Zodiac is a famous El Capitan aid route on the southeast face. It is known for steep, sustained aid climbing on clean granite with significant exposure. The route is a classic big-wall objective and is commonly climbed over multiple days. It is documented in Yosemite big-wall guidebooks and climbing literature. Hazards include rockfall, weather, and the commitment of being high on a large wall. The route is not a mountaineering snow or ice climb, but a technical alpine-style rock route.
