on Friday, April 7th at the Talk of the Town to celebrate another great season. Enjoy a free beer and music by Atmospheric Whiskey River. The party starts at 5:00 pm and the music starts at 6:00 pm.
