Previous research indicated that this small, rural complex was built sometime between 1909 and the early 1950's. Upon arriving there, I discovered a small engraving that read "A.D. 1939", so I can probably safely assume that to be the year of construction. I wasn't able to uncover too much information online, so I can't really give much history other than it was used as some sort of sewage treatment plant (indicated by some large text above the door), that it was abandoned quite a long time ago, and that it clearly suffered a fire at some point - possibly during the devastating 2017 wildfires. Unfortunately, the whole place has been completely cleared out and tagged to oblivion, but it was still a fun short explore. I'll include a mixture of phone shots and pics from my DSLR in this set, since the iPhone's wide angle mode does a pretty good job of capturing small spaces. Anyways, here's the photos...

A view of the structure from a nearby hill. That tiny building in the middle is the main thing that I explored, and I'm guessing the two round concrete structures once held sewage. If you look closely, you'll be able to see a rope that leads down into the open tank closest to the camera... I didn't try it!

I blurred out some potentially identifying info above the door. I'm not sure if this is overkill, but better safe than sorry.

Looking back at the front windows/door from inside the building.

Here's the wide-angle phone shots for a better perspective of this room. Visible in the above image is an open doorway leading to the outdoor area shown below.

A bonus shot from the main room that I kinda liked.
