Proceeding northeastward from the West Tennessee geanticline, no 
strata older than the Mississippian are encountered until the Wells 
Creek Basin, just southwest of Cumberland City on the Cumberland 
River, is reached. Here a local uplift exposes strata as old as earhest 
Ordovician. Foerste has studied this area and the following section 
is compiled from his notes.*. In this the identification of the Dixon 
and Brownsport limestones is of particular interest, and the general 
section is apparently that prevailing in the Tennessee River Valley.

In East Tennessee and in the Appalachian in general, Niagaran 
strata proper are wanting, with the exception of several small areas 
near Sneedville, Hancock County, Tennessee. In his Geology of 
Tennessee, Professor Safford described the occurrence of the Meniscus 
limestone, giving it the special name Sfieedville limestone, in the 
4 Journal of Geology, XI, 1903, p. 690.
