Analysis

After making a low pass over the runway and noting that it was plowed with berms on both sides and that there were bare patches on the runway the pilot elected to land. Shortly after touchdown the left ski encountered a bare spot on the frozen snow and ice covered runway. The aircraft veered to the left and impacted a frozen snowberm.
