Blowing snow over crest at Hidden peak

Toured up hidden peak from 89 today. We saw blowing snow moving from E to W across the peak/crest. I was suprised to see snow available for transport. When we got to the top we were also able to clearly see snow blowing across a shoulder of Tallac and deeper into desolation wilderness. 

Above 8400 we saw what i think was small surface (2-3mm) hoar in open areas on NE aspects. 

Other than that, very variable snow. Felt like nothing lasted more than 20'. We ascended roughly 9:30-12:30 and descented 1-1:30. Every kind of crust and pockets of softer snow. Wind scoured at the top. By the time we descended everythin was pretty much refrozen, including our brief moment of sun exposed, SE facing terrain. 

Kind of hard to tell from the photos, but photo 1 is looking up blowing snow at hidden peak on the ascent afer the bench at 8300, and photo 2 is from the top looking into desolation with blowing snow indicated.
