Area of report is north-central TX, approximately between the Brazos and Red Rivers; in this area the Choza, Vale, and Arroyo Formations of Clear Fork Group of the Colorado River Valley of TX are not distinguishable. [Author maps Clear Fork Group undivided, except for "Merkel Dolomite" and "Bullwagon Dolomite", some sandstone beds, and "Lytle Limestone". Listed in descending order: Merkel is topmost member of Choza Formation, Bullwagon is topmost member of Vale Formation, and Lytle is a middle member of Arroyo Formation, all of Clear Fork Group of the Colorado River Valley.] Clear Fork Group is extensively covered by Quaternary deposits. Leonardian (Early Permian) Clear Fork Group is mapped in: Haskell and Knox Cos, Permian basin; Throckmorton and Baylor Cos, Bend arch; and Foard, Wilbarger, and Hardeman Cos, Palo Duro basin.
