I believe that bear was killed on one of the islands off Alaska.
http://en.wikipedia.org/wiki/Kodiak_bear
The largest bear ever killed in North America was from Kodiak Island with a total skull size of 30.75 in (78.1 cm), and 8 of the top 10 brown bears listed in the Boone and Crockett record book are from Kodiak. The average skull size of Kodiak bears that were killed by hunters in the first 5 years of the 21st century was 25.1 in (63.8 cm) for boars and 21.8 in (55.4 cm) for sows.
Size relative to other bear types
The Kodiak bear and the polar bear are the largest members of the bear family. Physically, Kodiak bears are similar to the Kamchatka Brown Bears of the Russian Far East, though tending to be lighter in colour and bigger.
