Rancho Bolsa de Tomales was a Mexican land grant in present day Marin County and Sonoma County, California given in 1846 by Governor Pío Pico to Juan Nepomuceno Padilla. The name means "the Pool of the Tomales Indians," which referred to Burbank’s Lake. The grant extended along the Pacific coast from Estero de San Antonio south to Walker Creek, and encompassed present day Tomales. Stemple Creek transversed the property. The land claim was rejected as fraudulent by the US Supreme Court.

Stemple Creek is a 16 mi (26 km) long, westward-flowing stream in the California counties of Sonoma and Marin, which feeds into the Estero de San Antonio. Its waters ultimately reach Bodega Bay, part of the Gulf of the Farallones National Marine Sanctuary on the Pacific Ocean.

Nick's Cove is the site of a long-standing restaurant and vacation camp in Marin County, California. It is on the northeast shore of Tomales Bay 3.25 miles (5.2 km) south-southwest of Tomales, at an elevation of 7 feet (2 m). Hog Island is in the middle of Tomales Bay, to the west of Nick's Cove, and Point Reyes National Seashore constitutes the western landmass on the opposite side of the bay. The name honors Nick Kojich, who in 1931 opened a seafood restaurant at this location, which is still in operation.

Hog Island is an island roughly 2 acres (0.8 ha) in size located approximately 5 mi (8 km) south of the entrance to Tomales Bay in the West Marin area of Marin County, California. While waters to its west are deep enough for small ships to enter Tomales Bay, at low tide the shallows to the east may be wadeable to the eastern shore of the bay. Unsuspecting vessels have run aground in that region a number of times. However, as it is some distance from the mouth of Tomales Bay, Hog Island does not experience the large sudden waves that characterize the Tomales Bay Bar entrance region.The name Hog Island reportedly came from a wild 1870s incident, in which a barge carrying a load of pigs caught fire and was grounded on the island to avoid sinking—at which point the pigs escaped onto the island until they were rounded up again. The island lends its name to the Hog Island Oyster Company, which produces shellfish on Tomales Bay, several miles south of Hog Island. The San Andreas fault runs through the center of Tomales Bay, past Hog Island. Local legend claims that Hog Island and nearby Duck Island (also known as "Piglet") were once connected, but separated as a result of the 1906 San Francisco earthquake. While land deeds from the 1880s indicate that the two islands were separate before the earthquake, the two islands are (and have been) intermittently linked by a sand spit exposed at low tide. The Inverness Yacht Club hosts an annual sailboat race around the island. Competing boats sail from the club, around the island, and back to the club again.

Rancho Blucher was a 26,759-acre (108.29 km2) Mexican land grant in present day Marin and Sonoma County, California given in 1844 by Governor Manuel Micheltorena to Jean Jacques Vioget.
