It is often difficult to understand the context of folding in the Ouachita Mountains. Lack of outcrop continuity, lateral stratigraphic changes, and polyphase deformation interact to confound observers and interpreters and to make it especially difficult for instructors trying to teach in the field. This is particularly true in the internal parts of the range. A fold of unusual geometry can be observed north of the dike at the eastern end of Gray Lake. Retrodeformation of the outcrop shows that the fault is a thrust related fold that has been rotated into an unusual position.
