Yeah apparently the Chugach area incident recalled by Scottyb involved a bear defending a moose kill.

It was believed to be a brown bear, not a black, and two joggers were killed.

Not too nice. ADFW says it knows of 20 such incidents that occurred in the state during the first 85 years of the previous century. The rate is increasing. There's now nearly 700,000 people there.

I think ADFW (uh.. or maybe it was USGS) also says it knows of 30 people were killed by dogs in Alaska during the 1980s. Their point in saying so is a desire for perspective regarding bears danger. I'm assuming the dangerous dog rate is probably rising too. Both risks are probably increasing only relative to human population... IMHO (in my humble opinion).

The government aims, I do imagine, to put out accurate information, but certainly doesn't want to scare tourists away.
