Snodgrass-GFP freshner

CB Avalanche Center2018-19 Observations

Location: Crested Butte Area
Date of Observation: 01/11/2019
Name: ADB

Subject: Snodgrass-GFP freshner
Aspect:
Elevation: BTL

Avalanches:

Weather: Obscured skies morphed into broken skies. Temperatures warmed up to around freezing. Light winds and one burst of moderate wind that blew snow up on the road for a minute or two.

Snowpack: Less than 2 inches of new snow, closer to one inch.

No cracking or collapsing observed on filled in skin tracks or newly formed skin tracks.

Disclaimer: These are very hasty tests with non standardized column dimensions.
Performed dirty hand tests:
2 on SE Slope were within CT10-15 with Q3 shears. Both were very sluggish on buried surface hoar (?) about 8 to 12 inches below snow surface. (skin track in trees below the RMBL weather station).
1 on W/SW aspect had CTN. Did find a 1F crust below 12 inches of F hardness snow. (road cut above the RMBL weather station.

Avalanches:

No signs of instability, previous sluff in the bowl as reported.

Weather: Clear skies with some overcast clouds developing, temp around 22 with little to no wind.

Snowpack: Snowpack was supportive with variable conditions, light to firm crust mixed with good snow all the way up and down, wind scoured at the fence posts.
The descent was difficult at times due to the breakable crust.

Avalanches:

Weather: Thin cloud cover and pretty warm

Snowpack: Dug a pit just north of the snodgrass saddle on a northeast face ECTN13 failing under the storm snow but not propagating. Less than 5 minutes later got a massive collapse with shooting cracks on a slope right around 30 degrees.

Mountain Weather for 11,000ft

CB Avalanche CenterWeather

Date: 01/11/2019

Those cold valley inversions got pushed out last night with temps around 20 at both valley elevations and 11,000ft. We got a dusting of snow overnight with CBMR getting 50% more snow then the typically favored Irwin. Unfortunately, we are only talking 2” vs 1”. This is the setting for this storm, as more snow will accumulate further east, primarily in the Sawatch and out to the Front Range. We’ll continue to see overcast sky in our forecast area and could pick up another inch or couple today. Winds look to tick up slightly this afternoon as well. Looking at the weekend, we’ll continue to see clouds hanging out in the area and a couple more inches of snow toward the end of the weekend. Looking at the start of next week, moisture appears to undercut the high-pressure ridge we were talking about yesterday. More on that later, but for now it doesn’t look like clear weather to start the weak.

No hate from the Slate

Location: Paradise Divide Area
Date of Observation: 01/10/2019
Name: Roscoe

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.

Check in on Coney’s skier triggered avalanche

CB Avalanche Center2018-19 Observations

Location: Crested Butte Area
Date of Observation: 01/10/2019
Name: Evan Ross And Eric Murrow

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.

Mountain Weather for 11,000ft

CB Avalanche CenterWeather

Date: 01/10/2019

Another clear and inverted morning as valley temps are near 10F in Crested Butte and 25F at 11,000ft. Temperatures will again rebound nicely today. Clouds will begin increasing today ahead of a small storm for Thursday Night into Friday. Looks like we are kinda getting left out on this one. Hopefully we’ll pull off a couple inches in the Kebler and Paradise Divide areas, otherwise, the better snow will develop further east then Crested Butte. We’ll see another ridge developing later this weekend and bringing dry weather for that period and to start the week.
