Goleta Asphalt


If you know what you’re looking at, this boring clump of ivy holds a lot of historical importance. This is all that’s left of Goleta’s once booming asphalt industry.


In 1890, the Alcatraz Asphalt Company leased a 400-acre tract of land  that had a surface tar pit on it, from Augustus “Gus” Den. There were other asphalt deposits in Carpinteria and on the More Mesa, and they  had all been used throughout the years, all the way back to the Chumash. But Alcatraz would build the first mine to use deep shafts, eventually going down to 550 feet, and it was very lucrative for both the Alcatraz company and the land owner.


Hard to believe this industrial looking scene was right next to the scenic lagoon on the campus of UCSB. Alcatraz operated this mine from 1890 to 1898. When the Goleta plant was operating in its heyday, it pumped out 60 tons of asphaltum every twenty four hours. Chunks of solidified tar were loaded onto horse drawn wagons, each wagon carrying four tons, three times a day, seven days a week, down to the train station at Hollister and La Patera. Once on the Southern Pacific line, the Goleta asphalt was distributed  all around the country. Some of the historic streets of New Orleans are paved with tar from the asphalt mine in Goleta, California.


The mine employed 50 men, from local boys to experienced former gold miners, local farm workers to transients. The days were long, and the work was hard, but the pay was good. Workers made as much as $2.50 for a 10 hour shift….. 25 cents an hour!  Sounds pathetic today, but that was twice as much as a farmhand made.  The work was dangerous and unhealthy. Dynamite was often used to break through sections of congealed tar in the shaft, making the job even more hazardous. Two miners were killed in an underground explosion, and the air in the shafts was so polluted even the slightest open wound could bring on serious infections. Workers described the job as, “Hot, dirty, cramped and dangerous” and men often passed out from breathing toxic fumes.


The first shaft was dug 200 feet deep, right in the middle of an outcrop of asphaltum, and the nearby lagoon served as a convenient dumping place for the mine tailings. They soon realized their mistake in digging straight in, as the deeper they dug the more fluid the asphalt got, similar to digging into wet sand. So they dug another vertical shaft into solid earth, 100 feet away from the first, then every 50 feet down, they dug horizontal tunnels to tap into the original shaft. The tunnels were lined with 10×10 fir timbers shipped in from Oregon, but even these heavy supports often snapped like toothpicks under the pressure.


Shown here is the Carpinteria asphalt mine, also operated by Alcatraz. In 1898, Alcatraz closed the Goleta plant, and moved to a more economical surface tar pit on the Sisquoc Ranch.


Today, an opening to one of the mine shafts sits unnoticed on the busy UCSB campus. Thousands of tons of fine quality asphalt remain 200 feet below this spot, as well as a network of shafts and tunnels where brave men risked their lives trying to make a living, over a hundred years ago.

  1. Hi, just read the asphalt article and understand it better (re: my email to you a few minutes ago). I can’t quite get where More’s Landing was – since More Ranch Road leads to the Gas company and that is all cliffs – why would they use More Ranch Road and did it used to go over to the Goleta Beach or mobile home park area? Thank you for your great articles!

  2. Wonderful info. My Grandfather George R. Willey worked as a mine hoist operator for several year around 1895s. Was later called upon to locate old mine shafts when a fire fighter fell into one after UCSB (my alma mater) occupied the mesa.

  3. Hi Tom, Nice article on the asphalt industry. I really like all the articles you write and how you present them. So interesting! I had no idea there had been a mine at Campus Point, but then, isn’t it called Coal Oil Point, so no surprise, I guess. Was this the asphaltum deposit known as La Patera? I’m researching the Alcatraz Mining and Asphalt Company and trying to come up with an initial date. I can’t find them before 1895, but you mention 1890, can you give me some help on the source of that information? It’s actually for a small section for an article on William Henry Crocker in SB. Thanks for any help!
