Telegraph Pass Trail
1875 Army telegraph route over granite peaks
Built by the U.S. Army in 1875 to connect Fort Yuma with mining operations in the Gila Mountains, Telegraph Pass cuts through some of the Sonoran Desert’s most unforgiving terrain. The route climbs over a 1,200-foot pass between jagged granite peaks, past abandoned mine shafts and the remains of the original telegraph line that gave the trail its name. Rock cairns still mark the way through boulder fields where wagons once struggled.
This is expert-level technical terrain requiring full armor and recovery gear. Granite boulders, loose scree, and steep grades demand careful line choice and experienced spotting. Summer temperatures exceed 115°F regularly, making this strictly a winter trail. No water sources exist along the route, and cell service is nonexistent. The reward is complete solitude in one of Arizona’s most historically significant and technically demanding corridors.
