Above: Most of the activity on the Pinal Fire Saturday was a firing operation on Divisions A and D as the Payson and Prescott Hotshots were conducting burning operations along the ridge tops. The photo looks south from the western part of Globe, Arizona towards the Pinal Mountains.
The Pinal fire five miles south of south of Globe Arizona slowed on Saturday, adding about 200 acres to bring the total to 6,610 acres. On Sunday the fire was active on the north side six miles south of the community of Miami.
Firefighters have been conducting burning operations along Forest Road (FR) 651 to help keep the fire within the planned perimeter and lessen the impacts of post-fire effects. If conditions allow, the controlled burning will likely last about three to five more days.
All of the photos were taken by Tom Story during the afternoon of May 27, 2017.
Four separate incidents involving hobbyists flying drones are hindering operations on the 4,991-acre Pinal Fire since the fire was detected May 8 in the Tonto National Forest five miles south of Globe, Arizona.
The latest drone sighting occurred May 24, 2017. An air tanker flying over the fire was forced to release its retardant at a higher altitude for safety reasons. The higher drop reduced the retardant’s effectiveness on the fire. Subsequently, aviation operations were suspended until the drone issue was resolved.
On May 20, 2017, a law enforcement officer cited a hobbyist for flying a drone near the Pinal Fire.
Forest Service officials continue to emphasize that flying drones over or in close proximity to wildfires is illegal, endangers aviators as well as crews on the ground, and slows operations which potentially could result in the fire increasing in size.
Deputy Forest Supervisor Tom Torres, Tonto National Forest, explained that flying a drone near a wildfire is, in fact, breaking the law.
“The U.S. Code of Federal Regulations 43 CFR 9212.1(f) – indicates that it is illegal to resist or interfere with the efforts of firefighter(s) to extinguish a fire,” Torres said. “Doing so can result in a significant fine and/or a mandatory court appearance.
Drone operators determined to have endangered manned aircraft or people on the ground and/or interfered with wildfire suppression may be subject to civil penalties, including fines of up to $25,000, and potentially criminal prosecution.
Management of the fire
The Pinal Fire is being managed, not aggressively suppressed. One of the objectives is to create a continuous fuel break between the Pinal Mountains and the town of Globe five miles to the north.
Firefighters are involved in preparation and defense of structures and infrastructure along the indirect control lines from which firing operations could be conducted where necessary to maintain low intensity fire conditions and prevent unwanted impacts to the values at risk.

The new Granite Mountain Hotshots Memorial State Park that opened November 30, 2016 is receiving so much use that often visitors are turned away when the small parking lot is full. Arizona State Parks reports that approximately 10,500 people have visited the site, more than the small parking lot can handle at times.
The park honors the 19 wildland firefighters that were killed on June 30, 2013 when they were overrun by the suddenly very active Yarnell Hill Fire near Yarnell, Arizona, 90 miles northwest of Phoenix.
The park consists of a trailhead on U.S. Highway 89 approximately two miles west of Yarnell and a 3.6-mile trail leading to the fatality site. Along the trail are 19 stone plaques honoring each of the fallen Hotshots and six interpretive signs that tell their story.
The trail is fairly steep with quite a bit of elevation change, up and down, and can take four to six hours round-trip for the casual hiker.
The trailhead is located on an east-west section of the highway where the road contours across a very steep mountain. The highway is divided at that point with the eastbound lane several hundred feet below the westbound lane.
If you are driving east toward Yarnell you will not pass directly by the trailhead — you will see it only if you are heading west. However the state built a new road connecting the two opposing lanes about a quarter of a mile to the east. Signs direct eastbound travelers to turn left to get on the connecting road. Upon reaching the westbound lane, you turn left again and drive down to the parking lot and trailhead.
When I was there on May 19 about half of the 17 parking places were taken. According to an article in the Daily Courier the parking lot often being full has motivated park managers and locals to find a way to keep folks from being turned away. One idea being tossed around is to offer a shuttle.
Below is an excerpt from the article:
The group’s idea is to create a shuttle system that would take visitors from an overflow lot in Yarnell to the state park south of town. The group is looking into grant opportunities to help fund the shuttle, Lechner said.
Along with relieving the traffic frustrations for visitors, Lechner said the shuttle also could help the Yarnell businesses by bringing more the visitors into town.
“The best way to honor the sacrifice made by the Hotshots is to make Yarnell the most wonderful, thriving community as possible,” she said.
Rangers have started using drones to scout fires from above, the Grand Canyon News reported. From the article published Tuesday:
Justin Jager, interagency aviation officer for Grand Canyon National Park, Kaibab and Coconino National Forests and Flagstaff and Verde Valley Area National Monuments, said the drones are utilized in conjunction with traditional methods. Operators use the devices to scout fire lines, or communicate information to other personnel in the area.
The unmanned systems aren’t replacing fixed-wing scouting planes. Rather, they’re being used to search a fire’s outer edges and providing intelligence that can help establish stronger fire lines.
“We’re taking what we’re learning and creating a guide for other agencies, like BLM (Bureau of Land Management) or other national parks to create their own programs,” Jager said. “I think they can all benefit from adding this tool.”
Grand Canyon National Park is the only park with its own fleet of unmanned aircraft that can be used for locating people who have gotten lost, stranded, injured or killed. Under a program that began last fall, it has five drones and four certified operators, the Associated Press reported.
The drones are about 18 inches across and 10 inches high, with a battery life of about 20 minutes. Drone operators watch the video in real time and then analyze it again at the end of the day.
As fire season revs up, so will conversations about the crossroads of the devices and wildfire. While crews have successfully used drones for recon and to aid in igniting prescribed burns, it’s only a matter of time until a curious hobbyist — once again — flies too close to firefighting operations.
The U.S. Department of Transportation’s Federal Aviation Administration (FAA) has come out in the past supporting the U.S. Department of the Interior and U.S. Forest Service in their simple message to drone operators: If you fly; we can’t.
“Flying a drone near aerial firefighting aircraft doesn’t just pose a hazard to the pilots,” said U.S. Transportation Secretary Anthony Foxx. “When aircraft are grounded because an unmanned aircraft is in the vicinity, lives are put at greater risk.”
That didn’t matter. After a string of incidents last year, the FAA warned in a mass email to recreational drone operators that those “who interfere with wildfire suppression efforts are subject to civil penalties of up to $27,500 and possible criminal prosecution.”

Firefighters battling the 46,954-acre Sawmill Fire 23 miles southeast of Tucson have been able to slow the spread over the last two days in spite of strong winds. Satellite imagery from early Friday morning did not show any large concentrations of heat over the previous 24 hours. This does not mean the fire is out, and there is no doubt a lot of line building and mopup work still has to be accomplished.
For the last two days the Sawmill Fire has been most active on the northeast side where aircraft have been assisting firefighters on the ground to slow the spread.
A Red Flag Warning for strong winds is still in place for the fire area as well as most of southern Arizona and southwest New Mexico.
On Thursday the Arizona Department of Transportation reopened Arizona Highway 83 south of Interstate 10.
The Pima County Office of Emergency Management has lifted the pre-evacuation order for residents on the west side of Arizona Highway 83. Residents in the Hilton Ranch area remain under pre-evacuation notice. An evacuation order remains in place for Rain Valley.

(UPDATED at 9:10 a.m. MDT April 27, 2017)
The growth of the Sawmill Fire east of Green Valley, Arizona slowed Wednesday as decreasing winds allowed air tankers and helicopters to drop water and retardant to assist the firefighters on the ground. The only significant spread that we found on satellite images was an additional 400 acres on the northeast corner of the fire.
As of Wednesday night fire managers were still calling it 40,356 acres.
An evacuation order remains in place for Rain Valley. Since evacuation orders were lifted for Greaterville and Singing Valley, residents of those areas are being allowed through the Arizona Highway 83 closure to access their homes. Arizona Highway 83 remains closed to public traffic.
The area is under a Red Flag Warning on Thursday and Friday for relative humidities in the teens and strong winds. One of the priorities on Thursday is to use aircraft to help secure the firelines before the winds increase.
Today, April 27, a Type 1 Incident Management Team will assume command of the 606 personnel on the Sawmill Fire.

At about 2 p.m. MDT the Incident Management Team said the Sawmill Fire had grown to 40,350 acres. At that time there were seven helicopters and three fixed wing aircraft assisting the firefighters on the ground.
On Wednesday morning the incident management team called it 20,000 acres.
At 2:03 p.m. MDT on Wednesday a heat detecting satellite mapped growth of the fire on the south and northeast sides.
The weather station near the fire at Empire recorded on Wednesday a high temperature of 75, a minimum relative humidity of 12 percent, and wind in the afternoon out of the northwest at 8-12 mph gusting at 20-24.

A fire that started Sunday morning, April 23 eight miles east of Green Valley, Arizona, has burned (we estimate) about 28,000 acres as of 2:38 a.m. MDT on Wednesday, April 26, 2017, and required evacuations for the communities of Greaterville, Singing Valley, and Rain Valley. It has spread to the east 21 miles, has a perimeter of approximately 63 miles, and crossed Arizona Highway 83 in multiple places.
The fire is burning on lands protected by the Coronado National Forest, Bureau of Land Management and the Arizona Department of Forestry and Fire Management.
On Tuesday the temperature in the fire area was in the low 70’s, the relative humidity was in the 30’s, and the wind was 12-18 gusting at 25-33 mph out of the west. The forecast for the fire area on Wednesday calls for conditions that could lead to significant additional fire spread toward the east and southeast, with temperatures in the mid-70’s, humidity dipping into the single digits, and winds out of the northwest at 10-20 mph gusting to 29.
Tuesday evening Jeff Andrews’ Type 2 Incident Management Team assumed command. Due to the increasing complexity, management will transition to a Type 1 Team on Thursday, April 27.
A full suppression strategy is being employed to protect nearby values at risk including homes, ranches and outbuildings, communications facilities, power lines, and the Arizona National Scenic Trail.
