The Boulder Creek Watershed, like many western watersheds, is composed of a high-gradient upper reach mostly fed by snowmelt, a substantial change in gradient at the range front, and an urban corridor within the lower section. Water from Boulder Creek provides many services, including drinking water, crop irrigation, power plant cooling, wastewater disposal, recreation, and aquatic life habitat. A multi-use path follows Boulder Creek through the city of Boulder, serving as a link to parks, schools, a hospital, a library, public transportation, and businesses, and provides the opportunity to observe many of the important uses and features of the Boulder Creek corridor. This 16-mile field trip will follow this path, using rented bicycles, to explore the hydrology and geochemistry of Boulder and South Boulder Creeks. Topics will include flood frequency and hazards, aqueous geochemistry of the watershed, and potential impacts of invasive species, nonpoint source pollution, and emerging contaminants on stream ecology.
This field trip follows the GSA guide published from the 2007 GSA Annual Meeting in Denver (available at http://fieldguides.gsapubs.org/):

Through the Generations
The tradition of Rocky Mountain geology remains strong at all scales, spatially and temporally. This volume fosters that tradition with its collection of peer-reviewed papers associated with the 2010 GSA Annual Meeting in Denver, Colorado. Spatially, this volume discusses theories of continental mountain building events in tandem with microscopic observations and parts per billion trace element concentrations. Temporally, the volume covers geologic history from the Precambrian to modern issues of climate change and energy, groundwater contamination, geologic hazards, and landscape evolution. Many of the trips propose new interpretations of famous geologic ideas and environs such as Laramide deformation, the Colorado Mineral Belt, the Lewis and Clark Line, the Chalk Cliffs, and Garden of the Gods.
