Be aware of your surrounding. Here is a video of what can happen when a glacier calves.
Alaska glacier calving clickyWhat I went looking for was a news article from 5 - 10 years ago when a tourist was killed by a glacier calving. North of Cordova on the old road there is a lake with a glacier on the far side. A large chuck of ice calved off and sent a sunami type wave accross the lake to where the tourists were taking pictures. When the wave hit the shallow ground on the other side of the lake, it came like a sunami and got them. At least one of them died.
So if you're kyaking near a glacier, watch for waves from the calving ice so that one doesn't roll you over. The water is about 37 degrees and there's a usually a wind.
