Description

Easton (1942) used borehole data to map a small kidney-shaped area of closure on the Herrin Coal Member. Several of the key wells Easton used to define the Thayer Dome have questionable records. Remapping using additional control points fails to confirm the existence of a dome (Nelson 1987b).
