sinks

these are depressions found in various areas of ky. usually they will contain small pieces of charcoal and bits of metal in bottom this is how it works when you have various types of ores sulfides , hydroxides , carbonates , or oxides they must be roasted to drive off sulfides or oxygen when sulfides are present they must roasted in open air when the others are roasted they must be in an oxygen free invirement so they dug a hole they made shelves placed logs at different levels this alloyed them to achieve either process depending what type ore was available when carbonates , oxides , or hydroxides were roasted the ores were below ground level sulfides were above in open air oxides , carbonates , and hydroxides require carbonic acid to convert to the metalic state after this is achieved the heat is increased by bellows to melting temps. this in turn runs into bottom of hole it is then claimed after fire is quenched and sent to smelt.

Is there a way to determine the difference between them and a typical sink hole from a collapsed cave? Other than a metal detector? Several creeks in the Red River Gorge I have noticed collapsed cave systems in their headwaters.

thats is one thing some people believes that is what they are if you poke around with a long pole and it is solid bottom usually they are not over 5 feet deep use caution and common sence if investigating actually do not knowany other way.

Thanks, a 5ft hiking stick will have to do out there!

Any similarity to a pine tar kiln?

have no clue not familuar with that

KY and Ohio also have many old charcoal pits. Turning most of our old growth Appalachian timber into charcoal for the old iron furnaces. You will need to make sure you are not locating one of those-but they were not usually in the woods lie the sinks RGB1 mentions.
