Comments
From an email sent to the UAC:
Toby, we saw your truck at Tony Grove Friday. We were hoping to catch you on our way out but you had already left. Friday afternoon we triggered a fairly large and fairly fast running avalanche while snowmobiling on the hill above the south end of Tony Grove Lake. We had been riding all day and the new snow seemed to be sticking well to the previous layers, so we were surprised. I was sidehilling and it gave way below my track. No one was caught in it or hurt. Sorry, we didn't get a photo. Thought you'd like to know.
