Almaden Quicksilver County Park facts for kids
Almaden Quicksilver County Park is a large park in south San Jose, California, USA. It covers about 4,163 acres (17 square kilometers). This park used to be a place where people mined for a special metal called mercury. Mercury is also known as "quicksilver."
The park has many different elevations, from low areas near 600 feet (183 meters) above sea level to high points over 1,700 feet (518 meters). The County of Santa Clara owns and manages this park. Inside the park, you can find the Guadalupe Reservoir and enjoy amazing views of San Jose. The Almaden Reservoir is also right next to the park.
Near the park, in a town called New Almaden, there is the Casa Grande Almaden Quicksilver Mining Museum. The park gets its name from the New Almaden Quicksilver Mines. These mines were named after an old mercury mine in Almadén, Spain. The mercury from these mines was very important during the California Gold Rush. It was used to help get gold out of ore.

Discovering the Park's Mining Past
The New Almaden Mines in this park were open for a very long time, from 1847 to 1976. These mines were super important during the California Gold Rush. Mercury was needed to pull gold out of the rocks. Imagine how much gold was found!
By the time Santa Clara County bought the mines in 1976, a huge amount of mercury had been taken out. Over 83 million pounds (37,388 metric tons) of mercury were extracted. That was worth more than $70 million!
What Remains from the Mining Days?
Today, you can still see parts of the old mining operations scattered around the park. These are the remains of buildings from 135 years of mining. At one time, up to 1,800 miners lived and worked here.
The biggest collection of these old structures is at a place called English Camp. This camp was set up by miners from Cornwall in the 1860s. You might also find some buildings that were built later by the U.S. Army Corps of Engineers. There's even a special memorial honoring Civilian Conservation Corps firefighters who were stationed there.
From Mines to a Beautiful Park
After the mines closed, the county worked hard to turn this area into a park. Between 1976 and 1978, Santa Clara County created several new large parks very quickly. Almaden Quicksilver County Park was one of them.
Soon after buying the mining land in 1976, the county started planning how to use it as a park. The county parks program was growing fast at that time.
Creating a Park for Everyone
The director of the county parks had a great idea. They wanted to create a historic park where visitors could learn about the mining past. They also wanted people to enjoy the amazing nature and different kinds of plants and animals, known as biodiversity.
Plans were made for the park's facilities. They also prepared an Environmental Impact Report. This report looked at how the park might affect the environment.
The main things they looked at when planning the park were:
- How park visitors might affect the homes of animals and plants.
- Making sure the water in the creeks stayed clean.
- How new roads might look and affect water flow.
- Studying the history of how the mines were used.
