Just below that, between the Southern Pacific and Union Pacific rail lines is "Swan's Subdivision." Henry A. Swan has been mentioned before in this blog concerning property he owned further south within lower Tonner Canyon. The Swan tract appears to be west of Brea Canyon Road within Walnut and City of Industry.
Sections four, nine and sixteen, meanwhile, were ranch lands of Alvin T. Currier, a Los Angeles County sheriff and state senator, who bought his property in 1869. About forty years later, he built a large home that was moved, several years ago and at great expense, by the City of Industry to the Phillips Mansion historic site in Pomona as Industry was developing the old Currier Ranch between Valley Boulevard, the 57 Freeway, Grand Avenue and the 60 Freeway.
But, the biggest landowner shown on the map, in parts or all of ten sections, was Frederick E. Lewis, who created the Diamond Bar Ranch. Note on sections 16 and 20 that two oil companies were leasing from Lewis, including Gold Seal Petroleum Company and Copa de Oro. There is an Olinda Village street by that name, though it is not known if there was a direct connection between the firm and the naming of the street four decades later.
Another curious detail is in sections three and ten, where a rectangular parcel set at an angle was used as the "Pomona City Sewer Farm"! This appeared to have been somewhere just east of today's 57 Freeway near Grand Avenue.
There are only a few oil well sites in this portion of the map. One is referred to as the Currier well at the lower left of section nine. Another, at the lower right of section sixteen, is a Gold Seal site. The third, at the upper right of section seventeen, is labeled "Fundenberg Well." This refers to W. F. Fundenberg, a Pennsylvania man who owned most of Tonner Canyon at one time (an earlier blog post discusses him in some detail) before it was sold and became Tres Hermanos.
Next another close-up or two (including more on Tonner Canyon) of this fascinating and richly detailed map from nearly eighty years ago.
