Slide on Chimney Rock. The one on Chimney Rock (triggered Sunday, Jan 8th) was not big, but more indicative of weak layers at the ground. Chimney was 2 slides side-by-side, mid-slope, that likely went at the same time. These likely broke on facets near the ground. The snowpack was thin there. GNFAC photo.
