(AP) - Firefighters in California and Arizona have increased containment of a wildfire in a desert marsh area along the Colorado River.
Arizona State Forestry spokesman Mike Reichling says the blaze is 40 percent surrounded Thursday morning after burnout operations overnight.
The fire's size officially remains at just over 1,400 acres but the burnouts are expected to add a couple hundred acres to the total.
Hand crews and two helicopters are continuing to work the blaze.
The fire began Wednesday on the Arizona side and jumped the river about 11 miles southeast of Needles, California, near the Pirate Cove Resort.
The only property damage has been a small fire on a thatch roof of a bar.
