Name Origin

The Vergennes Sandstone Member of the Spoon Formation (Shaw and Savage, 1912, p. 7) is named for Vergennes, Jackson County.

Type Section

The type locality is near the town of Vergennes (N 1/2 11, 7S-3W).


The name Vergennes has not been extended beyond the type area, and recent studies by T. K. Searight suggest that the Vergennes may be equivalent to the Palzo Sandstone.

Extent and Thickness

The outcrops indicate that the Vergennes is a channel sandstone at least 30 feet thick, but units above and below it are poorly exposed and its stratigraphic position is in question.
