The Bull Draw Fire, burning in a remote area 12 miles northwest of Nucla, grew to 26,370 acres as of Wednesday morning, the Type 2 Blue Team said.

Containment remained at 19 percent, compared with an estimated 12 percent on Sunday. The estimated date for full containment is Sept. 15.

The fire is considered the top priority in the Rocky Mountain region, meaning that the team would be the first to receive new resources. About 388 personnel were working on the fire as of Wednesday morning.

Tuesday’s light rain in parts of the fire’s footprint did little to slow the fire, and the storm’s winds pushed the fire northwest and south.

The fire grew 3,410 acres Tuesday, spreading northwest in the Campbell Point/Coyote Basin and south into the 2004 Campbell Fire burn scar.

Engines and crews worked around homes in the Campbell area and built control lines that connected to the Campbell Fire scar.

On Wednesday, the fire grew 1,180 acres as it pushed north into Deep Canyon and threatened to spread on the canyon walls.

Engines continued mopping up scattered pockets of heat around homes at Campbell Point.

On the eastern flank of the fire, crews were felling hazard trees, thinning the forest edge and preparing for burnout operations later this week.

The Minnesota Incident Command System Type 2 Blue Team said the southern edge of the fire has two operations. One uses hot-shot and hand crews to build control lines on the fire’s edge up to where it has stalled inside the 2004 Campbell Fire burn scar. The other uses heavy equipment, including bulldozers, to build a second line of defense to keep the fire from turning back toward homes and ranches in the Nucla area.

The western side of the fire was moving slowly toward natural fire barriers and was unstaffed.

On the northeastern edge, crews were felling hazard trees and preparing the Divide Road for burnout operations later in the week.

Incident commander Brian Pisarek has referred to the Bull Draw fire as a “long duration fire” that will continue to grow.

The fire was discovered on July 29 and was apparently caused by lightning.
