It lies northwest of Smartsville, at an elevation of 397 feet. Timbuctoo was once the largest town in eastern Yuba County. Situated strategically on the Yuba River near its gold-bearing sandbars, yet perched high enough into the river's surrounding hills to escape flood risk, the town enjoyed its heyday in the 1850s. Founded by the gold miners working the nearby river placer deposits, the town enjoyed further success with the introduction of hydraulic mining in 1854. Unlike many of the mining camps that amounted to little more than tent shantytowns, the wealth flowing from Timbuctoo allowed for the construction of permanent buildings of wood and brick. Aside from the usual stores and businesses, the town's amenities included a Wells Fargo office, saloons, a church, hotels and a theater. The town was founded in 1855.
