I believe, but can't prove, this is Stringfellow Acid Pits in Jurupa Valley, California. If correct, it was a property with about 11 unlined ponds used to dump waste acids and other bad stuff. It was closed in 1972 when traces of waste were allegedly found in a nearby water district's wells.

It's a visual shock to see materials handled like this in the United States.

I hope the photographer was upwind.

This was before the Department of Transportation had standardized placarding on trucks hauling various materials. Nowadays, there are placards on trucks that correspond to a Emergency Response Guide book. Truck on fire? Here's what you need to know...

I remember seeing acid waste sumps at various enterprises. The local District Attorney's crime laboratory had an acid waste sump.

I see a Peterbuilt emblem on the cab and think this tractor is a late 1950s 352. Feel free to correct me if you see something different.

I think the B over E logo means the crane is made by Bycrus Erie. Comments welcomed.

Must've been quite a strobe to get this photo.

Brands of vehicles cannot be identified by me because of low resolution photo.

Chuck Walla I replaced it with the original photo

Based on the vehicles, my guess is this was shot in the early 1950s. There are two Chevrolet ~1948 cars in the center of the front row. They have an interesting assortment of material handling vehicles.

I see a wooden water tank at right of the crane and a flammable liquid tank at left of the large forklift.

Some vehicles appear to be 50- and 60-series made by Cushman.
