Quick report

Our goals today were to monitor faceting near treeline both at the surface and around the 1/1 crust. 

We walked on dry ground up the Sherwins bootpack. We dropped in to Mammoth Rock bowl and dug 100 feet below the ridgeline. Surface conditions were the familiar mix of wind board,  melt-freeze crusts, near-surface facets, sastrugi, and dry ground. 

Coverage is still sufficient throughout the lakes basin, with the exception of the most solar and windward slopes.

Regarding our goals, the faceting continues. With a glimmer of hope for snow in the five-day window, its a good time to start paying attention to surface conditions in your favorite zones and to consider what any new snow may interface with.
