Stupid Moose - why didn't it just go for deeper water where it could easily have outswum the wolf - instead it stayed in shallower water where the wolf had a chance at it.  Even if it had stayed where it was at first, in the very shallow water, it could easily have stomped the wolf - seems like it did the worst thing.  Moose hide is at least a 1/4" thick, so probably little or no damage to the moose.
