Gold and gems have fascinated men since time immemorial, and few men have hunted, mined and cut them over such a long and adventurous period of time as has Fred J. Rynerson. For over fifty-two years he was on their trail, particularly as one of the chief characters in that fabulous and romantic period of California history when the great gem mines of San Diego County gave up their secrets. Gold also lured him on exciting trips among the desert washes and hills along the Colorado River and north into the savage wilderness and rain forests of the Olympic Peninsula in Washington.
Here is told in intimate and often humorous detail how treasures were found and lost, how rattlesnakes, desert thirst and road-destroying floods were met and conquered, and many another thrilling and sometimes violent encounter with nature or with man. It is a tale attractively told of an era of western pioneering and adventure long past, but preserved in this book for out enjoyment and knowledge. The amateur prospector will find useful hints on how to locate valuable minerals and gems, the gemologist will deepen his understanding of the development of gem mining and of cutting and polishing techniques, while the lost treasure hunter will be able to add a few more prospective places to hunt for his dream of lost riches. Fred J. Rynerson, one of the last of the great western prospectors and miners, passed away in 1960, but the sharp mind that saw both into human character and hidden secrets of the earth, his wry wit and his bluff and keen enjoyment of the out-of-doors and hunt for earth treasures, marches on with the words he has written for us here.
Field Geology Illustrated, 2n Edition was designed to serve as a field reference to aid in recognizing, interpreting, and describing geologic features at the outcrop. Emphasis is on the study of mesocopic features that can be viewed at outcrop scale rather than large structures or landscapes. This book is not an exhaustive or comprehensive treatise on the subject of field geology, but instead cover the information necessary to understand and describe most outcrops...
Field Geology Illustrated should be useful as a complementary text for any field-related geoscience course such as physical geology, field geology, petrology, and structural geology. The detailed descriptions, illustrations and photographs of geologic features in their field setting will be particularly useful (AG: on a field trip, vacation, or) where field trips are not feasible.
This book is also intended for anyone who needs a good basic review of field geology including graduate students preparing for field mapping, professional geologists who wish to bring their skill up to date quickly and easily and even serious amateur geologists (AG: We believe this is useful to anyone interested in geology in the field!)Self study will be particularly rewarding because an interpretative sketch and detailed description is included with each photograph.
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.
