Abstract
Aerial photography has been employed to map stratigraphic and structural features in the Boston Mountains of Washington and Crawford Counties, Arkansas. Exposures of resistant stratigraphic units within the lower Atoka Formation were delineated on a series of large scale aerial photographs over an area of about 150 square miles. With the aid of a Bausch & Lomb Zoom Transfer Scope, the positions of the units were subsequently transferred to 1: 24,000 scale topographic base maps. The presense of east trending anticlines and synclines and a series of low displacement normal faults is reflected by either gradual or abrupt changes in elevation of the mapped units. The technique allows a substantial reduction in the amount of time and effort required to complete geologic mapping of such features.
