I was finding some of the wind slabs to be reactive to the weight of a person in the more wind exposed terrain. Second photo: winds have been stripping snow from the southerly aspects and depositing it onto the northerly facing slopes.
Generally about 2-3' of snow in the Whitney Basin with fairly good coverage, but some stumps and rocks are still thinly covered. Second photo: decent riding can be found in the meadows and grassy areas.
I observed this natural avalanche from a distance on a very steep north facing slope with likely weak snow that was overloaded from recent strong south/southwest winds. I do not know how recent this slide is?
