None ExperiencedTouring up in the Lakes Basin it was not as easy to find evidence of recent avalanching as might have been expected. There were a few signs down by Hole in the Wall, but evidence of some of the usual suspect areas up higher in the Lakes Basin were not visible. See the attached avalanche observations with photos for more info on what we did see.
