The Glenn Formation is the only Pennsylvanian exposure in Oklahoma south of the Arbuckle Mountains. This exposure, which covers one hundred and sixty square miles more or less, is located in Carter and Love counties in the vicinity of Ardmore. The sediments of the Glenn are strongly folded and stand practically on edge over the greater part of the area. While in the employ of the Empire Gas and Fuel Company, the writer assisted by C. J. Wohlford, measured a number of sections across these sediments.

The sediments consist of shales, sandstones, limestones and conglomerates, and a total thickness of approximately nineteen thousand (19,000) feet.

In this paper an attempt is made to differentiate and classify this massive formation into its component members, and to correlate these rocks with those of the same age north of the Arbuckle Mountains, and with the Pennsylvanian rocks of Texas.

Considerable detail was made in the study of the structure of the Glenn Formation. Axes of anticlines and synclines were carefully located as most of the work was done with plane table.

A brief description of these folds, together with their relation to other buried Pennsylvanian folds in the region is given.
