On the weekend of January 10 & 11, one or more snowmobiles accessed the Allison Chinook cross country ski trails multiple times. A fair amount of trail damage resulted, spanning roughly 13KM (40%) of the network. Trail conditions were restored the evening of Monday, January 12th, however, weekend users likely experienced some poor conditions. The ski club is now discussing measures to prevent future occurrences. In addition, several signs stating "no snowmobiles, ATV's or dirt-bikes" have been placed at the entry/exist points as a temporary measure.
