Rancho Bosquejo (also called "Lassen's Rancho") was a 22,206-acre (89.86 km2) Mexican land grant in present-day Tehama County, California given in 1844 by Governor Manuel Micheltorena to Peter Lassen.[1] The name means "Wooded Ranch" in Spanish. The grant extended along the east bank of the Sacramento River south of Rancho Rio de los Molinos and Toomes Creek, and encompassed present day Vina on Deer Creek.[2]
