Pot Kiln
The round structure on the hill is a pot kiln where settlers burned limestone in the late 1800s. This burning changed raw limestone into lime for use as mortar to build fireplaces and fill chinks in log houses and to apply to farm fields as crop fertilizer.

During firing, a limestone arch covered the kiln and cords of hardwood burned underneath for 48 hours. As the temperature climbed to approximately 1800 degrees Fahrenheit, carbon dioxide escaped leaving lime behind. The kiln then cooled for another 48 hours.

Take a look! Lime from the last firing is still on the bottom. Notice how the kiln walls have melted due to intense heat.
