It was in the 40's most of the day, wouldn't be surprised if it got up to the 50's in the upper basin. The dusting of snow on Grays was from the night before, the drifts just haven't melted from last year.
Had to work the clothing layers all day. Had a hoodie, t-shirt, and underarmor shirt to start, then about halfway up got into the sun (sunrise) and was roasting so I took my hoodie off. As I got into the snow, I put the hoodie back on. Needed a windbreaker jacket and gloves once I got to the summit of Grays. Jacket came off half way to Torreys. Hoodie came off at the summit of Torreys. Hoodie went back on for the decent.
