STRAUSS 1Department of Earth & Planetary Science, University of California, Berkeley, California 94720, U.S.A. 2Department of Geology, Colorado College, Colorado Springs, Colorado 80903, U.S.A. 3Department of Geography and Environmental Sciences, University of Colorado, Denver, Colorado, 80217-3363 U.S.A. e-mail: [email protected] ABSTRACT: Turbidity currents generated nearshore have been suggested to be the source of some sandy marine event beds, but in most cases the evidence is circumstantial. Such flows must commonly travel through a field of oscillatory flow caused by wind-generated waves; little is known, however, about the interactions between waves and turbidity currents. We explore these interactions through detailed process-oriented sedimentological analysis of sandstone event beds from the Pennsylvanian Minturn Formation in north-central Colorado, U.S.A. The Minturn Formation exhibits a complex stratigraphic architecture of fan-delta deposits that developed in association with high topographic relief in a tectonically active setting. An , 20–35-m- thick, unconformity-bounded unit of prodelta deposits consists of dark green shale and turbidite-like sandstone beds with tool marks produced by abundant plant debris. Some of the sandstone event beds, most abundant at distal localities, contain reverse- to-normal grading and sequences of sedimentary structures that indicate deposition from waxing to waning flows. In contrast, proximal deposits, in some cases less than a kilometer away, contain abundant beds with evidence for deposition by wave- dominated combined flows, including large-scale hummocky cross-stratification (HCS). -
Historical Background Study, Curecanti Recreation Area, Colorado
•••••a••• ••••a••••aa•a COLORADO Historical Background Study By BENJAMIN LEVY DIVISION OF HISTORY Office of Areheology and Historic Preservation October 15, 1968 National Park Service B&WScans U.S. Department of the Interior ..S·fb·~~ FOREIDRD The object of th.is study is to provide the historical data necessary :fOJ: the proper development of a Master Plan for Curecanti Rec:ceation Area, Colorado. This study, authorized by Resource Study Proposal (RSP) CURE-H-1, seeks to identi:fy historical resources and historic sites lo cated within or closely associated with the recreation area. Such an undertaking will enable master planning teams to consider the use o:f historical data in interpre tive and development programs and provide £or the protection 0£ historic sites and structures. Ideally, thE! background study ought to precede the master plan team's field investigation. The urgency 0£ the Curecanti plan r1equired this investigation to be undertaken immediately at the beginning of the current :fiscal year and compelled it to be done while the team was in the field. Hopefully, this report will have found its way into the team's hands prior to their completion report. This report does not pretend to be a detailed or de £ini tive study of the history 0£ the Curecanti area. The urgency of the c:all of this document and the limited time assigned for its preparation permit little more than the examination of secondary sources, although little i published mateI'ial exists on the history ox that stretch of the Gunnison River from Montrose to Gunnison city. -

Reader's Guide to the Mountain Men of the American West
Reader©s Guide to the Mountain Men of the American West Antoine Clement, by Alfred Jacob Miller Compiled by Stuart Wier October 25, 2010 This is a guide to the best books about the mountain men of the American west which I know about. Anyone can find a book here to suit them: casual readers, students, enthusiasts, reenactors, and historians. I include a few less distinguished books, too, when they are the only thing about a topic. For some fifteen years -- roughly speaking, 1823 to 1838 and beyond -- the western U.S. was the domain of the mountain men, fur trappers who spent years traveling and living in the wilderness. Long before wagon trains, settlers, gold rushes, cavalry, Indian wars, cowboys, wild west towns, or railroads, mountain men were the first from the U.S. to see the Rocky Mountains and the lands from the plains to the Pacific. Their life was highly free and adventuresome, and often dangerous and short, lived in a shining wilderness. Where to begin? Many books, many choices. For a readable and short introduction try Give Your Heart to the Hawks by Winfred Blevins. For detailed histories try A Life Wild and Perilous by Robert M. Utley or the classic history Across the Wide Missouri by Bernard DeVoto. Or try some of the best biographies, such as Westering Man The Life of Joseph Walker by Bil Gilbert and Jedediah Smith and the Opening of the West by Dale L. Morgan. For adventures or "camp fire tales" try the personal journals and narratives written by some of the mountain men themselves. -

Sherrill1* and William H. Romme2 1National Park Service, Natural Resource Stewardship and Science, Inventory and Monitoring Program, 1201 Oakridge Drive, Fort Collins, Colorado 80525, USA 2Natural Resource Ecology Laboratory, Colorado State University, 1231 East Drive, Fort Collins, Colorado 80523-1499, USA *Corresponding author: Tel.: 001-970-267-2166; e-mail: [email protected] ABSTRACT A major environmental problem in semi-arid landscapes of western North America is the invasion of native vegetation by cheatgrass (Bromus tectorum L.), an annual Eurasian grass that covers >40 million ha of range and woodland in the western US. Cheatgrass can be especially problematic after fire—either prescribed fire or wildfire. Although cheatgrass is known to generally thrive in regions of moderate temperatures, dry sum- mers, and reliable winter precipitation, the spatial patterns of postfire cheatgrass invasion are not well characterized at finer spatial scales (e.g., within most individual landscapes). We used boosted regression trees to develop a spatial model of cheatgrass abundance 0 yr to 19 yr postfire in an 8000 km2 semiarid landscape centered on Dinosaur National Monu- ment (Colorado and Utah, USA). Elevation, a deterministic variable, was the strongest single predictor, with higher cheatgrass cover occurring below 1600 meters. Two other contingent variables, fire severity and climatic conditions in the year after the fire, -in creased the model’s predictive power. The influence of fire severity differed with the scale of analysis. -

The Routt National Forest
100 YEARS OF CONSERVATION AND PUBLIC SERVICE ON THE ROUTT NATIONAL FOREST The Early History of Forest Reserves and National Forests that formed the Routt National Forest by Mary Peterson, Forest Supervisor 2005 marks the 100th anniversary of conservation and public service for the Forest Service nationally! The Routt National Forest has also been the result of a long and colorful history in the last 100+ years! Over the next year, I’d like to share with you some of this great history of the Routt National Forest in a series of articles to celebrate our Centennial. The Routt National Forest is comprised of the dramatic and beautiful Park, Gore, Medicine Bow, Elkhead, and Flat Tops Mountain Ranges. Fortunately for us today, the beauty and resources of these mountain ranges were recognized by early conservation leaders and were set aside as forest reserves, national forests, and a national park. Over the last 100+ years, the current Routt National Forest experienced several boundary and name changes. Following is a brief reconstruction of those changes. The current Routt National Forest was produced from the entire Park Range Forest Reserve and portions of the Medicine Bow, Sierra Madre, and White River Plateau Forest Reserves, established respectively in 1905, 1902, 1906, and 1891. By an Act of Congress approved March 4, 1907, the forest reserves were renamed “national forests”, thus resulting in the creation of the Park Range, Medicine Bow, Sierra Madre, and White River National Forests. Portions of the current Routt National Forest contained portions of these four "early" national forests as well as portions of the Hayden, Colorado, and Arapaho National Forests, and Rocky Mountain National Park. -
