The sensitivity and widespread nature of small "pockets" today was impressive. On any mellow rollover reaching above 35 degrees you could bet with an accuracy that would make Vegas go bankrupt that you would get a small "avalanche". I put it in quotes because what I am referring to were D.5-1 in size and surprisingly small. Probably had 20 collapses and 20 small "avalanches" throughout the day today. A couple pictures attached...although I wish I took more photos.
