Hamilton County is located in North Central Texas, an area of extensive agricultural development, moderate population, and relief of suffleient magnitude to facilitate geologic investigation. The purpose of this survey was to determine the sequence, thickness, areal distribution, and lithic nature of surface rooks and to describe the geomorphio relationships in the county, only brief note being taken of paleontology and structure. The following formations of the Trinity, Fredericksburg, and Washita groups are present in Hamilton County: Travis Peak, Glen Hose, Paluxy, Walnut, Comanche Peak, Edwards, Kiamichi, and Duck Creek. This study indicated no major stratigraphic or structural anomalies in the area. The economic framework of the county coincides closely with the areal distribution of the rocks of the Comanche series.
