The History of the city of San Dimas, California

This region of Southern California has been inhabited for the past ten thousand years. The natives encountered by the Spaniards when they explored California in the 1600s were known as "Tongva". The Spanish called them Gabrielino or Gabrieleño (after the San Gabriel Arcángel Mission established nearby in 1771 ).

The Mission owned a vast tract of land which it retained after Mexico became independent from Spain in 1821, but later had to give up during the "secularization" enforced by the Mexican government in 1837 when way Mexican Governor Juan Bautista Alvarado granted the land in 1837 to Ygnacio Palomares and to Ricardo Vejar.

Palomares and Vejar formed 15,000 acre ranch naming it "Rancho San José" which covered what is nowadays San Dimas, Azusa, Covina, Walnut, Glendora, La Verne, Claremont and Pomona.

Mexico lost California to the US after the 1846-48 war, and in 1850 California became a state of the Union.

After Palomares died in 1864 his widow sold the land and Vejar lost his part due to forclosure. The place at that time was known as "La Ciénaga" (Mud Springs).

The Atlantic & Pacific Railroad, which spanned the U.S. from Saint Louis to Barstow in California, and was a subsidiary of the Santa Fe Railroad, reached San Bernardino in 1885 and immediately set out to reach Los Angeles.

So its subsidiary, California Central Railway - CCR acquiered the San Bernardino & Los Angeles Railway and extended its line west from San Bernardino to Mud Springs -now San Dimas- in 1887 where it linked with the Los Angeles and San Gabriel Valley Railroad (also purchased by CCR) and proceeded via Pasadena into Los Angles through Arroyo Seco.

The area was developed by the San Jose Ranch Company in 1887, setting up a station there and changing its name to San Dimas after the local Canyon, north of the tracks.

The name: San Dimas

The town was named after San Dimas Canyon in the San Gabriel Mountains. The Canyon was named after Saint Dismas (in Spanish "San Dimas"), who was one of the two thieves crucified with Jesus and canonized by Christ himself. The name originated in Greece -Dimas King of Thrace was grandfather of Troyan heroes Hector and Paris.

The townsite was platted just south of the Way Hill (1,090 ft.) and it became the hub of a farming community that grew citrus.

The land bubble burst in 1889 and the hotel built near the station to house the settlers never lodged any. It was later purchased by the Walker family and is now the Historic San Dimas Hotel (also known as the Carruthers Home, Walker House and the San Dimas Mansion).

A marmalade factory and four citrus packing houses were located in the town.

The USGS survey along the Santa Fe railroad of 1915 says the following about the town and its surroundings: "... West of Claremont a spur of the San Gabriel Mountains on the north extends nearer to the railway, and the San Jose Hills, a northern extension of the Santa Ana Mountains, approach from the south. Owing to these conditions the valley narrows to about 3 miles at Lordsburg. In order to pass the San Jose Hills the railway has been deflected to the northwest, a course that soon takes itnear the foot of the San Gabriel Mountains, which are closely skirted from San Dimas to Pasadena.... North of San Dimas (dee'mas) a mass of sandstones and shales with interbedded volcanic rocks is exposed at the foot the mountains... halfway between San Dimas and Glendora, the train crosses the dry wash of San Dimas Creek, which heads in a large canyon a few miles to the northeast. It is a good example of a wash formed by a powerful intermittent stream.".

National Old Trails Highway (N.O.T.) in San Dimas

By then the use of the automobile had grown greatly and the National Old Trails (N.O.T.) Association was formed to promote a highway linking New York with Los Angeles. It was built bordering the Santa Fe railway and the 1912 map by the Automobile Club of Southern California's map shows the highway running from Claremont (38 mi. from LA) and then after some curves, it headed towards Glendora, crossing the tracks there (28 mi.), but it did not show San Dimas (though you can see the station next to the tracks south of the road.

1926: Route 66 in San Dimas

In 1926, the alignment of the N.O.T. highway became Route 66 in California. It ran along Foothill Blvd. which was widened into a four lane highway after 1931, by 1939 the "Guide to the Golden State" written by the WPA, described the San Dimas area as follows:

"... At 23.3 m. is a junction with San Dimas Canyon Rd. Right on this road to SAN DIMAS CANYON PARK [...] naturally wooded land (picknicking facilities) at the foot of the San Gabriel Mountains. Hiking trails lead into the mountains. The motor road winds up the canyon to WOLFSKILL FALLS, 11 m."

In the 1940s Caltrans road map, Route 66 goes through La Verne with a southeast to northwest course, and to the south of it, away from the road is "San Dimas". Then US 66 returns to its east to west course and enters Glendora, always along Foothill Blvd.

Jack DeVere Rittenhouse rode the whole of Route 66 and, in 1946 wrote his "A Guide Book to Highway 66" in which he says that the towns in this area "... are so close together as to be practically indistinguishable from each other..." adding "More towns you pass through include LA VERNE at 336 mi., GLENDORA, 241 mi.;..." not mentioning San Dimas.

By the 1950s, the citrus groves were affected by disease and many were uprooted, this made space for the growing Los Angeles suburbia. The freeway system was also expanding rapidly and by 1964, four years after San Dimas incorporated, I-10 replaced Route 66 as the main highway in the area.

Pinnacle Peak Steakhouse

269 W. Foothill Boulevard

There is a "covered Wagon" as an eye-catcher in the parking lot. A homage to kitschy Route 66 landmarks. The place is which opened in 1967, is a steak house (a simple place to eat ribs and steaks with no-frills).

It has an interesting rule: "NO TIES ALLOWED", which if not removed promptly, are cut off and hung from the rafters. So don't wear a tie!.

It covers 15,000 sq. ft. (1.400 m2) and had 18 bedrooms, 33 rooms in total, 14 fireplaces, a veranda and proch, cupola and balconies.

It was finished just as the land bubble burst so it never had a single paying guest. The San Jose Ranc Co., who'd built it, sold it in 1889 to James W. Walker, a wealthy merchant from Kentucky.

It remained in the family until the last occupant, Mrs. Raymond I. Carruthers (J. Walker's granddaughter), and her family leased it in 1979 and a restaurant (San Dimas Mansion) opened there, serving guests like Richard Nixon and John Wayne, but it closed in the 80s. The place was finally purchased by the City in 2000 and renovated the building, it now houses the San Dimas Historical Society and Museum and a community art gallery.

Downtown San Dimas: "Western Village"

Bonita Ave., San Dimas
