The father was able to scare the bear off after several attempts then left a note at the campground to notify officials before seeking medical attention with the rest of his family. 

"The bear weighed approximately 350 pounds, which is not standard for this time of year, suggesting the bear had previous and likely consistent access to non-natural food sources," Resource Management Chief Lisa McInnis said in a statement.
