Waterman trailhead 2,082m/ 6,830' sold snow on ground Boot pen 20cm/ 8" great skin from truck. -1.7°c/ 29°F. snow in great conditions. clouds in the distance around peaks towards Dawson and Islip but sunny and clear at trail. 2,182m/ 7,160' East slope 25cm/ 10" storm snow to ground Dug a pit just off the top of the summit to get an idea of the pack 2,426m/ 7,960' the snow showed good bonding and the bond of new snow to the late Dec. Base that had gone through a melt freeze and rain creating an ice crust at the interface. See the attached pit profile for a more detailed look. There were two obvious rain events at the start of this storm with snowfall in between at 11cm and 17cm in the profile. this all began on Jan 7th and on Jan 10th we had rain turn to snow followed by another shot if rain before the steady snow. These layers may become a concern with some significant loading but well well bonded at this time in this location. Coverage was still thin with low tide consequences. Made cautious light turns and the snow was fantastic. Publish this observation Yes I would like this observation Published |
