I reported these results as they were not the norm this morning for our teams. The explosive triggered slide mentioned above is a N-NW aspect off Millicent Peak above Twin Lake. This area recieives alot of wind and did not hold snow until mid Jan. The shot landed in thin rocky area and propagated deeper from there. This was the only event into old snow for our teams today. Today was the first time in a while that control results were negative and/or isolated to new snow.

However by noon we had receive report of a unintentional user triggered slide off Pioneer Ridge above Dog Lake. Reported as 12-36 " deep 400 wide. We have not seen natural activity in this area since before this weeks storm. This area has seen substaintial traffic this week. As I write this I am receiving report of yet another human triggered slide West of the first off Pioneer Ridge 3' deep 20' wide pushing user into trees. Perhaps the weight of a human is tipping the scales.

Just a note- Aspect and elevation of these 3 slopes is almost identical

Forecaster note (Bruce Tremper): I was returning from looking at the Tuscaroroa slide when I heard about the Pioneer slide and I went to the toe of the debris to look at it. While I was digging in the snow, a lone skier descended from above and said that he triggered an avalanche to the west of the avalanche I was looking at. He said it was 3' deep and 20' wide and it pushed him into a tree but he was OK. Very lucky!
