Monica (together with the canyon, bay, mountains, boulevard, airport and freeway) is named for a natural feature not actually within its borders. The name for the springs has since reverted to Kuruvungna ("the place where we are in the sun"), which is what the Tongva People have called them all along. The springs remain sacred to the Tongva People. 1870s Government sovereignty in California passed from Mexico to the US on February 2, 1848. The northern sections of the city of Santa Monica once belonged to Rancho San Vicente y Santa Monica and Rancho Boca de Santa Monica. The Sepulveda family sold of Rancho San Vicente y Santa Monica for $54,000 in 1872 to Colonel Robert S. Baker and his wife, Arcadia Bandini de Stearns Baker. Bandini was the daughter of Juan Bandini, a prominent and wealthy early Californian, and was the widow of Abel Stearns, once the richest man in Los Angeles. Baker also bought a half interest in Rancho Boca de Santa Monica. Nevada Senator John P. Jones bought a half interest in Baker's property in 1874. Jones and Baker subdivided part of their joint holdings in 1875 and created the town of Santa Monica. The town site fronted on the ocean and was bounded on the northwest by Montana Avenue, on the southeast by Colorado Avenue and on the northeast by 26th Street. The avenues were all named after the states of the West, the streets being simply numbered. The first lots in Santa Monica were sold on July 15, 1875. Jones built the Los Angeles and Independence Railroad, which connected Santa Monica and Los Angeles, and a wharf out into the bay. The first town hall was a modest 1873 brick building, later a beer hall, and now part of the Santa Monica Hostel. It is Santa Monica's oldest extant structure. The southwestern section of the city originally belonged to the Rancho La Ballona of the Machado and Talamantes families. Mrs. Nancy A. Lucas purchased from the rancho in 1874 for $11,000. The property was farmed by her sons, and a parcel of was sold to Williamson Dunn Vawter for subdivision in 1884. 1880s Business started springing up. The town's new business district was initially centered around the current Third Street Promenade. Early street names consisted of both numbers and the names of western states; however Utah eventually became Broadway and Oregon became Santa Monica Boulevard.
