Rancher
Lassen was granted the 22,206-acre (8,986 ha) Rancho Bosquejo Mexican land grant in Tehama County, California by Governor Manuel Micheltorena in 1844. On his third expedition to the west, John C. Fremont recorded in his journal that in the spring of 1846 he visited and stayed at the Lassen ranch, noting that Lassen had brought into cultivation wheat, grapes and cotton. In 1855 Lassen moved to the Honey Lake region, where he prospected and served as Surveyor and Governor of the unofficial Nataqua Territory.
