We have already covered the Eastern Kentucky Coal Fields and Mountains, The Knobs, and The Bluegrass. Now it's time to cover The Pennyrile, The Western Kentucky Coal Fields, and The Jackson Purchase. These three are the "plains" of Kentucky. There are hills, though they aren't as large as those in the rest of the state. There are large, flat spaces used mostly for farming. There are tracts of forested land, karst topography with numerous caves, and lots of water and marshland. Let's wander a bit!
Our first stop is one of the largest of the physiographic regions of Kentucky: The Pennyrile (or Pennyroyal). This region borders all of the others except for The Bluegrass (which ONLY borders The Knobs). It is surrounded on most sides by escarpments and hills of some kind. The Pottsville Escarpment and Muldraughs Hill to the east and the Dripping Springs Escarpment to the west and north. The cities of Bowling Green, Elizabethtown, and Radcliff all call this region home. While these cities are steeped in history (especially Civil War and frontier history), the true treasure of this region is below the ground. Underlying much of the forests and fields is a large expanse of karst terrain, that wonderfully pockmarked area of limestone known for its caves, sinkholes, and disappearing streams. The longest cave system in the world, Mammoth Cave, is located in this region occupying a large portion of Edmonson County. There are numerous other caves and formations throughout the region. Even today, scientists and cave explorers are attempting to add to the 367 miles of explored passages that make up Mammoth Cave and are even trying to find links to the other cave systems in the region.
Up next is the Western Kentucky Coal Fields. This is an area of the state that I admittedly have little knowledge of. The largest city in this region is Owensboro which sits on the Ohio River just south of Evansville, Indiana. The claim to fame of this area is that is was home, at least for a time, of John James Audubon, the man for whom the Audubon Society is named. He lived for a while in Henderson, Kentucky. He is known for his drive and desire as a naturalist to draw and catalog all of the species of birds in North America. Today, it is possible to tour the John James Audubon State Park in Henderson. Many of Audubon's original oil paintings and drawings can be seen as well as hiking interpretive trails and viewing the area wildlife.
Finally we come to the far western edges of Kentucky, an area of lakes, marsh, and rivers known as The Jackson Purchase. With Paducah as its largest city, the Jackson Purchase is the smallest of the six physiographic regions of Kentucky. The small area is home to a large amount of diversion, however. The area is dominated by The Land Between The Lakes. This is a National Recreational Area located between two of the largest of the Tennessee Valley Authority waterworks: Kentucky Lake and Lake Barkley. These two lakes were formed when the Tennessee and Cumberland Rivers were damned in the early 1900's. The resulting inland peninsula (the largest in the United States) became a natural choice for recreation. It is a natural ridge with numerous forests and lots of history. Surrounding these lakes and permeating throughout the area of various lowland marshes and wetlands. This small region is also where the Ohio River empties into the Mississippi. One other small note; there is a small part of Kentucky that is divided from the rest of the state by the Mississippi. This area, the westernmost portion of Kentucky, can only be reached by traveling south into Tennessee and around the bend in the river. This oddity of geography is also near where, in 1811-1812, the New Madrid Fault slipped causing 3 earthquakes in less than 2 months, all of which were between 7 and 8 on the Richter Scale. These quakes were strong enough to wake people in New York, crack sidewalks in Washington, DC, and ring church bells in Boston. The quake also make the Mississippi appear to flow upstream for a time and created Reelfoot Lake in Tennessee. The fault runs under Kentucky in this region and could still have long lasting effects should it ever slip in the future.
So ends out brief sojourn into the lands that make up Kentucky. If there was too much science, tough, I like science. It is also important to understand these aspects of the land in order to understand the culture which has helped to create. In future writings, I will go into more detail about these regions, why they are well known, and what they have to offer. From marshland to mountain, plains to forests, caves to fault zones, Kentucky has a little of everything.
