The Loup River is more deeply entrenched than the Platte, which has a steeper gradient above its junction with the Loup east of the quadrangle. Mapping is continuing in the region and a more complete map of this area may eventually be produced. Acknowledgment of the U.S. Geological Survey would be appreciated in products derived from these data. Data were checked by the geologist that made the field observations. This map has been thoroughly reviewed for conformity with U.S. Geological Survey editorial standards and stratigraphic nomenclature.
Data are complete.
All geospatial database elements are attributed. The database files, metadata, and check plots were edited by the USGS Central Publications Group, and revisions made to the geospatial database as needed. Although this digital spatial data has been subjected to rigorous review and is substantially complete, it is released on the condition that neither the USGS nor the United States Government may be held liable for any damages resulting from its authorized or unauthorized use. Available as one printed sheet and 11-page pamphlet.
