Title: Hale Mountain Section in Northwest Arkansas

Author(s): Albert W. Giles (2), Eugene B. Brewster (2)


The Hale Mountain section in the southwestern part of Washington County in northwestern Arkansas has long been known and has been visited by many geologists. It is the type locality for the Hale formation and the Morrow group. The easy accessibility of the section and its completeness warrant a detailed description of the formations that comprise the section. These formations range from middle Mississippian to early Pennsylvanian, and include the upper part of the Boone limestone, the Fayetteville shale with the Wedington sandstone member, and the Pitkin limestone, all of Mississippian age; as well as the Hale formation, Bloyd shale with the Brentwood limestone and Kessler limestone members, and the basal part of the Winslow formation, all of early Pennsylvanian age. The ccessibility and length of the section, its geographic and geologic location, and a description of the formations, including detailed stratigraphic sections, are considered.
