CHEYENNE, Wyo. (AP) - Gov. Dave Freudenthal toured a wildfire burning in rugged terrain about 20 miles west of Dubois on Friday to see how well crews are prepared to protect nearby buildings.

Freudenthal toured the 19,000-acre Purdy Fire by helicopter.

"There are about 560 people assigned to the fire, along with a significant number of aircraft," Freudenthal said after the helicopter tour with members of the incident command team. "It is rough country, and the firefighters are working pretty much around the clock."

The fire is burning on federal land. About 12,000 acres lies on the Bridger-Teton National Forest, while the remainder is on the Shoshone National Forest. Cooler temperatures and moisture were helping firefighters on Friday.

Elsewhere in Wyoming, the Outlaw 2 Fire had burned over 12,000 acres by Friday evening in an area where famed outlaws Butch Cassidy and the Sundance Kid used to hide out. It has destroyed a restored historic cabin linked to the Johnson County War of the 1890s.

Spokeswoman Lesley Collins said the fire has also burned a shed. She said there are 158 firefighters and three helicopters assigned to the fire.

The fire is burning in timber and grass in the rugged area of the Hole-in-the-Wall, about 20 miles southwest of Kaycee.

The fire was started by lightning on Tuesday, said Diane Martin, with the Casper Interagency Fire Dispatch.

In the 1890s, Cassidy and his band of outlaws made use of the Hole-in-the-Wall area as a hideout after robbing banks and trains. One of the names for the group was the "Hole-in-the-Wall Gang."

The lone structure lost was a cabin on the ranch owned by the family of former U.S. Rep. John Wold, who served in the U.S. House in 1969 and 1970.

Wold said the cabin was first built in 1890 and was the scene of a shootout involving Nate Champion, who was killed a year later in Kaycee by gunmen hired by cattlemen. His death was part of what became known as the Johnson County War between ranchers and cattle barons.

The Wold cabin decayed over the years but was restored recently, Wold said.

Wold said efforts were under way to have the cabin declared a national historic site.

"But of course, that national historic site is in a lot of ashes right now," he said.

Elsewhere in the state, firefighters were battling several fires in remote areas of the Bridger-Teton National Forest and in Platte County, west of Wheatland.
