The History of the city of Glendora, California
This part of California has been inhabited for over 10,000 years, read more about the early history of this area in History of Azusa.
The first settlers were the families of Fecundo Ayon and Gregorio Fraijo during the 1850s. The railway was built through this area in 1887 when a subsidiary of the Santa Fe Railroad linked its main line in San Bernardino with Los Angeles.
The post office opened in 1899.
Irwindale, the name
The town which finally incorporated in 1957, and was chartered in 1986 was named after a local citrus Grower.
It was an open area, beyond the city limits of Azusa to the east and Duarte to the west, beyond the San Gabriel River. In fact, there is no reference about Irwindale in any of the early maps or accouns of the region:
The USGS survey along the Santa Fe railroad of 1915 says the following: "Two miles west of Azusa the train crosses San Gabriel Wash, the bed of San Gabriel River, the largest stream flowing from the San Gabriel Mountains. The canyon through which the San Gabriel emerges from the mountains is in sight about 3 miles northeast of the trestle over the wash. During the rainy season San Gabriel River is a stream of considerable size, furnishing water for irrigating many citrus groves and other orchards and fields on the slope south of the mountains. During the dry periods it dwindles to a mere brooklet, even within the canyon.".
National Old Trails Highway (N.O.T.) in Irwindale
By 1915, use of the automobile had grown considerably and the National Old Trails (N.O.T.) Association had been formed to promote a highway link between New York and Los Angeles. The road was build along the Santa Fe railway. In 1912 map by the Automobile Club of Southern California published a map which shows Azusa (26 mi. from LA), where the road crossed the S. Fe railroad and to the west was Duarte, no signs of Irwindale.
1926: Route 66 in Irwindale
Route 66 was created in 1926 and it used the alignment of the N.O.T. highway here, and has remained on this alignment until 1964 when it was bypassed by the freeways.
Two road maps of Los Angles (1935 and 1939), show Route 66 running between Azusa and the San Gabriel River along Center St. and no other town until Duarte. The same is shown in a 1940s map where San Gabriel Wash has no town next to it.
The "Guide to the Golden State" written by the WPA in 1939, described the Irwindale section of Route 66 as follows:
"... AZUSA, 27.6 m. (611 alt., 4,808 pop.), dating from the boom year of 1887, is vet another citrus-shipping center. The name is derived from Asuksag-na, name of an Indian village here.
The name of DUARTE, 31.9 m. (600 alt., 1,326 pop.), center of an old orange-growing district, commemorates Andreas Duarte...."
Jack Rittenhouse about this segment west of San Bernardino to Pasadena mentions a list of towns: "... AZUSA, 343 mi., DUARTE, 347 mi.; MONROVIA, 350 mi., and ARCADIA, 352 mi....", so there is no refrence to Irwindale until the 1950s.
The town began to grow when the demand for road paving led to the development of the rocks in the area as a source of crushed rock and gravel as wel as sand. Hence the City of Irwindale's nickname as "Jardín de Rocas" which is Spanish for "City of Rocks".

Jardin de Rocas
Irwindale lies next to the great San Gabriel "Wash" a temporary river which over thousands of years, whose water during the rainy season has eroded the San Gabriel Mountains and deposited sand, gravel and rocks in the lowlands.
This barren land would be the source of the city's wealth as road building in California demanded rock and gravel. These rock quarries are a major source of income for the city and you can see them to the north of Route 66. There are 17 gravel and sand pits in town.
Route 66 runs through a narrow part of the city, and is only half a mile long here (800 m), there are no striking Route 66 classics in Irwindale, just a great view of San Gabriel mountains as you cross the Route 66 bridge into Duarte.
