Greenish-gray sideritic and glauconitic clays in the upper part, and a fossiliferous marl in the lower part. These fluviatile sediments were deposited in brackish and marine environments. Driskill Mountain lies in the Sabine Uplift, a flat-topped dome in northwestern Louisiana and adjacent Texas, which rose as the younger coastal plain sediments around it subsided.

Soil Series: Darley gravelly fine sandy loam. Moderately deep, well drained, acidic, brown to red lateritic soil. Clay-rich red clay subsoil very slippery when wet.
