April 22nd, 2021 | Hikers flock to the rugged Santa Catalina mountains north of Tucson, but many trails are still off limits in the wake of last year’s Bighorn Fire. Most trails remain closed within the burn scar of the 119,987-acre Bighorn Fire, which raged from June 5 through July 23. Some trails are within Pusch Ridge Wilderness on the southwest flank of the mountains, and others are north or east of the wilderness.
