Notes

Got a view of the bowls behind maid of the mist and above twin falls today. Multiple natural wind slabs, up to size 2, on E and NE aspects, roughly 9500 ft. SS-N-R2D2-I.  My guess is they are roughly 48 hrs old.

Whumpfing and avalanches on Mt. Blackmore

Notes

Toured up toward Mt. Blackmore today with the goal of skiing the mellow SE facing meadow and familiarizing myself with the current unstable snowpack. While stopping for lunch I dug a quick pit out of curiosity and performed a CT at 8757’ on a NW aspect with HS 85cm. Results were CT11 down 17 cm within the new snow on a hardness change and a CT13 down 35 cm on old facets. Moving farther up in the basin we noticed the pictured recent D2 avalanche on the E aspect of Blackmore. As we skinned up the SE meadow, we experienced three audible whumpfs. Otherwise great skiing was found today albeit a bit thin!
