Description

The Dwight Anticline, a subtle feature, was mapped as lying 25 to 30 miles (40-48 km) east of and approximately parallel to the La Salle Anticlinorium. Mapping of various Cambrian and Ordovician horizons by Willman and Payne (1942) indicated the Dwight to be an anticlinal nose (no closure) with maximum relief of about 200 feet (60 m). Continuity of the structure is suspect because Willman and Payne had so few control points. The Dwight Anticline is not recognizable on Bristol and Buschbach's (1973) structure map on the Galena Group or on Jacobson's (1985) map of the Colchester Coal Member. Use of the name Dwight Anticline should be discontinued.
