A lightning-ignited fire was reported Wednesday, July 19, 2017, in the Rincon Mountains at approximately 3:15 p.m. It is located about 1/2 mi NW of Spud Rock (correction due to better mapping). The fire is estimated to be approximately an acre.

Firefighters are currently monitoring and assessing the fire. Fire behavior is currently low, dampened by humidity and recent rain. There’s a chance of additional precipitation in the coming days. Firefighters will continue to monitor the fire and take action as needed.

The fire is burning within the Saguaro Wilderness at an elevation of approximately 7,000 feet (correction due to better mapping). It is burning in steep, rugged terrain. Vegetation in the area includes ponderosa pine. There are several rocky outcroppings in the area that will serve as natural fuel breaks. This area burned most recently in 2003 during the Helen’s 2 Fire.

The fire is in the vicinity of the North Slope and Fire Loop Trails, however no closures have been implemented at this time. Backcountry visitors are encouraged to check with the Rincon Mountain Visitor Center for current conditions and updates on potential trail closures.

Smoke is visible from Tucson, Redington Pass, and the surrounding area.

The Saguaro Wildland Fire Module is currently assigned to the incident. Cooperators include the Coronado National Forest.
