Along Pacific Coast Highway just north of the mouth of the Russian River (150°)

Russian River: The river takes its current name from the Russian Ivan Aleksandrovich Kuskov of the Russian-American Company, who explored the river in the early 19th century and established the Fort Ross colony 10 mi (16 km) northwest of its mouth. They called it the Slavyanka River (Славянка), meaning "Slav River". The Russians established three ranches near Fort Ross, one of which – the Kostromitinov Ranch – was along the Russian River near the mouth of Willow Creek.
