Copper King Mine, Silver Crown District, Wyoming (Preliminary Report)
2012 Copper King Mine, Silver Crown District, Wyoming (Preliminary Report) W. Dan Hausel Independent Geologist, Gilbert, Arizona 11/14/2012 COPPER KING MINE, SILVER CROWN DISTRICT W. Dan Hausel, Independent Geologist Gilbert, Arizona Introduction The Silver Crown district (also known as Hecla) lies 20 miles west of Cheyenne and immediately east of Curt Gowdy State Park along the eastern flank of the Laramie Range. The district is visible on Google Earth (search for ‘Hecla, Cheyenne, WY’) and lies within the boundaries of the Laramie 1:100,000 sheet. This area was initially investigated by Klein (1974) as a thesis project, and also by the Wyoming Geological Survey as a potential target for low-grade, large-tonnage, bulk minable gold and copper (Hausel and Jones, 1982). Nearly all mining and exploration activity in the district centered on the Copper King mine and the Hecla ghost-town with its mill constructed to support mining operations in the area (Figure 1). However, the mill was so poorly designed that rejected tailings often assayed higher than the mill concentrates (Figure 2) (Ferguson, 1965). This has been a common problem with many mines in the West – poorly designed mills. For example, four mills constructed nearby in the Colorado-Wyoming State Line district to extract diamonds, rather than copper and gold from 1979 to 1995, also had recovery problems. The last mill built at the Kelsey Lake mine (40o59’38”N; 105o30’05”W) was not only constructed on a portion of the ore body, but also lost many diamonds. After several months of processing, tailings were checked and the first test sample yielded several diamonds including a 6.2 carat stone. -
Published Proceedings from the CWD Forum
PROCEEDINGS Jackson Hole Chronic Wasting Disease Forum December 7, 2016 National Museum of Wildlife Art Jackson, Wyoming INTRODUCTION The purpose of this Chronic Wasting Disease forum was to highlight CWD research and management considerations, with the goal to share current science-based information with the general public and all organizations concerned with the long-term health of elk and deer populations in the Jackson Hole Area. ABSTRACTS *Names of presenters in bold text Wyoming Chronic Wasting Disease Surveillance Mary Wood, State Veterinarian, Wildlife Veterinary Research Services, Wyoming Game and Fish Department, Laramie, Wyoming, USA Chronic Wasting Disease (CWD) was first described in captive mule deer from Colorado and Wyoming in the 1970’s (Williams 1980). After the initial discovery and description of this disease, the Wyoming Game and Fish Department (WGFD) began collaborative work with Dr. Elizabeth Williams in 1982 to investigate whether the disease was present in free-ranging populations (Williams 1992, Miller 2000). This was the beginning of a decades-long surveillance program to study the distribution and spread of this disease in free-ranging cervid populations. Between 1982 and 1997 a limited number of CWD samples were collected through local check stations near Laramie and Wheatland WY. WGFD surveillance began in earnest in 1997, with peak surveillance occurring between 2003 and 2011 when federal funding was available. Currently the WGFD Wildlife Health Laboratory tests between 1500 and 3500 samples for CWD each year with over 56,000 samples tested to date in Wyoming. Surveillance includes voluntary sample collection from hunter harvested animals as well as collection from road-killed animals and targeted animals showing signs consistent with CWD. -

Oreohelix land snails of Heart Mountain Ranch and Tensleep Preserve, Wyoming. Prepared by the Wyoming Natural Diversity Database, University of Wyoming for The Nature Conservancy. Mountain snails (Oreohelix sp.) are generally considered rare. In fact, Oreohelix peripherica wasatchensis is a candidate species in Utah under the Endangered Species Act, and several species of Oreohelix are considered critically imperiled by NatureServe. In Wyoming, Oreohelix pygmaea is an endemic species (only found in Wyoming) that lives in the Bighorn Mountains. Another species being watched in Wyoming and South Dakota is Oreohelix strigosa cooperi (referred to as Oreohelix cooperi by some), which is only found in the Black Hills and was petitioned for listing under the Endangered Species Act in 2006, but not listed. Oreohelix are relatively large land snails, but little is known about this genus. As their common names suggests, mountain snails live in mountainous regions of western North America. These land snails are active during wet, cool mouths of the year (i.e., early summer). Oreohelix carry their young internally until they are born at ~2.5 whorls. Mountain snails are one of the more obvious land snail genera, because of their large shell size (10-20 mm diameter). -

A Preliminary Assessment of Paleontological Resources at Bighorn Canyon National Recreation Area, Montana and Wyoming
A PRELIMINARY ASSESSMENT OF PALEONTOLOGICAL RESOURCES AT BIGHORN CANYON NATIONAL RECREATION AREA, MONTANA AND WYOMING Vincent L. Santucci1, David Hays2, James Staebler2 And Michael Milstein3 1National Park Service, P.O. Box 592, Kemmerer, WY 83101 2Bighorn Canyon National Recreation Area, P.O. Box 7458, Fort Smith, MT 59035 3P.O. Box 821, Cody, WY 82414 ____________________ ABSTRACT - Paleontological resources occur throughout the Paleozoic and Mesozoic formations exposed in Bighorn Canyon National Recreation Area. Isolated research on specific geologic units within Bighorn Canyon has yielded data on a wide diversity of fossil forms. A comprehensive paleonotological survey has not been previously undertaken at Bighorn Canyon. Preliminary paleontologic resource data is presented in this report as an effort to establish baseline data. ____________________ INTRODUCTION ighorn Canyon National Recreation Area (BICA) consists of approximately 120,000 acres within the Bighorn Mountains of north-central Wyoming and south-central Montana B (Figure 1). The northwestern trending Bighorn Mountains consist of over 9,000 feet of sedimentary rock. The predominantly marine and near shore sedimentary units range from the Cambrian through the Lower Cretaceous. Many of these formations are extremely fossiliferous. The Bighorn Mountains were uplifted during the Laramide Orogeny beginning approximately 70 million years ago. Large volumes of sediments, rich in early Tertiary paleontological resources, were deposited in the adjoining basins. This report provides a preliminary assessment of paleontological resources identified at Bighorn Canyon National Recreation Area. STRATIGRAPHY The stratigraphic record at Bighorn Canyon National Recreation Area extends from the Cambrian through the Cretaceous (Figure 2). The only time period during this interval that is not represented is the Silurian. -
Fracture Analysis of Circum-Bighorn Basin Anticlines
FRACTURE ANALYSIS OF CIRCUM-BIGHORN BASIN ANTICLINES, WYOMING-MONTANA by Julian Stahl A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Earth Science MONTANA STATE UNIVERSITY Bozeman, Montana November 2015 ©COPYRIGHT by Julian Stahl 2015 All Rights Reserved ii DEDICATION I dedicate this thesis to my brother, Manuel Stahl, who provided me with the inspiration and drive to pursue a degree that I am truly passionate about. iii ACKNOWLEDGEMENTS The research presented in this document would not have been as thought- provoking and thorough without the help of my mentors and peers. My advisor, Dr. David Lageson helped formulate the project idea and was fundamental throughout the course of my study in leading me in the right direction and always being available to answer questions. I would also like to extend my gratitude to my committee members, Dr. Colin Shaw and Dr. Jean Dixon, for providing me with the necessary assistance and expertise. I would also like to thank my fellow geology peers at Montana State University. Without the constant communication and discussions with Mr. Jacob Thacker, Mr. Travis Corthouts and Mrs. Anita Moore-Nall this project would not have come to fruition. I would also like to offer my sincere appreciation to my two field assistants, Mr. Evan Monroe and Miss Amy Yoder, for taking the time out of their lives to help unravel the geology of the Bighorn Basin in the field. I would like to express my gratitude to my entire family, Dr. Johannes Stahl, Ms. Gabriele Stahl and Mr. -
