Riverside’s navel orange

From a recent edition of the Los Angeles Times:
The bronze plaque tells the tale: “The most valuable fruit introduction yet made by the United States Department of Agriculture.”
And there, at Magnolia and Arlington avenues in Riverside, stands the last of California’s original Washington navel orange trees, enclosed by an iron fence, looming over the plaque in the summer sun.
It is the tree that launched the storied citrus industry in the Riverside area, an industry that helped shape the world’s view of Southern California as a tropical paradise in the early 20th century.
Los Angeles Times – August 5, 2004

For those who don’t know, from this very navel orange tree (and a second sibling tree that died long ago) descended every Washington Navel orange tree in California, spawning California’s highly-successful — and very lucrative — navel orange industry. Some historians have referred to it as the second “gold rush” for California.

Gamble-Estudillo House -- Located on the edge of downtown, this Crafstman style California bungalow was built in 1911 for $8,500 by Riverside's Cresmer Manufacturing Co. from plans drawn up by architect Seeley L. Pillar (who also did the original Arlington Library). Original owner, Austin A. Gamble, helped establish the California Iron Works company with Fred Stebler. In 1918, the home was sold to Miguel Estudillo, a well-known Riverside attorney, state assemblyman and senator. The house remained in the family until 1971.
