Enjoy the map of 1910 issued by the State Mining Bureau featuring the many mineral deposits of Southern California. This map is divided into four easy to read sections.
The details of Inyo County are outstanding as shown on the map of 1883. The interesting text accompanying this map has been included.
The gemstone site locations have been compiled from many sources and detailed on a modern USGS planometric map. Many sites are may be found east of Owens Lake. The desert area of Southeastern California should be a rockhounds delight.
Map identifies locations of: gold and silver, actinolite, agate, amethyst, andesite, apatite, autunite, aragonite, azurite, anglesite, barite, beryl, bornite, bloodstone, calcite, chalcopyrite, chalcedony, chert, chrysocolla, dumortierite, epidote, feldspar, flourite, fossils, garnet, geodes, hematite, ilmenite, kyanite, jade, jadeite, jasper, limonite, magnetite, malachite, obsidian, olivine, onyx, opal, opalite, petrified palm, petrified wood, psilomelane, quartz, realgar, rhodochrosite, rhodonite, rhyolite, siderite, scheelite, schist, serpentine, stibnite, sphalerite, sphalerite, wollastone, wulfenite, travertine, tourmaline, and turquoise.
The famous Estwing Geo/Paleo Pick GP100 has made a grand reentry after being out of production for several years. The handle has been beefed up to make the unit even stronger. It is 25 inches long with a total weight of 3 pounds. Painted steel with a soft vinyl grip. The light weight but great strength of this makes it a great field tool for any geologist or rockhound.
Not only is this a great digging tool but I use mine to help me navigate the steep slopes of mine tailings. Jab the tip in and pull yourself up then use the hoe end to cut a quick shelf to work from.
California Gold & Gems Maps, Northern Edition is a comprehensive collection to assist the rockhound in locating 40 gem sites. The source of information has been taken from numerous publications. All known types of rock and gem deposits could not be included because of the numerous types and locations would be overwhelming. Some of the reported gold and gold districts are included as far back as 1850.
The first report of gold in California was published in Spain in 1510. California was believed to be an island north of Mexico where gold and precious stones were abundant. Gold was actually mined in California as early as the late 18th century but the "rush" did not begin until the discovery at Sutters Mill in 1848.
Rock and Gem collecting in California is virtually unlimited as illustrated by the key symbols on each USGS map section. A few counties that host exciting deposits are as follows: Siskiyou, Trinity, Tehama and Plumas.
The early maps included in this publication were located in various archival collections. The primary sources were the National Archives and the California State Library. The U.S. Geological Survey supplied the featured modern map. The design is planietric for clarity.
Map identifies locations of: gold and silver, actinolite, agate, amazonite, amethyst, apatite, apache tears, argonite, azurite, beryl, calcite, carnelian, chalcedony, chert, chrysocolla, epidote, feldspar, flourite, fossils, garnet, geodes, hematite, jade, jasper, kyanite, malachite, obsidian, opal, orthoclase, petrified wood, psilomelane, pyrite, quartz, rhondonite, rhyolite, serpentine, topaz, travertine, tourmaline, turquoise, and wollastonite.
The Deluxe Moh's Hardness Pick Set now comes in two case types. The wooden case is small enough to carry and the top screws into the base to make a perfect desk stand. The plastic case is longer but the thinner size makes it easier to carry in your field tool set.Hardness is an important and quantifiable physical characteristic of a mineral and in your effort to identify an unknown mineral, the hardness, if known, combined with other properties, can narrow your search to just a handful of possibilities. Simply scratch a smooth surface of your unknown mineral with the picks of various indicated hardness. As an example, if a No. 5 pick scratches the mineral, but a No. 4 pick does not, then your mineral hardness is 4.5. Then compare this against a table of minerals listing hardness values to aid in identifying the unknown mineral.
Chisel edge rock hammers are typically used when you want to split layers of rock apart when looking for fossils.

Description: Eastern California boasts the greatest dryland relief in the contiguous United States, between 14,499-foot Mt. Whitney in the Sierra Nevada and minus-282-foot Badwater Basin in Death Valley. That relief offers a rich variety of environments--and spectacular geology. Through driving and walking tours, Geology Underfoot in Death Valley and Owens Valley provides an on-the-ground look at the processes sculpting the terrain in this land of extremes.
Illustrated with photographs, maps, and diagrams, each geological vignette weaves the tale of a particular scene, feature, or relationship in the landscape. Some sketches ponder questions that have puzzled geologists: what formed the turtlebacks in the Black Mountains and how do stones mysteriously slide on desolate Racetrack Playa? Others spotlight the role of volcanoes and earthquakes as landscape artists: the superb lava columns of Devil's Postpile, the massive steam explosion at Ubehebe Crater, and fault scarps that shape a golf course's greens. Still others focus on less obvious but equally powerful geologic processes: boulders shattered by salt crystals and rocks blasted by windblown sand. Together, these snapshots introduce readers to eastern California's rich, dynamic geology.
