The Ghost Town Above Rancho Cucamonga

While walking along my favorite walking trail today I got bored and took a left-turn off the electrical line service road and stumbled upon quite a surprise!  A complete little ghost town, or "ghost neighborhood"!

This this little ghost town is in the hills above Rancho Cucamonga, a few miles north and just east of Los Osos High School, about midway between the North Etiwanda Preserve on the East and the dam/spillway above Milliken Avenue on the West.  I have walked this trail literally 200 or more times in the last few years and had no idea these old houses or structures were here!  Because they sit low in the canyon you have to be above them to get a view, although I have been to the top of both the Milliken Avenue Dam/spillway and the Day Creek Dam and still never saw them.

The structures appear to be either houses or maybe some sort of old Ranger type stations or perhaps some kind of buildings related to water collection efforts for Rancho Cucamonga from over 70 years ago.  I found three structures (took pictures of two of them) and when looking at the area using the Google Maps for this post, I spotted what might be a fourth building hidden in the brush and several more structures to the south.

What I call "structure #1" is the most interesting.  It's nothing more than a fireplace, but it has a stamp that reads "Built For CG.1346 CCC F.L. Graves 1934".  I was not able to find anything on the internet about "F.L. Graves", but I am assuming that the "CCC" is for "California Conservation Corp".  The date leaves no guessing - it was built in 1934, making this structure (and probably the others) almost 80 years old.

Structure #2 is about 1/8th of a mile south of structure #1 and has a similar fireplace.  However this structure has a rather large foundation, and another structure made of cinder-block a few feet away.

The third structure (no pictures) was about 1/8th of a mile east of structure #1 and was nothing more than pieces of a foundation and a wall up against the side of the hill.  There was also the remains of a rusted-out car about 100 feet to the south on what looks like was once a road.  There was not enough left of the car for me to figure out what model or year it was, but it looked like it could have been a station wagon from the 1960's or 1970's.

I didn't see structure #4 while I was there and only discovered it while writing this post.  You can click on the satellite image to get a Google Map of the exact location. (Lat & Lon: 34.171173, -117.559163)

There also appears to be a whole string of other structures (not shown on the map) just to the south that I plan on exploring next.

 

If anyone has any information about what these buildings might be or who "F.L. Graves" was, please post a comment.

Wow amazing! What did the letters say? Can you share please!!

Can you scan and post the letters please? That's an amazingly wonderful connection to the history of this area that is seemingly lost. Please consider ! Thanks!:)

I thought the Ranger Station was located at the top of the large outcrop/mound that is now called the "Panoramic Viewing Area" in the North Etiwanda Preserve. At least that is what I always believed. We drove to area in a car in the 80's and there was still a large foundation at the viewing area and the area was littered with shells/casings and broken clay pigeons back then. I don't think we even noticed the CCC camp. The camp's outline is very clear in Google's current imagery. Perhaps the fire made it easier to see.
