Description

Easton's (1942) structure map of the Herrin Coal Member indicated a subtle eastward-nosing structural high, which he called the Hickory Grove Anticline. Remapping with more data indicates a very irregular structure with no definable closure or anticlinal nosing; therefore, use of the name should be discontinued (Nelson 1987b).
