From abstract: The Howe-Wilburton district is a narrow area of about 540 square miles that extends westward from the Arkansas State line for about 60 miles across Latimer and Le Flore Counties, Okla. It lies in the southern part of the Arkansas Valley physiographic province and is a part of the large Arkansas-Oklahoma coal field.

From abstract: The McAlester district is an area of about 477 square miles in Pittsburg, Atoka, and Latimer Counties, Okla. It lies entirely within the Arkansas Valley geomorphic province except for the extreme northwest corner, which is crossed by the easternmost cuesta of the Osage Plains province.

From abstract: The Quinton-Scipio district includes about 450 square miles, mostly in Pittsburg County but partly in Haskell and Latimer Counties, Okla. The stratified rocks exposed at the surface in the district are the McAlester, Savanna, Boggy, Thurman, Stuart, and Senora formations, of Pennsylvanian age, and consist of alternating beds of shale and sandstone with some coal beds and a few beds of limestone less than 1 foot thick. The total thickness of these formations exposed in the district is between 3,000 and 3,300 feet. There are probably unconformities at the base of the Savanna sandstone and at the base of the Thurman sandstone. Overlying the Pennsylvanian formations in parts of the district are unconsolidated sand, gravel, and clay, which in part belong to the Gerty sand, a deposit in an abandoned Quaternary (?) river channel. Other unconsolidated deposits include sand on stream terraces and Recent alluvium.

From purpose and scope: The purpose of this report is to describe the hydrology of Brazil Creek basin in the vicinity of Red Oak and to assess the potential hydrologic effects of surface mining based on data collected between October 1978 and September 1981.
