Abstract A new species of homolid crab, Zygastrocarcinus tricki sp. nov., is reported from the Late Cretaceous (middle Campanian, Baculites scotti Zone) of the Pierre Shale Formation (Baculite Mesa, Pueblo County, Colorado). This nearly complete homolid, hereto described is the sixth species assigne

Lava flows southwest of Glenwood Springs, Colorado, have been broken by numerous faults with a few tens to several hundreds of feet of perpendicular separation. Flexural slip in steeply upturned Upper Cretaceous and Tertiary strata beneath the lava flows is believed to be responsible for this faulti

GC skew is a measure of the strand asymmetry in the distribution of guanines and cytosines.GC skew favors R-loops, a type of three stranded nucleic acid structures that form upon annealing of an RNA strand to one strand of DNA, creating a persistent RNA:DNA hybrid.Previous studies show that GC skew

Due to the lack of a dense network of reporting stations in the Grand Junction, Colorado area and the inadequate representation of shower activity by observations of rain at a single rain gage, certain arbitrary criteria were set up to define a “shower” day at Grand Junction. Relationships of a numb

Abstract. A declining spring snowpack is expected to have widespread effects on montane and subalpine forests in western North America and across the globe. The way that tree water demands respond to this change will have important impacts on forest health and downstream water subsidies. Here, we pr

Abstract. Harry Gunnison Brown's fifty plus years of active advocacy of land value taxation are reviewed in the light of two recent articles. One indicates a waning interest and even understanding of Brown's chosen cause while the other demonstrates quite the opposite: the persistence and relevance

The delta of the Colorado River in Mexico historically contained 780,000 ha of riparian, marsh, and gallery forest habitat. Similar to other desert river deltas, such as the Nile and Indus, the lower delta of the Colorado River has been severely affected by the upstream diversion of water for human

Understanding the abiotic drivers of high-elevation forest physiognomy is essential for forecasting how mountain ecosystems will respond to emerging environmental pressures. Most prior studies of these relationships have relied on small samples of the full landscape, resulting in limited power to de

Recent research in Pennsylvanian-Permian strata of the Fountain Formation adjacent to the Front Range uplift and the Cutler Formation adjacent to the Uncompahgre uplift (Colorado) has resulted in new hypotheses about the climate and tectonics of the Ancestral Rocky Mountains. The Fountain and the Cu

At Camp Albion, Boulder County, Colorado, an unusual assemblage of ore and gangue minerals is found in a sheared and brecciated zone cutting the contact between pre-Cambrian gneiss and a composite Tertiary monzonite stock.Petrographic and chemical-mineralogic studies suggest that the ore was deposit
