Route & General Observations

Went up into the Pinnacle basin for a high north steep face but did not continue due to recent wind drifts up to 12″ thick forming a slab sitting on Near Surface Facets, seemed like our objective would have had the same set up or even a bigger and thicker slab. Moved over to Eldorado bench for one other run in flat light.

New snow was not bonded well where it was sitting on near surface facets. Easy hand shears here with one hand pit failing on isolation with sudden planner character.
