Description

The Littleton Anticline is a relatively short fold (6 mi, 10 km) that strikes northeast and shows relief of 50 to 100 feet (15-30 m). Mapping of the anticline on pre-Pennsylvanian horizons was based on outcrop and borehole information (Wanless 1957). An unpublished structure map of the base of the New Albany Group shows about 60 feet (18 m) of closure on this anticline (R. Howard, ISGS, unpublished mapping). A structure map contoured on the top of the Galena Group shows eastward nosing but no closure in T3N, R2W (Howard 1961).
