(AP) — West Texas firefighters are trying to stop a 202,000-acre wildfire from spreading out of a canyon.

The blaze started nearly two weeks ago in Presidio County and then raced into Jeff Davis County, where it destroyed about 40 homes in the Fort Davis area.

The fire grew rapidly, so a team of federal firefighters and officials from several U.S. agencies arrived to assist.

The team's spokeswoman, C.J. Norvell, says although the fire is 75 percent contained, it's still burning in some of that area. She says the blaze in a canyon north of Fort Davis is stubborn, so fire crews on Friday were digging lines to try to stop it.

It's among several massive wildfires scorching more than 1 million acres in Texas in the past two weeks.
