Book Description
First published in 1901, “Our National Parks” is a fantastic guide to the wild mountain forest reservations and national parks of the United States, exploring their beauty and usefulness in an attempt to encourage contemporary readers to go out and enjoy the natural wonders of North America. John Muir (1838–1914) was an influential Scottish-American naturalist, environmental philosopher, botanist, zoologist, author, and glaciologist who famously fought to preserve wilderness in the United States of America. Muir's work describing his adventures in nature have been read by millions the world over and his activism has helped to conserve such important places of natural beauty as the Yosemite Valley and Sequoia National Park in America. Contents include: “The Wild Parks and Forest Reservations of the West”, “The Yellowstone National Park”, “The Yosemite National Park”, “The Forests of the Yosemite Park”, “The Wild Gardens of the Yosemite Park”, “Among the Animals of the Yosemite”, “Among the Birds of the Yosemite”, “The Fountains and Streams of the Yosemite National Park”, etc. Other notable works by this author include: “My First Summer in the Sierra” (1911), “Steep Trails” (1918), and “The Story of My Boyhood and Youth” (1913). A Thousand Fields is republishing this classic book now complete with a biographical sketch of the author.

Book Description
This is a summary of the known facts about the minerals that make up the rocks, soils, and ore deposits of Colorado. Compilation and abridgment of the literature from 1858, when gold was discovered, through 1957 (with a few additions for 1958 and 1959) is supplemented by information from unpublished sources. Designed to be of use to both professional and amateur mineralogists, the main part of the report describes the chief occurrences of 445 mineral species,42 of them first found in Colorado, together with many subspecies, varieties, and discredited "type" species. Directions for finding these localities are also given in the text. The bibliography contains more than 800 selected references to the most significant literature on the subject

Book Description
With its thickness of more than 15 km of strata, covering some 200,000 km2, the Belt basin displays one of the planet's largest, best-exposed, most accessible, and best-preserved sequences of Mesoproterozoic sedimentary and igneous rocks. This volume focuses on research into this world-class province; kindles ideas about this critical era of Earth evolution; and covers aspects of the basin from its paleontology, mineralogy, sedimentology, and stratigraphy to its magmatism, ore deposits, geophysics, and structural geology.

Book Description
Skarns in British Columbia have historically been important sources of iron, tungsten, copper, and gold. This publication begins with an introduction on skarn terminology and the problems of skarn identification. It then reviews a genetic model of skarn formation and presents descriptive profiles of eight types of skarn deposits; describes the database of at least 735 skarn occurrences in the province, and the number and distribution of skarns in British Columbia according to their associations, class, age, and distribution; and notes the ages of British Columbia skarns and the total production of various metals extracted from British Columbia skarns. Subsequent sections provide information on assays and metal ratios of mineralized skarns, skarn mineralogy, skarn mineral chemistry, chemistry of skarn-related intrusions, and the mapping and evaluation of skarns. The appendix contains a listing of 735 skarn occurrences in British Columbia, giving deposit name, MINFILE number, latitude/longitude, elements and minerals present, and associated rocks and their ages.
