At the top of the ridge to the east sits the landmark Dos Piedras, erroneously translated as "two rock," between whose rocks ran the main Indian trail from Bodega Bay to the inland valley and to the Sierra. The rocks also mark the near juncture of four original Mexican land grants: Blucher Rancho, Rancho Roblar de la Miseria, Rancho Balsa de Tomales, and Rancho Laguna de San Antonio. To the south, the village of Two Rock, once the site of a Spanish cantonment, had its own post office and railroad station until the middle of the 20th century and remains the geographical center of a friendly and close-knit community of ranchers and dairymen.
