Noted what we believe to be a natural slide near twin lakes pass today. We passed by this slide around 1pm. Winds were light for most of the day loading east and northeast aspects today and it was easy to identify deep wind drifted slopes on the ridge line towards Patsy Marley. As a natural release this slide caught me by surprise and I wonder if someone triggered it poking over the ridge to have a look... if that's the case hopefully they let us all know. Otherwise this tells me that the new/old interface is touchy and when this storm forms a more cohesive slab we will have some avalanches in our future. The crown wrapped around the corner to a more eastern aspect and appeared to be about 15-20cm deep.

Today in other locations of similar aspect and elevation we noticed cracking and touchy conditions in soft wind drifts.
