In the area of this map, the Kentucky River is one of the main recreational features with several parks, nature preserves, and numerous trails (e.g., Buckley Wildlife Sanctuary, Raven Run Park, and several Nature Conservancy holdings, Fort Boonesborough State Park). Some of the geologic processes leading to its formation are discussed in the section below.
The Kentucky River in central Kentucky is at the bottom of a deep gorge (see shaded relief map at right, part of Wilmore 7.5-minute Quadrangle). However, the meandering shape of the river is typical of rivers formed in very flat landscapes. The meandering shape of the river was formed when it was at the level of the top of the gorge (before the gorge was formed). Over geologic time, the meandering river cut down through the bedrock preserving the meander shape. This feature is called an "entrenched meander." Deposits labeled as "High-level Fluvial Deposits" (shown on the map in bright yellow) are traces of the Kentucky River when it flowed on the flat terrain above the level of the gorge, at a time before the gorge was formed. The Dix River (empounded to form Herrington Lake) has had a similar history to the Kentucky River (it also has entrenched meanders, and high-level terrace deposits).
Where the Kentucky river cuts through the thick limestone and dolomite of the High Bridge Group (north of the Kentucky River and Lexington fault systems), a very scenic cliff-lined gorge known as the Kentucky River Palisades was formed. The Kentucky River Fault System appears to have affected the river in a significant way. Along the eastern side of the map, the Kentucky River flows to the northwest. Where it encounters the Kentucky River Fault System, the river changes course and flows to the southwest, parallel to the fault system. It flows in this direction for about 20 miles (as the crow flies) where it once again resumes its northwest course to the Ohio River.

The Kentucky River (difficult to see) at Clays Ferry, looking downstream from the Clays Ferry I-75 Bridge. Note the Kentucky River Fault in the far bank (cut bank) at the middle of the photograph. The upthrown side (with Tyrone, Oregon and Camp Nelson formations) is on the right and Lexington Limestone is exposed on the downthrown side to the left. Note the entrenched meander bend, the steep cut bank and the broad floodplain on the pointbar bank. Ford 7.5-minute quadrangle. 26 KB image, 164 KB image. |
