Rancho Atascadero

Rancho Atascadero was a 4,348-acre (17.60 km2) Mexican land grant in present-day San Luis Obispo County, California.

[2][3] The one square league grant was from the secularized holdings of Mission San Miguel Arcángel.

[4] 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.

[7] A second claim was filed by Maria Antonia Ortega in 1853, but was rejected by the Commission due to lack of evidence of a grant.

In 1912, Edward Gardner Lewis, a successful magazine publisher, bought Rancho Atascadero from J.H.
