Southern Gallatin
We toured into the Southern Gallatin Range near Specimen Creek and found a very thin, very weak snowpack that is stable for now because it is missing a key ingredient for avalanches, a slab. For now, we are watching out for areas of isolated instability in areas where there is more cohesive snow sitting on top of weak layers. Photo: GNFAC
