Erosion Control in the Catalinas
February 24, 2026Join us in the Santa Catalina Mountains for a weekend building erosion-control structures in areas burned by the 2020 Bighorn Fire. Together, we can protect springs from landslides and ensure the mountain absorbs even more rain and snowmelt, recharging the aquifer that plants, wildlife, and people like us depend on. Note: Carpooling from Tucson is available, and day-trippers are most welcome. We’ll be camping at Whitetail Campground on Mt. Lemmon.
