MOAB Mother Of All Basal weak layers
At the 12th annual USAW (Utah Snow and Avalanche Workshop) I gave a presentation on the epic avalanche conditions we experienced in the La Sal Mountains last winter. It all started with early-season October snow, followed by an extended period of high pressure, just like many mountainous areas in the Intermountain West are experiencing right now. We are currently high and dry in the La Sals, but for those of you who live in areas with snow, pay close attention to where it is and how weak it becomes.

Last Sunday, my partner and I headed toward the Pine Hollow area in upper American Fork Canyon to access the north side of Timpanogos. It may be one of my favorite places in the entire Wasatch Range. We got a late start and worked through the Timponeeke campground, west into the Corner Pocket and then followed an efficiently-set skin track up through one of the weaknesses to gain the Woolley Hole. To our surprise (we were headed toward the Pika Cirque), and then - I can't think of a better word - appreciation - the skinner continued up the east facing ski runs of the Woolley Hole and …Read more
