Hydraulic mining and the California Gold Rush
Вставка

- When it comes to gold mining during the California Gold Rush, what many people visualize is a gold miner hunched over at a river panning for gold with a tin pan. For placer mining during the Gold Rush, using a gold pan didn’t last long and more environmentally destructive practices were used.
In this video, Kathy discusses hydraulic mining. Hydraulic mining involved using large high-pressure water cannons to wash away hill sides looking for gold veins in quartz. Although it was successful in extracting gold, the widespread use of hydraulic mining resulted in extensive environmental damage, which resulted in increased flooding and erosion. These problems led to the Sawyer decision in 1884, one of the first environmental laws passed in the United States, the regulation of hydraulic mining in California. Malakoff Diggins State Historic Park outside of Nevada City, CA is a great, and unfortunate, example of the lasting impacts of hydraulic mining.
Learning about the California Gold Rush, mining methods, and their environmental impacts is part of our Gold Rush school program. Interested in learning more about our school programs? Check out: sachistorymuseu...

I love your presentations!
Yes, that was good
i love these videos! she is a great presenter
Bummer, I was really hoping the rocks was for catapulting
New face today I liked this video a lot I watch daily this video was different Thanks
Thank you for watching but we’ve posted many videos with Kathy!
@@SacramentoHistoryMuseum I get notifications on the shorts each day I don’t know if it’s a setting or what I just get the shorts notification
Ivreally do enjoy theese
Great presentation, Kathy! I love the way you tell stories - life really is in the details and between your intelligence and your personality, you most definitely possess the knack for teaching us!
That judge was awesome way before being awesome was even a thing 😊 I wonder if he knew of President Teddy Roosevelt? For some reason, my heart says the judge not only knew of Roosevelt, but the judge actually knew the President, himself. Just because history is cool like that!
The giggle at the end is charming - it tells me y’all have a lot of fun working at the museum. Thank you for that, Kathy!
Jared will never live that down, Howard truly loves it, as do your fans!!! 😂😂🔴
“so the people who like mountains, and the people who hate floods got together” is underrated
i am laughing
Happy to know environmentalists exists even back then.
President Teddy Roosevelt (1901 - 1909, R) was a huge conservationalist. You can read more about him here: www.whitehouse.gov/about-the-white-house/presidents/theodore-roosevelt/
Environmentalism had nothing to do with it. Hydraulic mining was literally destroying much of the State of California. Completely. Read “Gold vs. Grain” for detailed story. The extreme damage hydraulic mining did in the Sierra Nevadas (and foothills) can be seen everywhere. Driving I80 at Gold Run Dutch Flat the freeway goes right through a huge hydraulic mine.
Thank you!
I remember learning about this from Huell Howser on California's Gold. I have to visit this museum.
Haha same here. Rest in peace Huell.
Very cool
Thank you both very much. Just a little different version of "Strip Mining" I assume. And with all due respect, Rock that Red Button Jared.
A really terrific historical interpretation presentation… kudos to this docent (guide).
However, a major error at the end; an amazing error… the box of rocks on the hydraulic monitor have nothing to do with aiming. The rocks are there as a counterweight for the monitor. Aiming or manipulating the monitor was done in a much more sophisticated manner.
The monitor could be aimed right/left and up/down because it swiveled on a universal two-axis ball joint.
At the nozzle end of the monitor there was a deflector device that could change the direction of the water stream. If the stream was deflected to the right the monitor would swing to the left. If the deflection was up, the monitor would swing down. And so forth. Think of how today’s jet boats are steered. The deflector was controlled by an operator standing beside the monitor.
It was an elegant and genius mechanism and worked perfectly. You can see this in action in various UA-cam videos.
Thx. The Malakov diggings look like a waist land.
Brutal ending... poor Gary! 😳😬🙄💁
Press the red button Jared lol
Good video
Wow that water beam on the photo doesn't look that powerful. I thought as the lady described, the water pressure is build by gravity. How did they get the actual pressure to reach this speeds?
The water was brought down from the High Sierras in thousands of miles of canals. The monitor in the video is tiny; some had nozzles over eight inches across. The pressure was enormous. If you chopped the stream with an ax you’d end up with broken wrists.
When hydraulic mining was made illegal an amazing technology miracle occurred… about the same time the Pelton Water Wheel was invented (extremely efficient under high pressure) AND long distance electrical power transmission was invented (Tesla’s AC). The high pressure water previously used for hydraulic mining was subsequently used in hydroelectric power houses; many are still in use today.
