Horse, I believe the hills in the Louisville area are primarily limestone. So I don't know if the hills were actually formed by glaciers, but the surrounding landscape might have been cut out of the hill from glacial waters. They are definitely not the morain type of materials.
As far as where there is or isn't gold in KY (or anywhere), as they say - gold is where you find it!
For getting started, you only need a gold pan, a sucker bottle to suck up whatever gold you find, and then something to put it into, like a vile. Wading boots and a hand trowel or shovel help, too! Search online, as you can find cheap pans and other accessories. There is lots of information available on techniques, where to look in a creek, etc online.
If you get out to do some prospecting, let us all know what you find. I plan to get out a bit this spring, so I will do the same on what I find.
In the meantime, I'm just taking advantage of some of the warmer days when the ground is thawed to swing the MD a bit. Found 62 cents in modern clad yesterday evening with about one hour of searching. I had searched in the same area a month or so ago and came up with a silver quarter and 7 wheat cents. Not that good of luck last night, though.
Good luck!
