This picture looks nnw at the tracks from the truck in incident #13 as they approached the pressure ridge. Missisquoi Bay, Alberg VT..
Summary: We had a relatively short, low snow season. This resulted in a lot of skating and other activities. The 18 incidents represent most but not all incidents. There were many more partial breakthroughs involving vehicles with quick recoveries (mostly 4 wheelers). Fold down ridges were involved in almost half the incidents. There were two serious injuries (concussion and broken hip). We do not have a good enough estimate of the number of participants to make reasonable estimates of incident rates.
