Long Description:
These kilns were constructed using local sandstone, and were of two different styles. Three were beehive or cone shaped and nine were shaped like tubs with iron reinforcing bands. Each of the styles were approximately 30 feet by 30 feet in size and used nearly an acre and half of hardwood with each firing cycle which took on the order of a week and a half.

Though it seemed at first as if the supply of hardwood was inexhaustible, it only took seventeen years from when they were built in 1879 for all the hardwood to be cut. Closed in 1896, the kilns today are mostly piles of rubble with a few sections of wall still standing. All traces of the other buildings that supported the kilns have disappeared.
