Baxter Basin

CB Avalanche Center 2019-20 Observations

Location: Paradise Divide Area
Date of Observation: 03/30/2020
Name: Zach Kinler
Subject: Baxter Basin
Aspect: North, North East, East, South East, South
Elevation: 9,600-11,100
Avalanches:

2 x Wet Loose D1 East 10,000′
1 x Wet Loose D1.5 Skier-triggered SSE 11,000′

Weather: B-A-N-A-N-A-S, this weather is bananas!. Saw it all today with nothing consistent for more than half an hour at a time. Light to moderate snow showers, graupel showers, intense sunshine, a bit of green-housing after periods of sun when the wind wasn’t present, wind drifting small amounts of snow and an occasional winter-like feel when clouds snow and wind combined forces.

Snowpack: 5″ HST which settled quickly and became moist on all aspects below ~9800′. Due north stayed dry above that elevation. A few small wet loose avalanches including one skier-triggered were able to run on the previous day’s crust, which was smooth and slick.

It snowed more

Location: Kebler Pass Area
Date of Observation: 03/30/2020
Name: Steve Banks
Subject: It snowed more
Aspect: North East
Elevation: 9,000-12,000

Avalanches: None observed today

Weather: It snowed a lot more than expected. Sunny spells in the morning gave way to S3 from noon to 2 pm. Even then it kept snowing mostly S1-2 through the afternoon. Hell yea. It was cold at treeline with winds building in the afternoon from the West. Moderate blowing snow was observed from 3 pm on. When the sun popped down low it got hot quick.

Snowpack: We didn’t dig around much, but seemed to be 40-50 cms of recent snowfall since last week. Last night/today’s snow remained cold and light. Saturday snow wasn’t crusty, but dense. Much less new snow at lower elevations. No signs of instability were found on slopes up to 35 degrees.

Storm obs

Location: Kebler Pass Area
Date of Observation: 03/30/2020
Name: Eric Murrow
Subject: Storm obs
Aspect: North, North East, East, South East, South
Elevation: 9,000′ – 11,600′

Avalanches: Skier triggered two very small Wind Slabs on very open south-facing slopes behind ribs. R1D1
Observed a D1.5 Wind Slab in East Bowl in Anthracites – crown already filled in completely by 4pm.
Observed two fresh avalanches on drifted southeast-facing near treeline features in Elk Basin and Evans Basin on Emmons massif. Only got a brief view a long way off but looked D1.5ish.
Weather: Mostly cloudy skies with a low ceiling obscuring alpine terrain much of the day. Winds increased in speed out of the northwest through the afternoon. Observed snow transport onto east through south-facing slopes at near treeline elevation band. Snowfall was often light with a short period in the early afternoon that was around S1/S2. Accumulations from 930 to 4pm around 2 inches.

Snowpack: Storm totals reached ~9inches at 11,000 feet at 330pm. Snow was fairly dense. East through south-facing terrain up to 11500′ had soft crust underneath the most recent snow. Found soft drifts up to 14 inches on leeward southeast slopes. A brief period of sun midday put a soft crust on east and south slopes. Experienced some minor cracking on drifted features, but no signs of instability on northerly terrain. Sloughing was minimal on north slopes. Wind texture and stiffening were present on most open slopes.

Location: Paradise Divide Area
Date of Observation: 03/30/2020
Name: Abby
Subject: Schuykill Ridge Birthday Bowl Nose
Aspect: North East, East
Elevation: 11000

Avalanches: Wet slab on skiers left birthday bowl. New snow (2-4inches) slid easily over crust on sun effected aspects.

Weather: Light snowfall, partly sunny, no wind.

Gothic 7am Weather Update

CB Avalanche Center 2019-20 Observations

Location: Paradise Divide Area
Date of Observation: 03/30/2020
Subject: Gothic 7am Weather Update

Weather: Some snow after dark for a couple hours and then a bit more starting around 4 a.m. so new snow totals are 3″ with a light 0.17″ of water. snow pack is at 48½”. After a cold start to yesterday (2ºF) it is milder this morning with a low of 19F and currently 22F. No wind which is nice. Currently obscured with light snow.

Cornice – Red Lady skin track

CB Avalanche Center 2019-20 Observations

Location: Crested Butte Area
Date of Observation: 03/29/2020
Name: Dave Bum
Subject: Cornice – Red Lady skin track
Aspect: North East
Elevation: 11,600

Avalanches: Cornice Fall near the cliff band section of the Red Lady skin track.
Surprisingly close to the track that everyone uses. 10+ people where ahead of us. It failed right after we past it.

Weather: Time 11:45 which was right before the weather rolled in and probably the warmest part of the day with the most solar.
Wind: Calm

East face Cement Mountain

Location: Cement Creek Area
Date of Observation: 03/29/2020
Subject: East face Cement Mountain
Aspect: East
Elevation: 12,200

Avalanches: Cornice fall triggered R2D2 slide within the last few days. Looks to have run about 1,000 vertical feet.

Upper Cement/Brush Creek

CB Avalanche Center 2019-20 Observations

Location: Cement Creek Area
Date of Observation: 03/29/2020
Name: Zach Kinler
Aspect: North, North East, East, South East, South
Elevation: 9,000′-12,400′
Avalanches:

Hunter Hill 12,500′ ENE- 2x D2.5 Persistent Slab
Lambertson Pk 11,800′ W- D1.5 Persistent Slab
These avalanches were estimated to have run sometime during the 3/24-3/26 wind event, likely being triggered by cornice falls.

Weather: Increasing clouds with light snow showers developing over higher terrain by afternoon, light to moderate S/SW wind on ridgeline. Temps above ~11K remained below freezing.

Snowpack: 1-2″ HST from Friday/Saturday’s shortwave. Southerly breezes would occasionally move small amounts of recent snow onto leeward aspects above tree line however minimal recent wind slab development observed in this area. Stacks of crusts present in the upper snowpack on sunny slopes. Recent large avalanches and cornice falls were observed on drifted easterly alpine features similar to what has been seen around other parts of the area following the wind event.

Wind slabs

CB Avalanche Center 2019-20 Observations

Location: Kebler Pass Area
Date of Observation: 03/28/2020
Name: Steve banks
Subject: Wind slabs
Aspect: West
Elevation: 11,000

Avalanches: 3x D1 wind slabs somewhat intentionally triggered on suspect terrain features in near treeline type terrain.

Weather: In and out snow showers with some sunny breaks as well. Light WSW winds. Cold temps but warm periods in sheltered areas when the sun popped out.

Snowpack: Up to a foot of new snow over a soft-ish crust. New snow was dense and “slabby” and not amazingly well bonded to old surfaces. Did not look below the new snow old snow interface.
