Geography

Almaden Quicksilver County Park is located in Santa Clara County to the south of the city of San Jose and the San Francisco Bay Area. Although it is located near some of the most densely populated cities in California, Almaden Quicksilver is surrounded by a number of other parks and public lands.

To the west of Almaden Quicksilver is Calero County Park and Rancho Canada del Oro Open Space Preserve. The park is bordered to the south and the west by the Sierra Azul Open Space Preserve. Additionally, it is located just north of The Forest of Nisene Marks State Park, to the west of Big Basin Redwoods State Park, and east of Henry W. Coe State Park.

Geology

The two hills in Almaden Quicksilver County Park are part of the foothills of the Santa Cruz Mountains, which stretch from the Bay Area down the Central Coast to the Salinas Valley, which separates them from the coastline of Big Sur, the Ventana Wilderness, and Los Padres National Forest. Moreover, the Santa Cruz Mountains are a subrange of the California Ranges, which covers most of the southwestern and southern parts of California.

Almaden Quicksilver County Park

Geologically, the Santa Cruz Mountains and Almaden Quicksilver County Park were formed through the uplift of a section of the San Andreas Fault. Much of the bedrock in the area is part of the Salinan Block, a granitic block that is found between the Big Pine Fault and the Nacimiento fault.

What makes the area around Almaden Quicksilver County Park unique, however, is the region’s high concentration of mercury deposits. Mercury, a.k.a. “Quicksilver” was mined extensively in the park during the California Gold Rush as mercury is essential for processing gold ore.

Flora and Fauna

Despite its 135 year history as an active mercury mine, Almaden Quicksilver County Park is a highly biodiverse area teeming with wildlife. The park is home to an assortment of mammals, including beavers, gophers, mule deer, wild boar, bobcats, mountain lions, coyotes, skunks, foxes, and shrews. It’s also known habitat for a surprising array of amphibians, including the American bullfrog, California giant salamander, and the California Newt.

Almaden Quicksilver County Park has a chaparral and oak woodlands ecosystem. During the spring and summer, it is also a good place to visit if you want to see beautiful wildflowers in bloom.

Human History

The region in and around the Almaden Quicksilver County Park is the ancestral home of the Ohlone people, among others. They frequently used the region’s cinnabar - bright red mercury ore - deposits for paint.

During the 1840s, an English textile firm based in Mexico gained the rights to mine the region, naming it Nueva Almaden (New Almaden) after the mercury mine in Almadén, Spain, which dates back centuries. As soon as the mine opened, there were disputes over who had the rights to mine on the land, a conflict that eventually made its way up to the Supreme Court.

Over the course of its 135 years of operation, the New Almaden mine became both the oldest and most productive mercury mine in the United States. By the time the mine closed, it had produced over 41,980 tons (38,090 metric tons) of mercury, which was worth more than $70 million.

The mine’s activity caused the mercury pollution of the Guadalupe River and the southern part of the San Francisco bay, which led to numerous lawsuits and then a settlement of over $6 million for habitat restoration projects.

New Almaden eventually closed in the 1970s after it was purchased by Santa Clara County and all entrances to the mine are now boarded up. The region was designated as a Superfund site and, which helped to aid the containment and clean-up process to restore wildlife habitat in the area.

It was officially designated as a National Historic Site in 1961. After Santa Clara County purchased the land in the 1970s, it was converted into a park for outdoor recreation. The nearby New Almaden Quicksilver Mining Museum also provides visitors with historical information about the park.
