Geocache Description:

This is an unexpected Karst pond. It is fully visible from the safety of the sidewalk - please admire from this vantage point only.

Karst topography is a landscape created by groundwater dissolving sedimentary rock such as limestone.

This creates land forms such as shafts, tunnels, caves, and sinkholes. Groundwater seeps into and through these land forms. The result is a scenic landscape which is beautiful but fragile, and vulnerable to erosion and pollution.

Beautiful and fragile - do not cross the fence! It would be dangerous to cross the fence onto the privately owned property that the Karst sits upon. The earthcache feature and requirements are all accessible from the sidewalk area. Photos encouraged.

To obtain credit for this Earthcache, you must email me:

1. While standing at the coordinates, give the estimated depth of the karst wall from the top of the water to the top of the south wall.

2. Tell me how a karst POND typically is formed. Please do NOT tell me how a karst is formed, I already told you that above .....

From the Kentucky Geological Survey at the University of Kentucky:

Where Is Karst Located in Kentucky?

Kentucky is one of the most famous karst areas in the world. Much of the state's beautiful scenery, particularly the horse farms of the Inner Bluegrass, is the result of development of karst landscape. The karst topography of Kentucky is mostly on limestone, but also some dolostone. The areas where those rocks are near the surface closely approximate where karst topography will form.. The bedrock is millions of years old, and the karst terrain formed on them is hundreds of thousands of years old. In humid climates such as Kentucky; you should assume that all limestone has karst development, although that development may not be visible at the surface.

The outcrop area of the limestone bedrock in Kentucky has been used to estimate the percentage of karst terrain or topography in the state. About 55 percent of Kentucky is underlain by rocks that could develop karst terrain, given enough time. About 38 percent of the state has at least some karst development recognizable on topographic maps, and 25 percent of the state is known to have well-developed karst features. Some Kentucky cities located on karst include (in the Inner Bluegrass) Frankfort, Louisville, Lexington, Lawrenceburg, Georgetown, Winchester, Paris, Versailles, and Nicholasville; (in the Western Pennyroyal) the communities of Fort Knox, Bowling Green, Elizabethtown, Munfordville, Russellville, Hopkinsville, and Princeton; (in the Eastern Pennyroyal) Somerset, Monticello, and Mount Vernon.
