History of Treasure Hunting in California







Golden State







GOLD







Gold was first discovered by the Spaniards as early as the 1500s, but mining operations did not begin until the 1780s along the Colorado River. Gold was next discovered in the San Gabriel River (near Los Angeles), San Francisco, Palo Alto, Santa Clara, San Jose, and Santa Cruz by Mexican prospectors who kept these finds secret. Of course, gold was then found at the infamous Sutter's Mill near Sacramento in 1848 and made headlines worldwide. The ensuing great California Gold Rush spawned massive gold discoveries in 40 counties. The richest, Tuolumne County, boasts 8 million troy ounces of gold taken since then. Lucky for you, gold has been discovered everywhere in the state!!







Placer Deposits







A placer deposit is a concentration of a natural material that has accumulated in unconsolidated sediments of a stream bed, beach, or residual deposit. Gold derived by weathering or other process from lode deposits is likely to accumulate in placer deposits because of its weight and resistance to corrosion. In addition, its characteristically sun-yellow color makes it easily and quickly recognizable even in very small quantities.







The gold pan or miner's pan is a shallow sheet-iron vessel with sloping sides and flat bottom used to wash gold-bearing gravel or other material containing heavy minerals. The process of washing material in a pan, referred to as "panning," is the simplest, most commonly used, and least expensive method for a prospector to separate gold from the silt, sand, and gravel of the stream deposits. It is a tedious, back-breaking job and only with practice does one become proficient in the operation. Thankfully, technology finally caught up with our gold fever and brought us metal detectors!







Many placer districts in California have been mined on a large scale as recently as the mid-1950's. Streams draining the rich Mother Lode region--the Feather, Mokelumne, American, Cosumnes, Calaveras, and Yuba Rivers--and the Trinity River in northern California have concentrated considerable quantities of gold in gravels. In addition, placers associated with gravels that are stream remnants from an older erosion cycle occur in the same general area.







You can always ask for permission to hunt on any private property, but there are also several places you can pan and metal detect in public access areas. As always, please respect other's claims.







Some of the following Public Access Areas are controlled by the BLM or the National Forest Service. Contact the designated authority for more information including maps and regulations before you go out.

GEMS







GARNET - Gem- and specimen-quality white to pale green grossularite garnet occurs on Indian Creek in Siskiyou County and along Traverse Creek near Georgetown in Eldorado County. Other locations for these types of grossularites are the south side of Watts Valley in Fresno County, near Selma in Tulare County, near Big Bar in Butte County and near El Toro in Orange County. Some of the finest quality spessartite garnet known come from pegmatites in San Diego County. Spessartites have been found on Gem Hill near Mesa Grande and in mines in the Rincon and Pala Districts. The most productive area with the finest quality garnets is on the western side of Hatfield Creek Valley near Romona. Near Indian Head Hill in San Diego County is a deposit of fine-quality hessonite garnet, and another deposit is near Dos Cabezas.







AGATE - California's "Mojave Blue" agate has gained a great deal of attention in the past several years. This pastel blue or blue-gray agate cuts into attractive cabochons for jewelry and, in the hands of an expert carver, makes outstanding carvings.







Specialty Stones - Deposits in the State are blessed with a variety of collector/specialty stones. Stones have been cut from fine-quality, pink apatite from San Diego County. Some small colorless stones have been cut from analcine, but the location from which the material was recovered is unknown. Fine-quality, brown colored stones have been cut from axinite from deposits in Calaveras, Madera, Riverside, and San Diego Counties. Benitoite, the State gemstone, is the collector/specialty stone for which the State is best known. San Benito County is the only source of this fine, blue colored gem. Large, fine-quality, light to medium green colored stones can be cut from fluorite found in Los Angeles County. Large, colorless stones are cut from scheelite from deposits in Kern and Inyo Counties. Nearly flawless, colorless stones have been cut from natrolite from San Benito County. The author also has seen natrolite stones that were labeled as being from Los Angeles County. Deposits in the State also yield fine-quality, brown epidote, colorless calcite and colemanite, and augelite.







QUARTZ CRYSTALS - Deposits in California are another source of significant amounts of quality quartz crystal. For many years cobbles and round crystals have been found in streambeds in Amador and Calveras Counties. The best quality, largest, and most abundant crystals come from ancient stream channels in the Mokelumne Hill area of Calveras County. Over the years, various mines in the area have produced thousands of kilograms of rock crystal, with some of the individual crystals weighing as much as 275 kilograms and many of the crystals measuring more than 600 millimeters in length and 250 millimeters in diameter. The American Museum of Natural History has a 150 millimeter sphere cut from a Mokelumne Hill rock crystal. Additionally, the pegmatites of Hiriart Hill, San Diego County, have produced hundreds of kilograms of fine-quality rock crystal from which a number of 60 to 90 millimeter spheres have been cut.







TOURMALINE - Tourmaline was, until recently, the single largest contributor to the value of gemstones produced from California. And for the past 5 years, California has ranked as high as second and as low as sixth in the value of natural gemstone produced in the United States. The State's fabulous tourmalines were discovered by the gemstone industry in the late 1870's or early 1880's. The caveat, discovery by the gemstone industry, is used because Native Americans discovered and used these beautiful tourmalines long before that.







Since their discovery, the tourmaline deposits in Riverside and San Diego Counties have had more tourmaline produced and of greater value than any other deposits in the Northern Hemisphere. In fact, it is probable that only the deposits in Brazil have been more productive.







One of the reasons for the productivity of the area is the longevity of the individual mines. Many of them have operated intermittently from the 1890's until the present. The famous Himalaya Mine is quite likely the best example.







Records indicate that from 1898 until 1914, the Himalaya was the world's largest producer of tourmaline. Furthermore, the records indicate that in 1904 production from the mine was at least 5.5 metric tons. In 1989, 84 years later, a single pocket in the mine produced more than 0.5 metric ton of tourmaline.







The history of production from the mine is not one of steady continuous operation. The mine operated continuously from 1898 until 1914, after which it operated sporadically until 1952. At this time, it once again began continuous operations that lasted until 1964 when it returned to intermittent operation until 1977. Since then the mine has been in operation under the direction of Pala International.







California tourmalines come in all colors except certain shades of blue and yellow. They also occur in bicolors, tricolors, and concentrically and laterally zoned combinations. Crystals vary in diameter from about 3 millimeters to as much as 125 millimeters, and vary in length from about 12 millimeters to as much as 250 millimeters.







Because of the large size of the crystals available, some large stones have been cut from California tourmaline. A 400-carat pink-red stone has been cut, as well as a flawless 75 carat green to pink bicolor and flawless 30- to 40 carat green to colorless to pink tricolored stones.







California deposits should continue to produce quantities of faceting, carving, and cabochon grade, as well as specimen-grade tourmalines for some time into the future. In late 1992, a new deposit of tourmaline was discovered in Riverside County that could result in greater production over even a longer period of time.







TURQUOISE - The production of turquoise from deposits in California can be traced back to pre-Colombian Native Americans. Prehistoric mining tools have been found in some of the old workings of the turquoise mines in San Bernardino County.







Over the years, the State's deposits have produced a substantial amount of turquoise. Deposits are located in San Bernardino, Imperial, and Inyo Counties. The material occurs as nodules and as vein filling. Most of the nodules are small in size, about the size of the end of your thumb, and the vein material is about 4 millimeters thick. In the better grade materials, the color varies from a pale to a dark blue, poorer grade materials are greenish-blue and green in color. Some of the material has yellow-brown limonite spiderwebbing.







In the past, a number of turquoise mines operated in the State, several or more mines in each of the counties. Today, only a single mine, the Apache Canyon Mine, is commercially producing turquoise. Material from the mine is a fine blue color, hard, and takes a good polish.

LOST TREASURE







As in other areas of the US, there are several tales of lost California treasure concerning caches buried for safety. In many of these stories, people either died or forgot where they buried the stash. Contributing factors include:







1. Federal laws making possession of gold illegal in the early 1900s







2. Distrust of banks during the Great Depression.







* In Mokelumne Hill along Route 49 in the Mother Lode country, a cache of $50 gold coins is said to be in an old foundation wall.



* A bandits' underground hiding place near Avila, San Luis Obispo County, is said to have been the depository for much loot. Can you find the cave?



* Dr. John Marsh's cache of $40,000 in gold coins, (Marsh Creek, east side of Mount Diablo, near Brentwood, Contra Costa County), would be worth many times that if it were found today.
