Abstract This is a guide to the key exposures of the Bowland Shale Formation present within the Craven and Edale basins of England, providing contrasting settings from respectively the northern and southern parts of the Craven Group extent. It provides a description of the evolution of the deposition of the hemipelagic mudstone-dominated components of the Craven Group during the Visean to early Namurian (Mississippian to early Pennsylvanian). It explains the significance of the chosen localities in understanding the development of the Bowland Shale Formation and gives details on the sections visible at the time of compilation, providing useful guidance for field visits.

Abstract The purpose of this one-day field trip is to look at the engineering geology and examples of geologic hazards along the western edge of the Denver Metropolitan Area. We will focus on the foothills of the Colorado Piedmont, an area that marks the transition between the Great Plains and the Front Range of the Rocky Mountains. The trip begins and ends in downtown Denver, at the Colorado Convention Center. We will travel northwest to Boulder, then south through Golden and the unincorporated suburbs of Jefferson County, and then return northwest to downtown Denver (Fig. 1). The trip guide contains narrative descriptions for 21 stops, twelve of which we will "roll by" for the GSA Annual Meeting field trip. Because of the dynamic nature of engineering geology, it is useful to look at past events as a means of planning for future development projects. In Colorado, the Colorado Geological Survey (CGS) has a statutory requirement to assist local governments with planning issues involving engineering geology. Since the early 1970s, CGS geologists have reviewed plans for hundreds of subdivisions along the Colorado Piedmont. The authors have provided emergency assistance and advice for incidents involving geologic hazards, as well as research and mapping of general geologic hazards (e.g., Soule, 1978) and specific hazards such as heaving bedrock (e.g., Noe and Dodson, 1997) for the CGS. The goal of this field trip is to provide an account of engineering-geologic factors that have affected the Colorado Piedmont in the past and will continue to do so in the future.
