Photos: The Bighorn Fire burn scar in the Santa Catalina Mountains
The Bighorn Fire started on June 5, 2020, after a lightning strike on Pusch Ridge in the Santa Catalina Mountains inside Coronado National Forest east of Oro Valley. The fire raged through the entire mountain range, burning the front range down into Pima Canyon, Finger Rock Canyon, Esperero Canyon and upper Sabino Canyon. It continued into the drainage below Mt. Lemmon – Cargodera and Romero Canyons. It burned into the grasslands in the foothills north and east of the range. There was little left untouched. Thanks to the efforts of nearly 1,000 personnel, thousands of gallons of fire retardant and a little rainfall, the fire was declared 100-percent contained on July 23, 2020. It burned 119,978 acres.

With the road to Mount Lemmon closed for the summer, try some of these Southern Arizona outdoor destinations.
Forest Service officials say they're not sure if all the Catalina Mountains' hiking trails can be cleared of hazardous debris by Nov. 1, when their forest closure order is scheduled to expire. The dangers were caused by the Bighorn Fire.
Federal Aviation Administration said it couldn't prove that a drone operator it investigated was the actual operator of a drone that illegally flew into Bighorn Fire air space, seriously hampering firefighting efforts.
Most recreation areas between Tucson and Summerhaven were closed earlier this summer due to concerns about the potential for flooding and runoff following the massive wildfire.
The massive wildfire in the the Catalina Mountains burned about 120,000 acres over several weeks this summer.
The acreage torched by wildfires in Arizona was up sharply this year, but fire officials said it was still not a particularly bad season in te…
Top fire management official anticipates conditions this year will be no better than last year's, when about 980,000 acres burned in Arizona.
The governor joined state experts Monday to talk about wildfire danger expectations across the state.
The Pima County Sheriff's Department will monitor the amount of traffic going up the mountain and delays are expected.
The highway from Tucson to Summerhaven was reopened last week after a closure prompted by the massive Bighorn Fire. But the Coronado National Forest on Mount Lemmon remains closed to the general public.
Firefighters will hike into the areas on Saturday to assess the fires.
The road to Mt. Lemmon has been closed several hours while officials investigate a motorcycle crash Sunday morning.
The Westridge Fire, in the Tortolita Mountains northwest of Tucson near Marana and Oro Valley, stood at 480 acres on Tuesday.
The shuttle and the visitor center at the popular Tucson destination will remain closed, and restrooms and trash services are not available at all recreation areas.
Barely more than four inches of rain fell in 2020 in Tucson's official measurement, stressing desert plants and drying up already fragile streams including the area's showpiece, Sabino Canyon.
Wet weather last year and the predicted hot, dry spring and summer are the reasons. Plus, Arizona is having trouble hiring wildland firefighters.
