Description

Lee (1915) defined the Macoupin Dome from subsurface mapping of the Herrin Coal Member (Pennsylvanian). Easton (1942) used more control points when he mapped the same horizon. Easton's contour map shows nosing, but no closure. Nelson's (1987b) map also indicates no dome in the area; therefore, use of the name should be discontinued.
