Abstract

The 2021 Nebraska Geological Society field trip will provide an overview of the geology and hydrogeology of northeast Nebraska, the groundwater quality and quantity issues unique to the region, water management issues and decision-making, and ongoing work relating to water quality and geologic (hydrostratigraphic) framework, along the lower Niobrara and Missouri rivers Between Spencer Dam and Homer Nebraska. This program will be comprised of an auto tour with multiple stops on Saturday October 16 through Monday October 18 as illustrated in Map 1. The tour will begin with an examination of the Spencer Dam site and several locations in and around Niobrara State Park. Day 2 will see participants visiting water infrastructure and aquifer framework projects in the region, as well as locations with outstanding geology and features from geological hazards (flooding and landslides). Participants will complete the trip by examining a Carlile Shale outcrop south of Vermillion, SD, visiting a historical site with geological significance, and conclude by examining older sedimentary strata found in Ponca State Park and an outcrop of Dakota Sandstone in Homer, NE with a discussion relating to its significance as an aquifer in eastern Nebraska.
