Tour up Grizzly under Emma Ridges to Twin Lakes Pass. Then up to Patsy shoulder. My main objective was to look for wind slab over the weak snow and test for propagation. I did not see any cracking or collapsing and did not find any wind slab. Two ECTs at 9800' and 10300' respectively did not propagate. The overlying slab is still too soft in the areas I visited. Lots of tracks on every aspect with large groups sessioning the upper Patsy Face with no results.
