Howdy folks, Was typing with Woody about some of the local flint. I had mentioned to him that my wife likes the odd nodules from the Edwards Black Flint deposits to decorate her garden. I was out gathering a fifty or so for her for a project the other day. This deposit is downhill from where I park and hauling these back is not as fun as collecting them. Average size is ten pounds or so and I've seen them so heavy I can't even lift them. They appear to have formed when silica filled water created voids in the limestone and all have smooth white skins as opposed to our local porcelain Flint that looks similar but have a much rougher exterior. This stuff was very popular with the Amerinds too.....Mel Here's a pic of a couple of the lumpy nodules I brought back for the wife:

Toad: They are called Edwards Black but actually run from brown to gray to black. Some have lighter spots or included fossils but generally they are just opaque dark gray to black. Very fracture free and very hard and dense. Knapped without heat treating, they eat your copper boppers up in no time at all.....Mel

Mel: The British flint forms like this as well. Makes a good identifier for old ship wrecks since many ships were ballasted with flint. Probably the culls from gun flint knapping since most ballast flint is small.
