Flames and smoke from the Spud Rock Fire, burning more than 300 acres, drifts over the Rincon Mountains east of Tucson, Ariz., August 19, 2020.

Two lightning-sparked wildfires burning in the Saguaro National Park's Rincon Mountains closed two campgrounds and a host of trails on Saturday, officials said. 

The Manning Camp and Spud Rock campgrounds have closed due to the Spud Rock and Mica Bowl fires burning for the past week.  

Park officials say the Spud Rock Fire has grown to approximately 360 acres by Saturday afternoon. It's burning ponderosa pine and timber with “creeping growth” in all directions.

Crews are working to keep the blaze east of the Arizona Trail and other trails by scraping down the areas to bare mineral soil to prevent its spread.

They are expecting less fire activity with rain forecasted for the weekend.

“Challenges include extreme heat and logistical complexities associated with supporting firefighters with food, water, supplies, and medical response while working in remote areas,” officials said. “Firefighters have used both pack mule strings as well has helicopters to shuttle staff and supplies to the Manning Camp.”

Firefighters are also monitoring the 26-acre Mica Bowl Fire, which is producing minimal activity, burning between a mountain drainage and rocky outcropping.

“Taking advantage of these natural holding features is generally the most effective, safest, cost-efficient tactic. It also minimizes impacts in the Saguaro Wilderness,” park officials said.

The following trails are closed due to the fires:

â€ĸ Heartbreak Ridge

â€ĸ Turkey Creek

â€ĸ Deerhead Spring

â€ĸ East Slope

â€ĸ Devil’s Bathtub

â€ĸ Mica Meadow

â€ĸ Bonita

â€ĸ Fire Loop

The Arizona Trail remains open, but for safety concerns, “segments may be subject to short notice closure or hiker escort through the area, dependent upon fire activity,” park officials said.

Smoke will remain visible to residents in the Tucson, Redington Pass, Vail, Mescal, and the surrounding area.
