A wildfire started by a Sunday evening lightning strike on Mount Lemmon was mostly contained after burning 240 acres, Coronado National Forest officials said Tuesday.

The Prison Fire, which started near Molino Basin relatively low on the mountain, was 50 percent contained thanks in part to 0.65 of an inch of rain that fell in the area Monday evening, Coronado officials said in a press release.

The fire burned in part of the area that was scorched 10 years ago by the Aspen Fire, which burned 85,000 acres and destroyed much of the mountaintop village of Summerhaven.

Another Coronado fire, burning along the U.S.-Mexican border nine miles east of Nogales, was reported 95 percent contained Tuesday, also thanks to heavy monsoon rainfall, forest officials said.

The border fire covered 530 acres on both sides of the line. It started Friday and while the cause has not been determined, forest officials said it likely was from human activity.
