Gunnison Sage-Grouse (Centrocercus minimus) is a species of concern for which little demographic information exists. To help fill this information gap, we investigated factors affecting nest success in two populations of Gunnison Sage-Grouse. We assessed the relative effects of (1) vegetation charac

One of the major contributing factors affecting wilderness resources is camping.The objectives of this study were to describe the resource changes that occur in backcountry campsites in Rocky Mountain National Park as measured by campsite area and campsite score from the Backcountry Campsite Impact

Private lands harbor a large proportion of the world’s biodiversity, and they are also facing widespread threats from extractive land uses, anthropogenic disturbances, and land conversion for residential and commercial development. With decreased funding and support for public land acquisition and m

The Permian to Jurassic stratigraphy of the Colorado Plateau includes a number of units that were deposited under arid depositional conditions. These units each show distinctive weathering characteristics which cannot solely be attributed to variation in depositional environment or burial history. T

In recent years, large petroleum discoveries within the lacustrine microbialite facies of pre-salt systems of offshore Brazil, Angola, and Gabon have increased interest in the potential of microbial carbonates as reservoir rocks. Whereas a multitude of studies have been conducted on microbialites an

Chants have no words. They are spiritually uplifting in a motion.-Clifford DuncanThe rock art of the Uncompahgre Plateau in western Colorado includes the Uncompahgre and Gunnison River drainage system on the eastern side, and the Dolores River drainage on the western side. According to Clifford, thi

The late Paleozoic Cutler Formation, where exposed near the modern-day town of Gateway, Colorado, has traditionally been interpreted as the product of alluvial fan deposition within the easternmost portion of the Paradox Basin. The Paradox Basin formed between the western margin of the Uncompahgre U

Clifford Duncan, a Northern Ute elder, believed in educating the public to know and understand the meaning of Ute petroglyphs. By doing this, he believed it would help to preserve and protect them. Over the course of eight years, Clifford and the author visited and revisited all of these sites, disc

Seismic, well, field and gravity data are used to further understand the Uncompahgre fault near Nucla, Colorado, Paradox Basin, USA. The data help explain the complex sedimen- tary and structural history associated with faulting and salt flowage along the eastern margin of the Paradox Basin. Near Nu

Dryland winter wheat (Triticum aestivum) cropping systems dominate most of the agricultural landscape in Colorado’s semi-arid eastern plains. Since this area’s climate is characterized by frequent heat and drought, it is important to maximize water use efficiency to make agricultural lands as produc
