Snowpack Observation 		Blue Lakes
Carson Pass Area 		Great riding conditions in between tree bombs. We found more open and higher elevation cold slopes that weren't ruined by them I took dozens of photos like this today, across several miles of drainages, and only found the occasional feathery surface hoar crystal in the lower density layer just below the surface There were still areas with surface hoar on the surface, but it was already laying down and decomposing in the warm weather Professional Observer
