Date of Observation: 02/16/2021
Name: Ian Havlick

Zone: Southeast Mountains
Location: Coneys with visibilitiy to surrounding backcountry
Aspect: North East, East, South West, West
Elevation: 9000-11,200

Avalanches: Fresh D2+ avalanche west facing Gothic. Impressive propagation and crown depth zig zagging into treed terrain and skipping over terrain features. Debris ran long into runout, though not to historic trim lines. Looked to have failed as a storm slab or windslab above treeline and propagated horizontally at near treeline elevation. Observed a number of other D2 sized pockets in obscure undulating terrain near rock Creek and Elkton, though visbility was poor enough to prevent good photos. These smaller slides (<5) failed on south to southeast facing terrain BTL.

Also, observed D2+ avalanches on NW facing Double Top in Brush Creek as well as D2 avalanche on SW facing slopes above Deer Creek.

Weather: snow showers, bried S2. Accumulations <3″ in Washington Gulch, though multi day storm totals in the 24″ range.

Snowpack: increasing depth to ~120-140cm, still weak facets near ground. New snow pasted, generally right side up density strucutre.

Name: Cosmo Langsfeld

Zone: Southeast Mountains
Location: Cement Mtn
Aspect: North, West, North West
Elevation: 9200-10000

Avalanches: Big north bowl on Cement Mtn (horse basin) looks to have slid before or during the last storm, maybe wall to wall. Could see outline of crowns beneath new snow (no good picture). Wasn’t high enough to see far lookers right of bowl, the east/northeast facing slopes, but everything lookers left of that went.

Weather: Sunny and clear overhead, but looked cloudy everywhere else around. Cold in the wind. Warm in the sun.

Snowpack: Trapdoors in the valley bottom. Largely supportive above 9400′, but you can usually punch through if you jump on it. True northern facing and shady stuff is still mostly facets. Too many collapses to count. Some of them rumbling away from me for a few seconds after the initial collapse. All supportive snow was suspect. Some snow depths: 60cm in northwest facing aspens @ 9400′, 75-90cm on W-NW terrain 9600-10000′. One southwest facing slope @ 9600′ was 25-35cm with a 3-4″ crust sandwiched between new snow from Friday-Saturday above and facets below and a new crust forming on top (no collapses on this southerly terrain, but I also didn’t spend much time on it).

Name: Ben Ammon

Zone: Southeast Mountains
Location: Coneys
Aspect: North, North East, East
Elevation: BTL/NTL

Avalanches: Slab avalanche in West Side of Snodgrass, ran sometime between 0900-1200 on 2/14, same slide pictured in Briebart’s ob.
Shallow storm slab on West Side of Gothic (pictured)
Persistent slab x2 in SE bowl of Elkton Knob (pictured)
Observed a very large crown just below ridgetop on SE/E aspect of Quigley Basin on Baldy, only photo I could get looked like garbage.
Weather: OVC with a couple brief periods of sun before 1200, then clearing in the afternoon.
Winds were calm but starting to be light and blowing up Wash Gulch. Afternoon/early evening winds appear to increase dramatically up high.
Snowpack: No cracking/collapsing observed in lesser travelled terrain at Coney’s.
NE @10,500′ HS 185-190cm
ECTP23 down 60cm, ECTP30 down 120cm, PST110/130 END down 120cm

Name: Andrew Select Breibart

Zone: Southeast Mountains
Location: Washington Gulch-Coneys
Aspect:
Elevation: BTL

Avalanches: On the skin out today, I observed a D1/D0.5 avalanche on the north ridge of Snodgrass Mountain in Washington Gulch: BTL on W/ SW aspect in a drainage. Poor visibility on 2/13/21 prevented me from observing this avalanche. It likely failed 2/12-2/13 but I am uncertain.
Weather: calm. mostly obstructed skies. patchy S-1/S1 snowfall with no snow loading.
Snowpack: 2 to 4 inches of new snow in skin track. HS at one ridge top location was 155 cm. Same as yesterday, no cracking, collapsing, or whumping on/off skin track. Same plan as yesterday.

Aspect:
Elevation: 9250′

Avalanches:
Weather: Snow fall quit by mid morning Sunday. ~10″ of new snow since Friday afternoon/evening. That might include some of the snow that fell later in the day on Friday, but most is from Saturday/Saturday night.
Snowpack: As of Friday, the new snow from middle of last week had been blown into 1F-4F windslabs in the valley bottoms. The ones I found were 4-8″ thick. Found a very thin (<1cm) sun crust on some aspects and in the flats just below newer snow (maybe from thursday?). HS in flats is about 2-3 feet, though deeper in wind pockets, shallower where wind scoured. Snow depth of hillsides varies greatly depending on aspect.

Name: Marcel Medved

Zone: Southeast Mountains
Location: Road above Death Pass
Aspect: East, South
Elevation: 9,500

Avalanches: We decided to avoid Death Pass, due to recent snow fall and multiple avalanche sightings returning from Friend’s Hut. Cornice Drop and Slab Avalanches around entire curve, as well as below the road. We caused cracking and set off a smaller slab avalanche below the road from 50-100′ away.
Weather: mid 20F, relatively calm.

Zone: Southeast Mountains
Location: East Brush Creek Trail to Friend’s Hut just above the 3rd Creek Crossing
Aspect: East
Elevation: 11,400-10,400

Avalanches: Entire hillside (.4miles wide) slide from ridge to and across the creek, crossing the winter trail in one area (100-200yards wide). We came across this at 11am and it only had 1-2″ of fresh on top of it, so it ran Saturday 2/13 around 9am.
Weather: At Friend’s Hut it was around 20F with 12″ of fresh powder over night, bringing the total since 2/9 to around 24″.

Date of Observation: 02/13/2021

Zone: Southeast Mountains
Location: Snodgrass East/Northeast line
Aspect: North East, East
Elevation: 9000-11100

Avalanches: No observed, saw evidence of slides from previous day; could only find one trigger point that produced a small collapse.
Weather: Low vis, S1 in the morning, moving to S2 by afternoon. No wind. Temperature in the high 20s.
Snowpack: About 2-3 feet of snow from the last two weeks at F-F+ hardness, which sat on top of a 2-3 inch P- 1F hard layer, which sat on about at least a foot of large grained facets.
