Avalanches:

CBMR 11,150′ N aspect cross loaded feature from SE winds below large cliff band. AE-SS-R1-D2-O. Propagated 175′

Weather: Increasing high clouds throughout the day high temp of 34 with calm winds.

Snowpack: HS 43 with approx. two inches of settlement today. In sheltered areas snow weak and faceted with specific ares of wind stiffened snow. Previously unaffected area from skier traffic or explosives.

Subject: No hate from the Slate
Aspect: North East
Elevation: 11,400

Avalanches:

There were signs of Avalanche activity on the lower slopes and rollovers , similar to what what was posted in an OB yesterday . Not much on the upper slopes .

Weather: Grey Bird Day calm and warm

Snowpack: In the zone we were in the slopes were not terribly affected by wind. Snow was dense and supportive. I did not seem this area received as much snow on the last cycle as the Kebler Pass Corridor.

Subject: Check in on Coney’s skier triggered avalanche
Aspect: North East, East
Elevation: 9,800 to 10,800ft

Avalanches:

SS-ASr-R1-D2-O. 1/9

Weather: Calm winds. Partly cloudy sky and warm feeling temps

Snowpack: HS in the 100-120 range on average. Ski pen around 20cm and SH on much of the snow surface. A few large collapses in the terrain but no shooting cracks.

The 1/9 remote triggered avalanche failed just below the holiday slab on 1.5mm NSF. This layer of NSF was about 5cm thick. Crown hight Varied between 1 to 4 feet thick. The thicker part of the slab was on a wind-loaded terrain feature. Slope angles on the bed surface were in the 34 to 36 range. East facing aspect at 10,360ft.

No Gully Washers but many D1-D2+ avalanches Below, Near and Above Tree line on Gothic’s East side including 1 that ran during the tour. See pictures.

Weather: Sunscreen re-application day, calm winds, temps warming above freezing.

Snowpack: Generally ~ 30cm new snow, surface remaining dry in the shade and becoming wet in the sun.

Aspect: North, North East, East
Elevation: 9,500-10,800

Avalanches:

Ooo boy. This is going to be long.

The highlights: One bounce, producing a collapse, that remote triggered 1 x D2, 1 x D1.5, and slumped the snow off a another rock outcrop. Two other separate collapse each remote triggered a D2 and separate D1 at the same time. The furthest point from a human triggered collapse to the furthest point of a crown, measured on google earth, was about 2,200ft. Yea baby.

2 x SS-ASr-R1-D2-O, NE, BTL
1 x SS-ASr-R1-D2-O, E, BTL
4 x SS-ASr-R1-D1.5-O, NE, BTL

1 x SS-N-R1-D1.5-I, South, ATL. Fresh Natural today. Steep rocky terrain.

There were many more natural avalanches to D2.5 in size from the 1/6 cycle. Mainly on N to E facing aspects at BTL elevations. Other aspects and elevations had a few old Persistent Slabs, but most avalanches looked to have failed within the storm snow and were often confined to gully features or wind-loaded terrain. 

Weather: High clouds hung around for much of the day. Calm wind. Warm temps.

Snowpack: The holiday slab is the slab… while the January 6th storm just added the load to tip the balance. The 1/6 storm snow was about 10 to 12″ in sheltered terrain at the elevations traveled. The 1/6 snow was very soft on NE and becoming moist on E, and other sunny slopes. The very weak NSF below the holiday slab was the layer of concern. This layer was failing in collapses and triggered avalanches, and those avalanches were either running at the interface or gouging to the ground. Boot pen to hip and ski pen about 25cm. HS in the 100-120cm range.

Collapses that produced human triggered avalanches were very very quiet and subtle. No shooting cracks where ever observed from the same area I got a collapses that remote triggered and avalanche. After a collapses, it was a long 10sec before remote triggered avalanches started running.

Avalanches:

Remote trigger on a southeast steep slope on the north end of Coney’s. Crown was up to 3-4 ft in wind loaded area. Occurred on the new snow from this week. There weren’t any signs of instability prior to seeing this avalanche.
