The narrative of historic activities serves as a guide and yardstick regarding what physical evidence of these activities—historic sites, structures, ruins and objects—are known or suspected to be present on the land, and evaluation of what their historical significance may be. Such information is essential in making a wide variety of land management decisions effecting historic cultural resources. Objectives: As a basic cultural resource inventory and evaluation tool, the narrative and initial inventory of known historic resources will serve a variety of objectives: 1. Provide information for basic Bureau planning docu¬ ments and land management decisions relating to cultural resources. -

Pennsylvanian Minturn Formation, Colorado, U.S.A
Journal of Sedimentary Research, 2008, v. 78, 0–0 Research Articles DOI: 10.2110/jsr.2008.052 DEPOSITS FROM WAVE-INFLUENCED TURBIDITY CURRENTS: PENNSYLVANIAN MINTURN FORMATION, COLORADO, U.S.A. 1 2 2 3 2 M. P. LAMB, P. M. MYROW, C. LUKENS, K. HOUCK, AND J. 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). -

Masterson A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Geology Thesis Committee: Robert B. Perkins, Chair Carl Palmer John Bershaw Maxwell Rudolph Portland State University 2016 ABSTRACT The Piceance Creek Basin in northwestern Colorado contains extensive oil shale deposits that produce natural gas and which could potentially yield ~1.5 trillion barrels of shale oil. However, much of the oil shale lies at depths too great for traditional mining practices and various innovative approaches for in situ conversion of kerogen to oil have been proposed. A firm understanding of the existing hydrogeochemistry is needed as resulting mineralogical changes or rock-fluid reactions may affect rock porosity and permeability. -

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. -
