Description

Willman and Payne's (1942) structure map of the Colchester Coal Member (Pennsylvanian) showed a shallow depression with a curving southeast-trending axis. Closure of 20 to 30 feet (6-9 m) was indicated. Jacobson's (1985) structure map of the same horizon was based on many more control points indicating irregular depressions in the area, but nothing that can be properly called a syncline. Use of the name Stavanager Syncline should be discontinued.
