Tiburon is an incorporated town in Marin County on the Tiburon Peninsula, which reaches south into San Francisco Bay, and it is the nearest mainland point to Angel Island. The name derives from the Spanish word tiburón, meaning shark, and the incorporation was final on June 23, 1964. The rig crosses the valley from the foothills for repairs and fabrication at homes, docks, shops and jobsites across Tiburon.

John Reed received a provisional grant for much of southern Marin, including the Tiburon Peninsula, from the Mexican authorities in 1831. Later the San Francisco and North Pacific Railroad built a terminal here to connect with ferries of San Francisco Bay, and codfish canneries sprouted along the bay shore to can fish shipped from Alaska. Boat trailers, dock carts and pickup racks get repaired right where they sit, because the rig carries engine-drive welding power, wire feeders, an oxy-acetylene torch and a plasma cutter.
For directions, a landmark helps: Main Street, Blackie's Pasture, Old St. Hilary's on the hillside, or Paradise Beach County Park.
