Northern Gallatin

Went for a tour up Blackmore, dug a pit high on the East face. Included approx location. Snow depth was 100cm, I got ECT-P 21 in my test. Broke 35cm down, fist to 4F cohesive wind slab breaking on a 5cm thick layer of 1-2mm facets. Q1, and at least two additional obvious layers from 60 cm to the ground. Lotta facets from 40cm to the ground. 
 

That kind of slab is my ultimate scary moderate. I backed off the slope and skied mellow terrain out. Calm skies, cold. Snow had been impacted by wind all the way down, funky and variable. Beautiful day to be out though! 

I took a tour up the main fork of hyalite and approached a west facing wall near hyalite lake. at around 9200 feet I dug a pit to check the snow pack
I could tell the snow pack structure was not great because while skinning up I would either sink deep into the snow pack or stay on top the wind crust
Here is what I found
Slope angle 37deg
105 snow depth
ECTP 20
Failed 25cm off ground on large grain facets
Snow structure was not good and I did not ride that slope and went back down my skin track

The wind over the past week really hammered the snow above hyalite lake

I did find good riding below the lake

We skied divide peak this morning. The snow surface is wind affected in some areas but SE facing slopes near the E ridge provided good skiiing. We dug a snow pit at the base of Divide Peak (approx. 9300 feet, location on map below) in an open meadow south of the summit. Snow depth was 110 cm. Old faceted snow formed the lower 45 cm of the snowpack with a distinctive hard crust 35 cm from the ground. The top of the snowpack was well bonded and right side up. Stability test result: ECTN.
