Figure 7. Hunton facies map with structural map of WCHF area, on the base of the Hunton Group / top of the Sylvan Shale. Structural features are represented generally by a southwesterly dip with north-northeast-trending faults, along with an east-west fault in the south. Cochrane Formation, dominantly limestone, is flanked to the east and northeast, as well as to west and southwest by dolomite of the younger Clarita Formation.
