Discovery Well
Shell Oil Company – Alamitos No. 1
June 25, 1921.

One of the world’s most famous wells, Alamitos No. 1, was started on March 23, 1921, and completed June 25, 1921, at a depth of 3,114 feet, flowing 590 barrels of oil a day.

This discovery well led to the development of one of the most productive oil fields in the world and helped to establish California as a major oil producting state.

This monument commemorating Alamitos No. 1 is a tribute to the petroleum pioneers for their success here, a success which has, by aiding in the growth and expansion of the petroleum industry, contributed so much to the welfare of mankind.
