This geologic field trip focus is somewhat atypical but arguably reflects an ongoing evolution within the geosciences. Instead of traveling out into rural settings to look at outcrops and the stratigraphy exposed, or rural landforms and their geologic history, this field trip is focused on built and engineered environments in the Omaha area and the ‘modified’ associated geologic processes such as surface and groundwater flow, weathering, and soil formation. The ongoing evolution includes an increase in a multidisciplinary system science approach and is driven by a need to address environmental and resource management challenges using new tools and conceptual frameworks. One example is the concept of the critical zone, the zone encompassing the vegetation canopy down to groundwater. This framework is crucial to understanding endeavors at Glacier Creek Preserve and provides an example of an application of a system science approach and the role that technology plays. These topics are also part of the environmental geology courses we teach at UNO where we explore the interplay between geologic knowledge and human endeavors.

Field trip introduction: The sub-discipline of urban geology looks at surface and near surface geologic processes, landscapes and deposits and considers how they have been modified by human activity in urban environments and how they influence design of the built environment. With a > 60-year record of associated publications, the field of urban geology is aligned with engineering, public health, emergency management, planning and much more. This one-day field trip will focus on examples of Omaha’s urban geology and place it in the even larger discussions on the Anthropocene (a proposed addition to the geologic time scale).
