Rancho Bolsa de Chamisal was a 14,335-acre (58.01 km2) Mexican land grant in present-day San Luis Obispo County, California given in 1837 by Governor Juan B. Alvarado to Francisco Quijada.
Cordero was granted the one and a half square league Rancho Cañada de Salsipuedes in 1844.
In 1846 Pedro Cordero sold his share of Rancho Bolsa de Chamisal to Lewis T. Burton.
Lewis (Luis) T. Burton (1809–1879) of Tennessee came overland with the Wolfskill party to California in 1831 and arrived in the Santa Barbara area shortly thereafter to trap otter.
With the cession of California to the United States following the Mexican-American War, the 1848 Treaty of Guadalupe Hidalgo provided that the land grants would be honored.
