Well, Alamitos 1

Signal Hill, Los Angeles County · California
Erected by Shell Oil Company and The Petrolum Production Pioneers, 1952

The hill was chaparral and truck farms being subdivided for houses when Shell spudded a wildcat here on March 23, 1921. It blew in before dawn on June 23 at 3,114 feet, over the top of a 114-foot derrick, and a crowd of a few hundred was fifteen thousand by daylight. The hole caved and had to be cleaned out; the well was flowing about 590 barrels a day by the 25th. People who had bought lots to build on leased them for drilling instead, and the derricks went up with their legs crossing.
