Wasilla photographer and blogger Bill Hess is back in the Arctic this week, and he has posted a series of photos of an encounter between a daring dog and a polar bear dining in the Kaktovik whale carcass dump. Go to Hess' website to see the whole confrontation, from first bark to hasty retreat. Hess says the dog seems to love being chased by bears.
Photos by Hess were featured last year in the Lens blog of The New York Times.
