Comments

Heading up MLH there was up to 3 inches of new light snow between about mile marker 17 and 22. Higher than that very little new snow overnight. Heading up to Mt. Watson from mile marker 26 I observer very deep snow which allowed my sled to penetrate 1-2 feet into the snow pack. I was very surprised the snow was not setup better and had to be careful of hidden land mines. I dug at the bottom of the south slope of Watson then skinned/climbed up the south flank. The climb was a mix of 6 inches of powder/blown in snow on-top a melt-freeze layer near the bottom to slide for life ice higher up. I used my whippets on more than one occasion. Once on top the visibility went to less than a 1/4 mile and the wind was ripping from the north. I had to lean into it several times just to stay standing. Since the snow was shot and there was no visibility I survival skied the north ridge. I noticed one small slide all the way near the base of Tyson's skin track which would have caught anyone skinning that location and taken them through the trees at the bottom but likely would not have buried them. Since the snow on either side was pencil hard wind slab and new snow was piling on-top the old slide, I am assuming the slide was triggered by severe wind loading. The sheltered low angle trees below had excellent dry light powder with a mix of very thin melt-freeze crust where ever the snow sun had its way. When skinning back to my sled below the east face of Watson in the non-climax slide safe zone I noticed the north wind had scoured the entire east face of any soft snow. So it seemed the deep snow I experienced on the south slope approaching Watson was the result of the north wind transporting all the snow initially deposited on Watson. In summary, quite a bit of wind scouring in the alpine.
