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.
A river of fog rolls over the Golden Gate Bridge near Battery Spencer in California. Battery Spencer is about eye-level with the top of the north tower of the Golden Gate Bridge. Back during the early 1900’s, Battery Spencer was one of the main protection points for the San Francisco harbor. It featured multiple 12” guns that were manned by the military and a few buildings for housing the generators and shells. It was operated on and off until World War II when a lot of it was scrapped for war efforts. A “Low Fog Event” or LFE as its often referred to in the San Francisco Bay Area is when the fog is laying so low around the Golden Gate Bridge that you can see the top of the bridge towers peaking out above it.
