  • (Pyrgulopsis Robusta), Harney Lake Springsnail (Pyrgulopsis Hendersoni), and Columbia Springsnail (Pyrgulopsis New Species 6) As Threatened Or Endangered
    PETITION BEFORE THE SECRETARY OF THE INTERIOR Petition to List the Jackson Lake springsnail (Pyrgulopsis robusta), Harney Lake springsnail (Pyrgulopsis hendersoni), and Columbia springsnail (Pyrgulopsis new species 6) as Threatened or Endangered Submitted by: Dr. Peter Bowler, Biodiversity Conservation Alliance, Center for Biological Diversity, Center for Native Ecosystems, Western Watersheds Project, The Xerces Society July 2004 EXECUTIVE SUMMARY Invertebrates comprise nearly 99% of the world’s animal diversity and play an invaluable role in maintaining environmental health and integrity. Invertebrates are a part of nearly every food chain, are responsible for recycling plant and animal waste in soils and waters, and are crucial to ensuring the perpetuation of food webs. Mollusks, invertebrates characterized by their shells and which include snails, slugs, clams, mussels, and other creatures, are one of the most diverse group of animals in the world. Worldwide, it is estimated that 50,000-200,000 different mollusk species exist on land and in freshwater. These species exist in an incredible diversity of environments, playing a vital role in sustaining clean and healthy air, soil, water, and vegetation. In the western United States, which includes the states of Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington, and Wyoming, land and freshwater mollusks are probably the most diverse group of animals and comprise an irreplaceable proportion of worldwide diversity. Over a thousand species of snails, slugs, clams, and mussels are found on land and in freshwater. Scientists estimate hundreds more species have yet to be discovered. Some species in the west exist in only one or two locations, such as a desert spring, a stand of ancient forest, or a coastal island, and are found nowhere else in the world.

  • GEOLOGY - of the Cariboo River Area, British Columbia
    BRITISH COLUMBIA DEPARTMENT OF MINES AND PETROLEUM RESOURCES HON. w. K. I(IERNAN, kti?tiSte’~ P. J. MULCAHY, De~ufy Minister BULLETIN NO. 47 GEOLOGY - of the Cariboo River Area, British Columbia by A. SUTHBRLAND BROWN TABLE OF CONTENTS Geology of the Cariboo River Area, British Columbia SUMMARY The Cariboo River area includes about 1,000 square miles of dissected plateau of the Quesnel Highlands and alpine peaks of the Cariboo Mountains in east central British Columbia. The area is underlain by three groups of stratified rocks. The Kaza Group is a thick succession (lZ,OOO+ feet) of gritty feldspathic micaceous quartzitzs and silvery green schists of Late Proterozoic age. It is overlain conformably by the Cariboo Group of Cambrian, Ordovician (?), and later age. This group is composed of 7,000 to 9,000 feet of phyllites, micaceous quartzites, and limestones and is divided into six formations. Carbonate and fine elastic rocks are dominant in the lower part of the group, v;hereas coarser elastic rocks are dominant in the upper. The Slide Mountain Group is composed of at least 5,000 feet of basal con- glomerate, pillow basalts, and bedded chert, and is probably of Mississippian age. Tectonism rose to a peak toward the end of Kaza deposition, but stable shallow marine conditions persisted throughout early Cariboo deposition. Tectonism in- creased again erratically but progressively toward the close of Cariboo deposition. Folding and metamorphism preceded deposition of the Slide Mountain Group. The structure of the region culminates in a broad northwest-trending anticline, the Lanezi arch, which exposes the Kaza Group.
