There were other parties ski touring Pilot Peak, but we were pleased to run into one of my peers, Scott a BSU Geophysics graduate student. Same story as last week, all parties used Pilot Peak road to reach the 7000 feet level, when there is sufficient snow to leave the road and skin up to Pilot Peak North and East aspect ski runs between 7000 and 8100 feet.

Snow surface temps were in the -12 deg-C. The recrystallization of precipitation particles is the result of steep gradients (warm snowpack underneath the new snow and cold temperatures). Snow surface gradients were measured in the 2.5 Deg C per 10 cm, higher than the critical 1 deg c per 10 cm.
Check some of the pics of fragmented/stellar, SH and NSF crystals taken today at Mores Creek Summit (MCS). You had to go deep in the snowpack to fid round grains!

Early in the morning, we observed at lower elevations graupel.
But some of the graupel showed marvelous surface hoar formation - SUPER COOL! Check the next pictures.
As we climbed up Pilot Peak road, close to a dozen of snowmobilers went by us at various times. With the exception of two snowmobilers w/o backpacks, all snowmobilers carried backpacks with shovel and probe, and half of them had SnowPulse air ballons. I was happy to see so many of them with rescue gear!
