FAIRBANKS — Five more firefighting crews from Alaska have left for the Lower 48 to help battle a large wildfire burning in and around Yosemite National Park in California.

The five 20-person crews flew out of Fort Wainwright just after noon Wednesday. The crews are from the villages of Allakaket, Nondalton, Huslia, Hughes and Stebbins.

All five crews were assigned to the Rim Fire, which had burned almost 300 square miles as of Wednesday. Approximately 4,100 firefighters are working on the fire.

 It was the second plane-load of firefighters to head to the Lower 48 from Alaska this week. Five crews flew south on Tuesday to help with fires in Montana, Idaho and California. There are approximately 300 firefighters and firefighting personnel from Alaska working in the Lower 48.
