The Boulder Creek Watershed, within the Front Range region of Colorado, istypical of many western watersheds because it is composed of a high-gradient upperreach mostly fed by snowmelt, a substantial change in gradient at the range front, andan urban corridor within the lower gradient section. A stream ecosystem within anurban landscape not only can provide water for municipal, industrial, and agriculturalneeds, but also can be utilized for recreation, esthetic enjoyment, and wastewaterdisposal. The purpose of this 26 km bicycle field trip is to explore the hydrology andgeochemistry of Boulder and South Boulder Creeks and to discuss topics includingflood frequency and hazards, aqueous geochemistry of the watershed, and potentialimpacts of invasive species and emerging contaminants on stream ecology.

Roaming the Rocky Mountains and Environs: Geological Field Trips
Prepared following the 2007 GSA Annual Meeting in Denver, Colorado, these 15 guides illustrate the latest geological and archeological thinking on a variety of current research themes. Regional-scale topics include landscape responses to dynamic processes of volcanism and uplift in Yellowstone and western Colorado, geomorphic evolution along the Front Range of Colorado and on the High Plains of South Dakota, and geoarchaeological research in central Colorado and western Nebraska. A series of papers illustrates tectonic and stratigraphic processes through time and space, with discussions of Precambrian structures in western Colorado, Jurassic deposition in south-central Colorado, and near-shore stratigraphic patterns in the Cretaceous strata of the Book Cliffs. One paper reviews potential seismic signatures in Cretaceous and Early Tertiary strata in northern Wyoming and Montana, and another discusses patterns of extension in southern Nevada and adjacent portions of California. Other topics in this well-rounded volume include the history of volcanism and gold mineralization at Cripple Creek, development of coalbed methane resources in the Powder River Basin, and a long-lived subsurface coal fire in western Colorado. Follow in the footsteps of these field trips, and see for yourself the patterns and evidence discussed.
