Dug a pit on the east facing slope around 7800'. The snow was 60 cm deep. We got ECTN11 and CT12 RP 15cm down on the old/new snow interface, ECTN16 25cm and CT19 25cm down on a crust.

Also dug a hand pit on a south slope at 6800' to test the new snow and it didn't break easily or cleanly.

We didn't observe any whumphing or cracking.

ECT-P-5 on Blackmore

Date
Activity
Skiing

Headed up Blackmore Sunday 12/15, late morning, was pleasantly surprised by the amount of new snow. Not sure how much was brand new, but up below the summit seemed like about a foot of fresh. Skinned to the ridge above the east face, plenty of wind at the ridge, dug a out on the east slope just below the ridge a bit north of where most people ski down in snow that was not wind affected. Isolated column test clearly showed a weak bond between new snow and old, decisive ECT-P 5 on the extended column test. Skied the trees out.

On our first column test was CTX and slid on the saw cut, in the video we didn’t get the same result but still very reactive.
 

During our extended column test we were at 9500ft on a North slope.

Notes

I observed a large whoomph about 150ft from the ridge (top of glades) going up Blackmore today while breaking trail. was definitely wind loaded area… I could feel the energy in the snowpack today once I got up higher, super sensitive it seems. ECTN 14 in my pit I dug lower down the meadow with no wind slab prevalent.
