Description

Willman and Payne (1942) gave the name Morris Syncline to a structural depression that trends south-southeast and was mapped from sparse borehole data. About 50 feet (15 m) of structural relief was indicated. Willman and Payne interpreted the feature as having formed before deposition of St. Peter Sandstone (Ordovician) and not affecting younger strata. Mapping of the Cambrian Franconia Formation by Kolata et al. (1983) shows no syncline in this area, as indicated by Willman and Payne (1942). In fact, the northern end of this "syncline" corresponds with a dome on the map of Kolata et al. 1983; therefore, use of the name should be discontinued.
