BANNING, Calif. -

A fire in the San Gorgonio Wilderness east of Banning has scorched up to 1,500 acres and was 15 percent contained today, according to the U.S. Forest Service.

The blaze started shortly before noon Sunday in the northern part of the Morongo Indian Reservation and was burning today in "steep, rugged terrain" in a remote area, according to the Forest Service.

"There is continued potential for large fire growth into the San Gorgonio Wilderness," according to a Forest Service statement.

Several helicopters and water tankers, and more than 30 crews from federal, state, county and Native American agencies were sent to fight the fire.
