Grayson County is part of theWestern Coal Field region ofKentucky.

The county lies in the Rough Creek Fault System, considered a potential hydrocarbon resource.[9]
Grayson County is home to twoU.S. Army Corps of Engineers lakes,Rough River Lake on the northern border of the county andNolin River Lake on the southeast border.
