This five-mile gulch was the richest placer mining section in Calaveras County. It received its name from the Chileans who worked it in 1848 and 1849 , and was the scene of the so-called Chilean War. The war sparked tensions between the United States and Chilean governments and resulted in several deaths and the expulsion of Chilean miners from their claims.
The largest known quartz crystals were recovered from a mine on the south side of the gulch.
A marker was erected in 1949 by the California Centennials Commission, and the base was furnished by the Mokelumne Hill Lions Club July 4, 1949. The marker is located 1.4 miles south of Mokelumne Hill on State Highway 49.
Along with Mark Twain’s famous "The Celebrated Jumping Frog of Calaveras County" story that spun into an annual fair and Jumping Frog Jubilee, Calaveras County is rich with Gold Rush history and folklore. Remnants of the railroads and Hispanic culture add to the charm of the county located in the Sierra Nevada foothills. Calaveras Big Trees State Park, a preserve of Giant Sequoia trees, and the uncommon gold telluride mineral Calaverite was discovered in the county in 1861, and is named for it.
Calaveras is a Spanish word meaning "skull." The name was first given to the river because of the great quantities of human skulls found along the lower reaches of the river.
Calaveras County is famous for its lode and placer mines, and the largest gold nugget from the United States was taken from the Morgan Mine at Carson Hill in 1854, weighing 214 pounds. For many years it was the principal copper-producing county in California. Cement deposits from its vast limestone deposits has become one of the county's major industries in recent years.
About this Establishment
California Historical Landmarks Program
Historical Landmarks are sites, buildings, features, or events that are of statewide significance and have anthropological, cultural, military, political, architectural, economic, scientific or technical, religious, experimental, or other value. Historical Landmarks are eligible for registration if they meet at least one of the following criteria:
1) Is the first, last, only, or most significant of its type in the state or within a large geographic region
2) Is associated with an individual or group having a profound influence on the history of California
3) Is a prototype of, or an outstanding example of, a period, style, architectural movement or construction or is one of the more notable works or the best surviving work in a region of a pioneer architect, designer or master builder
California’s Landmark Program began in the late 1800s with the formation of the Landmarks Club and the California Historical Landmarks League. In 1931, the program became official when legislation charged the Department of Natural Resources—and later the California State Chamber of Commerce—with registering and marking buildings of historical interest or landmarks.
In 1948, Governor Earl Warren created the California Historical Landmarks Advisory Committee to increase the integrity and credibility of the program. Finally, this committee was changed to the California Historical Resources Commission in 1974. Information about registered landmarks numbered 770 onward is kept in the California Register of Historical Resources authoritative guide. Landmarks numbered 669 and below were registered prior to establishing specific standards, and may be added to the California Register when criteria for evaluating the properties are adopted.
