Mining Ruins, Riverside, California
The Standard Mine
The Standard Mine is a 600+ acre abandoned Gypsum Mine and processing plant. I saw the turnoff on the way to the Ghost Town of Midland. By the looks of the processing plant it probably hasn't been used since the 60s. Right next to the water tower, you can see the skeleton tracks marks of the old railway. The Standard Mine is another 9 miles past the processing plant and since it rained pretty hard the day before, I decided not to drive out and take a risk of getting stuck.
History of the Abandoned Railway:
In the mid-1920s, Midland was founded midway along the line to house the employees of the US Gypsum mine. There was no direct water line to Midland at the time, so a daily train carrying an average of 20 tank cars carrying water made its way between Blythe and Midland. The USG plant in Midland became a significant customer on the line, producing gypsum for several customers in the United States, most notably Fresno, California.
