Description

The West Salem Dome was mapped on the basis of two control points, one of which Easton later found to be in error. (See Supplement to Illinois Petroleum 46, "Revised Structural Data Eliminating the West Salem Dome"). This is the only known example in Illinois of a structural feature expunged by its own author.
