# Event Details - **Event Name**: Bighorn Fire Erosion Control in the Catalinas (July 18-20) - **Event Start and End Date**: Fri, 18 Jul, 2025 at 03:00 pm – Sun, 20 Jul, 2025 at 06:00 pm - **Event Description**: Join us in the Santa Catalina Mountains for a weekend building erosion-control structures in areas burned by the 2020 Bighorn Fire.About this EventThe WorkWe will be creating loose rock structures to halt erosion, increase water absorption, and support plant growth in drainages off the control road in the Santa Catalina Mountains. These low-tech structures can make huge differences and are a great tool for transforming landscapes. We'll be getting dirty, bending, lifting, and digging with tools provided by SIA.What to Expect/BringFolks staying through the weekend should bring their own camping gear (or contact us if you need to borrow some) and meals for the weekend — a minimum of two breakfasts, two lunches, and two dinners, with snacks.SIA will provide potable water, and folks are welcome to bring their own as well. There is water at the campsite to refill from, but none at the worksite.Be prepared to unplug — there is limited or no cellphone or internet service where we'll be camping and working.Bring camping gear: tent, sleeping bag, sleeping pad, etc. We have extra camping gear available to borrow. Please contact our staff listed below if you would like to use some of our equipment.Bring work clothes, work gloves, and appropriate close-toed boots/shoes that you are happy to hike in and don't mind getting dirty or damaged.Bring sun protection: sunscreen, long-sleeves, hat, etc.Bring a refillable water bottle and a daypack for snacks and gear.We will be building rock structures, which will entail carrying, moving, and placing rocks of various sizes. Some heavy lifting will be required, though no one will be asked to lift more than they feel capable of, and folks can work in teams to move larger rocks using cargo nets. Be prepared for getting dirty as we will also be digging as part of the building process. We will also be hiking to our worksites, which may be up to two miles by trail from a trailhead (though likely closer), while carrying tools such as picks, rockbars, and/or shovels. Worksites may be steeply sloped and uneven, with the potential for loose footing. Also, in our search for building materials, we will be traipsing around off trail in rocky drainages and across slopes.LocationWe'll be camping in the Spencer Canyon Campground. We may drive or hike (<2 miles) to our worksite each day. Please note there will be on-site restroom facilities at the camping area, but not the work area.Getting ThereOur campsite in the Spencer Canyon Campground is along a dirt road, but is accessible by two-wheel drive and low-clearance vehicles.Option 1Meet at the SIA office at 3127 N Cherry Ave. at 2:45 p.m. on Friday to caravan or carpool to the campsite.Option 2If you would like to meet us at the camping area, please join us after 5 p.m. (directions to the campsite will be sent to registered participants).Option 3If you would like to meet us for the day on either Saturday or Sunday, please meet us at our campsite by 7:30 a.m. (directions to the campsite will be sent to registered participants).From Tucson (26 miles): Take Catalina Highway off Tanque Verde Road in Tucson.
