Date of Observation: 12/30/2021
Name: jeff banks

Zone: Southeast Mountains
Route Description: SW Slopes BTL

Observed avalanche activity: No
Avalanches:
Weather: S1 limited Visibility
Winds increasing to Moderate at NTL ridgetop. Some massive drifts 2m & blown out slopes with only ~50cm vs 130cm avg depth

Very Supportive midpack with ~4-5″ of low density snow overnight.

Easy trail breaking with fast skiing on top of the big storm slab.

Red Lady skin track

CB Avalanche CenterCBAC Observations

Date of Observation: 12/29/2021
Name: Ben Pritchett

Zone: Southeast Mountains
Route Description: Red Lady skin track

Observed avalanche activity: Yes
Avalanches: Saw one fresh D2-2.5 avalanche below the flat ridge section. This was adjacent to, but lower down the ridge than the skier triggered one from Dec 25. There was a ski track on the ridge nearby, so skiers might have triggered this feature from above. The crown was 2-3′ deep and took out a few trees in a short run of only a couple hundred feet.
Weather: Ridgeline Wind Speed: 10-20 mph
Ridgeline Wind Direction: W
Wind Loading: Light
Temperature: 20 F
Sky Cover: Obscured
Depth of Total Snow: 150 cm
Weather Description: Steady light snow most of the day. We experienced a brief lull in snowfall around mid-day, but it picked back up in the afternoon. Cloudy, poor visibility.
Snowpack: Travelled on southerly slopes and experienced no collapsing or cracking. The snowpack was around 140cm deep near the bottom of the mountain, with the December snow resting on mostly dirt and a few scattered crusts. Mid-mountain I measured around 150-160cm of snowpack, mostly resting on a stout crust capping percolation tubes and large facets.

rumble…Rumble…RUMBLE….Toil & Trouble

CB Avalanche CenterCBAC Observations

Date of Observation: 12/29/2021
Name: Jeff Danger Banks

Zone: Southeast Mountains
Route Description: <30º 9,300-10,000 Flat wetlands w/ willows, SW-S Aspens & bushy fields

Observed avalanche activity: No
Avalanches:
Weather: Some light snow showers and Light to Moderate winds in the afternoon.
Blizzard conditions kicked up by 4PM, got nasty real quick.
Snowpack: 1 Rumble on 5º SE facing slope @ 9,300
Triggered by Skier 1 skinning off the margin of 2m wind slab, with 4 skiers still on the big slab. Skier 1 moved off the edge of the slab into snow 90cm deep and hit the landmine (covered bush)

No other signs of instability on SW-S and traipsing through aspens, wetlands of willows.

Mellow in the Yellow

CB Avalanche CenterCBAC Observations

Date of Observation: 12/29/2021
Name: Andrew Breibart

Zone: Southeast Mountains
Route Description: Washington Gulch TH to SW slopes.

Observed avalanche activity: No
Avalanches:
Weather: Overcast with light wind to no wind. Intermittent S-1 with no snow accumulation.
Snowpack: No cracking; no collapsing; and no whomping on SW terrain below tree line on new skin track. 48 hour snow accumulation may be around 8 inches. The wind did a number to the road within the 48 hour period 1/27/21. On Monday, the road was benched. Today, it sloped into the natural hillslope

Snodgrass big collapses on ESE/SE fold in the terrain & S

CB Avalanche CenterCBAC Observations

Date of Observation: 12/28/2021
Name: jeff banks

Zone: Southeast Mountains
Route Description: Low angle open Meadows on snodgrass

Observed avalanche activity: No
Snowpack: 2 booming collapses on ESE & S @ ~9,800

Very hard to predict where we would get collapses… the usual suspects around willows didn’t produce. Collapses were in dry buried bushy terrain, snow depth ~80cm-1meter. ~9,800ft

Name: Turner Petersen

Zone: Southeast Mountains
Route Description: Seen from Brush creek road.

Observed avalanche activity: Yes
Avalanches: Large natural on what must be a 50-100 year path on the south face of Mt. CB. Looks like slide stared near the top of the large v of dense trees above country club couloir. Ran all the way into the dense aspens above the upper loop.
Weather: Storming.

Gothic weather

CB Avalanche CenterCBAC Observations

Date of Observation: 12/28/2021
Name: billy barr

Zone: Southeast Mountains
Route Description: Gothic

Observed avalanche activity: No
Weather: More of the same, though for a little while Sunday afternoon there was a ‘normal’ light snow and at under 7% water content. But late afternoon the wind kicked back up and was strong and steady all night with generally light snow, stopping around 5 a.m. The 24 hour totals are 7″ new (4½” overnight) and water 0.61″ (0.42″ overnight) and the snowpack is at 43″. About 90-95% of the time if the Gothic area gets wind, we get a decreased amount of snowfall, and this is the case now. Currently it is not snowing but obscured cloud cover and steady wind, 7-10 W gusting to 35. High was just 21F but low was a mild 13 and current 14F. Walked through drifts chest high getting to my solar panels this morning and there is a lot of wind loading once again. It is like building a brick wall but each layer leans out a little bit further each course so eventually it will fall over. billy
