Short tour from the resort.

Our group did a short tour from Lost Boys to Mammoth shoulder today. It was overcast with moderate wind from the SW and some light snowfall. We found the persistent weak layer in the upper snowpack (see photo) and had some small pillows crack and fail on this layer. There was an old slab avalanche (that we observed from afar) on the back of Elephant head in steep, alpine terrain, S aspect. It looked like a size 1.5 or 2.0 and likely occurred a few days ago. There was also some sun crust on a SW aspect that we skied.
