Observations

Toured up to Mammoth Rock today. Found variable conditions of surface snow ranging from nice powder to wind board to breakable crust.
Started just below freezing but it dropped to -5°C at 1430 in the shade.
Conducted a CT on a WNW aspect at 9,022ft. HS was 320. Results were CT17 SP, down 22cm. Results were at a F hardness interface of small near surface facets sitting on a 4F harness layer.
Light winds throughout the day from the SW and bluebird skies made for a nice day out in the field.
Seemed like there were lots of folks out there having fun.
Poop chute looked particularly wind boardy from our recent N winds
No avalanches or instabilities observed.
