Description

Using scanty data from mines and boreholes, Moulton (1925) inferred the presence of a structural high centered in Section 22, T10N, R2E. He called it the Nokomis Dome, although his map indicates no closure. Payne and Cady (1944) using a few more control points, likewise found no structural closure, but applied the name Nokomis Arch to an anticlinal nose trending slightly north of east in eastern Montgomery County.

Few new data have become available since Payne and Cady's report. A new map (Nelson 1987b) of Herrin Coal Member structure does not confirm a dome or anticline similar to those of the earlier reports. A structural high on my map near the center of T10N, R3E, is based on a single control point and provides insufficient evidence for naming a structure. Use of the name Nokomis Anticline should be discontinued.
