Description

The name Earlville Sag was applied to a barely discernible depression trending east-northeast from the crest of the Peru Monocline. Scanty subsurface data on Cambrian and Ordovician horizons were used to define the sag. The name is discarded because the feature was so poorly defined, and it is not shown on newer maps based on more data.
