Good Stability on Boott Spur Ridge 2018-12-13

Location of Observation: Boott Spur Ridge
We climbed Gully #3 from Hermit Lake to the ridge. The lower third was post-holing in breakable crust with very sugary snow beneath while the upper climb was supportable melt-freeze crust (from December 3). Cross-loading over the past week has left an isolated pocket of wind slab in the lee of the trees that separate #3 from Cathedral. We climbed down into the Fingers in Gulf of Slides, finding exposed melt-freeze crust with no new snow. Hillman’s Highway for the ski down was mostly hard wind slab. We stopped near the Y and found from 15-40 cm of snow on top of the melt-freeze crust. Pencil hard on the surface with a mix of 4F and 1F below. Stability tests were CT21 Q3 @15cm, CT 24 Q3 @15cm, and ECTX.
