Avalanches:

Avalanches observed post-storm across Ohio Pass road, cleared and groomed by SnoTrackers 1/10. Impressive debris. Photos show avalanche, debris, and topo map with hillshading to show slope steepness. 30º= yellows 40º=reds 45º+ = purples

Avalanches:

Un-Opened terrain representative of backcountry snowpack.

“Flatiron R2D2 ran full track and multiple slides R2’s in highlife stepping down below T-day interface very weak snowpack on N aspects not reactive to bombs but ski cuts loose dry.”

Aspect: North East, East, South East, South
Elevation: 9-11,000

Avalanches:

I was on the road then skiing E, SE slopes, so the only collapsing, cracking was when we approached that steep NE slope.

ENE slope, below treeline, a little steeper than 30°
Crown about 45 cm tall, about 20 meters across, ran the length of the slope, about 40 meters.
Remote triggered (by me, riding) from a ENE slope about 10 meters away.
Ran on NSFacets. Shallow snowpack, about 1 meter deep.

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.
