Firefighters are gaining the upper hand on the East Fire in the Kaibab National Forest.
The lightning-caused fire, which is one of numerous lighting-sparked fires this week around the state, is now 35 percent contained. Fire officials expect to have the fire fully containment by Thursday.
Crews made progress Friday on multiple blazes in remote sections of Arizona, officials.
The East Fire, which was discovered late on Aug. 8, is the largest, burning on about 1,958 acres in a remote area on the far west side of the North Kaibab District along the Arizona-Utah border.
It has been fueled mainly by dry grass and pinyon-juniper trees, but officials said it's progressing toward terrain with sparser vegetation.
"Today, firefighters will conduct mop up operations, in which they seek out and extinguish hot spots within the fire's perimeter," a news release said. "All containment lines are holding, and firefighters expect to continue making progress in containing the fire today."
Officials dispatched six engines and three crews among other resources to battle the blaze.
Also in northern Arizona, the Le Fevre Fire, has scorched 1,058 acres eight miles southeast of Fredonia, according to officials. It's about 50 percent contained at last, according to most recent updates from fire officials.
Crews have also made significant progress on the fires that burned remote areas of the Tonto National Forest.
According to Tonto spokesman David Albo:
-The Woodbury Fire, which grew 280 acres in a remote section of the Superstition Wilderness, is being monitored but has produced little smoke and notable activity.
-The 70-acre Mistake Fire in the Tonto Basin Ranger District is the most active of the fires in Tonto but crews have had success with containment.
- The McFadden Fire in the Pleasant Valley Ranger District was close to containment after burning 9 acres.
- The Houston Fire in the southwest section of the Hellsgate Wilderness has burned three acres and has shown little activity.
- The Mesa Fire, which burned two acres in the Salt River Canyon Wilderness, is no longer producing smoke after the area received rain. Crews continue to monitor the area.
- And at less than a half acre, the Granite Fire is the smallest fire in the Tonto is burning in the Mesa Ranger District and has seen no significant activity.
