Quick report
- Cracking
- isolated
Overall, there was considerable variability in the snowpack of Main Gully. The lower, choked-out part of the gully (up to ~4300' where our pit was dug) was very weird. The recent melt-freeze crust was sitting on top of graupel that came halfway up my boot, probably close to 30cm worth. Higher up, the crust transitioned into windslab. It was fairly reactive where we dug our pit, but as we climbed higher, it became more stubborn and much thicker. Other than the isolated instability noted above, things felt generally pretty stable, and good turns were had higher up. Isolated slabs in the bottom of Main Gully. Cracking in the crust layer on top of 40ish cm of graupel.

Snowpack
Dug a pit in Main Gully at around 4300'. The pit was dug on the climber's right side of the gully, right as it starts to fan out. Total snow depth was 155cm. Pit depth was 65cm. The top 5cm of snow was refrozen crust from the melt-freeze events over the past few days. Beneath this was 20cm of 1F snow on top of 15cm of 4F snow, on top of another 1F layer to the bottom of the pit. An ECT was performed, resulting in ECTP11 25 cm down on the 1F/4F interface. Pulling the block resulted in a Q1 shear.
