Widespread Natural Loose Dry Cycle that occurred mid afternoon as a result of Moderate PI Rates and very brief periods of solar. Picture depicts where our uptrack was buried. This occurred 2 hours after we had used this skin track. Other notable areas of Natural activity were observed on the East Face of Patsy Marley, several steep lines in the Wolverine Cirque, South Facing Highway to Heaven, and multiple steep lines in the Back Bowls. There appeared to be a density break 3 to 7 inches down, and it was easy to trigger this weak layer on slopes steeper than 35 degrees.
