Exposure of metamorphic rock typical of the exposrues in the immediate area of Stop 5. This rock is crystalline mega-breccia of possible slump origin but may also be related to a central rebound area of the impact crater.

Although the outcrops along this road are now partly covered with vegetation, the irregular distribution of the foliations in the fragments of the individual schist pieces can still be seen. Commonly they are at right angles to the foliation in the adjoining rock. Some of the individual blocks are small, less than 30 cm in diameter, whereas others appear to be very large, several meters in diameter. During their initial studies in this area, Neathery and others noted fragments of schists surrounded by sediments that resembled those of the Eutaw and Gordo Formations and those of the Mooreville. The area of schist fragments appears to cover approximately 200 acres in this area. No rock material suitable for thin section study could be found that might add to the current paucity of shock data.
