INTRODUCTION Scope of Investigation With the approval of the faculty of the Geology Department of the University of Arizona, the writer chose the study of an area in the Swisshelra Mountains of south­ eastern Arizona as the subject of his thesis. This area centers in the Mountain Queen claim, the one from which has come most of the metal production from the area. The field work was carried on from January to April, 1947. A part of the Pearce quadrangle topographic sheet, U. S. Geological Survey, was enlarged by photography and pantograph to the scale of 500 feet to the inch, and used in mapping; the contours were modified where necessary during the course of mapping. Acknowledgements The writer is indebted for. advice and encouragement to every member of the staff of the Geology Department of the University of Arizona. Dr. P. W. Galbraith and Professor E. D. McKee visited the area; Dr. A.- A. Stoyanow helped in the identification of fossils, and Dr. M. N. Short in the examination of polished sections. The writer assumes full responsibility for any errors in presentation or inter­ pretation. The writer is grateful to R. L. Brown, Douglas, Joe and Elmer Ridbaun, Elfrida, and Ben Heney, Tucson, mine 2. operators in the Mountain Queen area, who gave ready per­ mission to examine and sample their workings. The plan of the Mountain Queen is based on a map loaned by R. L. Brown, operator of that property, which he received from Dr. C. A. Rasor of the-Phoenix office of the Reconstruction Finance Corporation. The history of mining has been compiled from information obtained from the above-mentioned mine operators and from Hawley and Hawley, Douglas assayers. Previous Work The Swisshelm range and isolated small peaks in the Sulphur Springs valley were mapped in 1922, on a scale of 2 miles to the inch, by C. J. Sarle, then of the University of Arizona. This map was incorporated in the State Geological Map. There was no report published. The Reconstruction Finance Corporation examined the pro­ perties in the area under the direction of Dr. C. A. Rasor in 1946. Location The area mapped in connection with this thesis comprises Sec. 12, the E. half of Sec. 11, the H. half of Sec. 13 and the N.E. quarter of Sec. 14, all in Twp. 20S., Range 27E., in southeastern Arizona. The Mountain Queen mine is located, approximately, at 31° 42* IT. Lat. and 109° 33' E. Long. It is about twenty-five miles due north of Douglas, and is 3 Reached from there by 30 miles of pavement (the Douglas- Willcox highway), thirteen miles of graveled county road (the Rucker Canyon road), and five miles of narrow gravel­ ed mine road. The closest store and post office are in the village of Elfrida, in the center of the Sulphur Springs valley, about ten miles west across the range, but twenty-four miles by the route described above, Tucson, via Tombstone and Benson, is one hundred and thirty-six miles to the northwest. Climate The climate is semi-arid, with a hot summer during which most of the rainfall occurs, a mild winter during which snow covers the ground for a week or two, a warm autumn, and a warm spring with strong westerly winds. In Douglas, twenty-five miles south and 1300 feet lower, the average annual temperature is 78.0° maximum and 46.3° minimum, with a change in temperature between day and night of 30° or higher. The monthly figures for Douglas follow in Table

Plans are published by the U.S. Fish and Wildlife Service, and are sometimes prepared with the assistance of recovery teams, contractors, state agencies, and others. Objectives will be attained and any necessary funds made available subject to budgetary and other constraints affecting the parties involved, as well as the need to address other priorities. Recovery plans do not necessarily represent the views nor the official positions or approval of any individuals or agencies involved in the plan formulation, other than the U.S. Fish and Wildlife Service. They represent the official position of the U.S. Fish and Wildlife Service only after they have been signed by the Regional Director, or Director, as approved. Approved recovery plans are subject to modification as dictated by new findings, changes in species status, and the completion of recovery tasks.

    Sky Island Grassland Assessment: Identifying and Evaluating Priority Grassland Landscapes for Conservation and Restoration in the Borderlands David Gori, Gitanjali S. Bodner, Karla Sartor, Peter Warren and Steven Bassett September 2012 Animas Valley, New Mexico Photo: TNC Preferred Citation: Gori, D., G. S. Bodner, K. Sartor, P. Warren, and S. Bassett. 2012. Sky Island Grassland Assessment: Identifying and Evaluating Priority Grassland Landscapes for Conservation and Restoration in the Borderlands. Report prepared by The Nature Conservancy in New Mexico and Arizona. 85 p. i Executive Summary Sky Island grasslands of central and southern Arizona, southern New Mexico and northern Mexico form the “grassland seas” that surround small forested mountain ranges in the borderlands. Their unique biogeographical setting and the ecological gradients associated with “Sky Island mountains” add tremendous floral and faunal diversity to these grasslands and the region as a whole. Sky Island grasslands have undergone dramatic vegetation changes over the last 130 years including encroachment by shrubs, loss of perennial grass cover and spread of non-native species. Changes in grassland composition and structure have not occurred uniformly across the region and they are dynamic and ongoing. In 2009, The National Fish and Wildlife Foundation (NFWF) launched its Sky Island Grassland Initiative, a 10-year plan to protect and restore grasslands and embedded wetland and riparian habitats in the Sky Island region. The objective of this assessment is to identify a network of priority grassland landscapes where investment by the Foundation and others will yield the greatest returns in terms of restoring grassland health and recovering target wildlife species across the region.

Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.
