Route & General Observations

Ventured to Summit for a tour and look at the new snowfall/effects from the recent system that moved in over new year’s. We picked our way up the southeast mining road to get some elevation without any larger slopes above us. Decided to dig a pit due to the surprisingly light snowfall and the good weather.

Weather & Snow Characteristics
Please provide details to help us determine the weather and snowpack during the time this observation took place.

Warm but dry, with no active snowfall at the time of our tour. Very light breeze where we ripped skins at 2300 feet

Snow surface

About 40 cm of new snow


See snow pilot. We witnessed a very reactive interface between the new snow and old snow. The basal facets in this south-facing pit appeared to be rounding. No significant concerning results at the ground in this pit with CT/ECT/shovel shear. In east-facing pits dug on 1/2/23, the facets were more granular and reactive.
