Thats pronounced like a horse pen not a reef critter.

There is a report in the Tracy Historical Society that the quality of the coal was very poor. Trains running from Tesla to Stockton had to stop near Lathrop to empty the ashpan on the steam locomotive, because the coal had too much ash content. As soon as someone (possibly at Union Oil of California) invented the oil burner that sprayed a mist of oil into the firebox, all California railroads switched from wood or coal to oil. The Associated Oil Company (Flying A) was owned by the Southern Pacific and Santa Fe railroads. That's where they got the oil for the steam locomotives. When Western Pacific Railroad was building west in 1910 from Salt Lake City to California they bought the Alameda and San Joaquin Railroad which is still used today from Tracy to Stockton as part of the Union Pacific railroad. The Tracy depot was named Carbona after the Tesla coal mines.

Fascinating, thanks for making this. I'm 80 years old life is short.

I had competed in cycling road race in that area (Patterson Pass and Corral Hollow), and never knew there's once an old mining town. Thanks for bringing this up. I now know a little bit more about the areas I've visited in California.

Finished high school in Livermore was always out there at Carnegie off road park has friends that lived nearby and never knew anything about the history of the area. Thank you for the insight blows my mind and crazy it was never taught to us in school back then.

Tesla is now home to a huge PG&E sub station. Thanks for the tour.

Born and raised in Tracy 9 miles to the North. We would explore those old mine shafts back in the 70s. Too bad they closed. It the old ladders were getting rickety even then. Great Drone Shots! Thanks!!

Nice video. The Narrow Gauge and Shortline Gazette (a model railroad magazine) had a nice article on the Tesla railroad many years ago. Article included a number of good photos from the time Tesla was active.

Interesting video on this area. I had come across the Tesla quad and did not know of the history of the town. I did some quick internet searching and looks like the coal maybe coming from the Eocene age Domengine and Nortonville formations which I understand produced low quality coal (sub-bituminous or lignite) These rock units outcrop further north and are now in the Black Diamond Mines Regional Preserve.

My great aunt was born in Tesla in 1900😊 Thank you for the history and the book recommendation.

Love you content you are a great story teller great pictures of past and present thank you for the adventure 🏆⛏️🇺🇸

That area should have a historical monument for travelers to enjoy and learn from.

Just found this and loved it! Looking forward to seeing more.

That area was going to be added to the nearby motorcycle park 20 years ago. The state said no to all access. I got to hike the place with my son, but the next time I went along the river with my GF I noticed a camera and it started to blink. Rangers came speeding up and gave us the boot. Worth seeing regardless.

Just brought your video to 700 likes. Good video; good historian job!

New subscriber after discovering your channel last night. Really enjoy your content and presentation of the history of these sites. Keep up the great uploads!

Fascinating

Thanks for making this, im born and raised just off mt hamilton rd and never knew about any of this history

I thru cycling heard of Coral Hollow in the 80's but never went there . Now I know . Nice commentary... Thanks !

That was great, well put together. ......thank you

What a fantastic video! Thank you, California Whistlestop. Those interested in visiting a similar (low quality) coal mining area not far away should plan a visit to Black Diamond Mines Regional Preserve where much access is still provided by the East Bay Regional Parks. As with Tesla, everything that was made of wood has burned down over the years. There is however a fascinating graveyard, interpretation centers are provided, extensive hiking, picnicking and (limited) camping are available. Cumberland it never was, but there also was a high-quality sand mine there.

It would be helpful if a cursor could be used to point to the areas being described. Nice presentation, thank you for no annoying music.

Quite a well done presentation! Kept listeners interested all along the way. Thanks

Cool video you should make a video on Preston California or zim zim California

Great video!

I commuted Tesla road for many years and never heard of this. Thanks for the video and great job 👍. I think there was a gold mine on the corral hollow side to the east.

Wow, really cool video, very different, thankyou :)

Well done video. From the first view that you showed of the area, I suspected a flood had washed through there at least once. Good Luck, Rick

That would be the Narrow Gauge and Short Line Gazette , May/June 2001 and two follow ups

The black and white photos of Tesla were taken from Dan Mosier book ‘History of Tesla - A California Coal Mining Town’ , 1998

I wrote three articles in 2001 about the Alameda and San Joaquin railroad Tesla and the coal bunkers in Stockton , for Narrow Gauge Shortline magazine. The real expert is Dan Mosier ,r he wrote a book on the history of Tesla a local resident Renée Lueckfeld as a teacher in Livermore district She has compelling history on Tesla.

Very well done. Where was the railroad located? What it roughly on top of where Tesla Road is today?

Interesting video. I lived in the Tri-Valley for 40 years and never heard of Tesla. There were quite a few abandoned coal mines along those hills and they've cost taxpayers a pretty penny to close all the portals and clean up the mess. We did a job to close one of the portals near (I think) Clayton back in the '80s. Had to helicopter in the concrete.

Been intresting to hear thickness of various beds. I forget now what the minimum economic thickness is, but have always thought a robot miner that could dig a 4 inch seam would make millions

Great video but it's not cor-ul like you find in the ocean. It's cor-al like where you keep horses.

Good history piece. Just a fussy language challenge: what's the difference between "mining" and "mining operations."

That's cool, who owns the property now?

I didn’t realize this KZfaq channel was only for speed readers

Is the mine played out or did the epa kill it?

Thanks for the boiler plate lecture at the beginning, but you are preaching to the choir; it is of no benefit to us good hearted people and the ones that vandalize will ignore it with prejudice. ?A clay company in competition with a coal company?? How does that work?

Yeah, well the rest of California isn't abandon any where livable less and less places to find.

Good think natural came back whoever owns this land protect land don't let the human garbage come and take the resources

Great video !
