This collection contains test-hole cores through surficial sediments and shallow bedrock drilled by the Nebraska Geological Survey (Conservation and Survey Division), the Nebraska Department of Roads, the U.S. Army Corps of Engineers, and other organizations, including bedrock cores drilled by petroleum and mineral concerns.
A portion of the cores in this collection originated from oil producing areas and areas with potential petroleum development within the Panhandle region of western Nebraska. These cores were drilled by oil companies between 1950-1969 and were later donated to the Nebraska Geological Survey (Conservation and Survey Division). With the assistance of the National Geological and Geophysical Data Preservation Program (NGGDPP), some of these cores have been rescued from deterioration.
Curation work on this collection continues and additional metadata will be added as it becomes available.
