Sunset on Rodeo Beach, located in the Fort Cronkhite area of the Marin Headlands, one of the most special places in the Golden Gate National Recreation Area with access to multiple trails, fantastic views, a dog-friendly beach, fascinating geology, and an interesting history. As a pocket beach, Rodeo Beach sands do not migrate up or down the coast. Instead, they are carried a short distance offshore in winter, tumble about in the surf, and then return to replenish the beach in the spring and summer. Thus, the sands of Rodeo Beach are native to the Marin Headlands and reflect the Franciscan geology of the closest hills and cliffs. This earthcache focuses on the abundant radiolarian chert and rare carnelian pebbles.
