Fullux Posted June 19 Share Posted June 19 Howdy all, This is an odd looking rock I found in my usual deposit of the Drakes Formation here in Louisville, Kentucky. It looks to me to be pumice, added by the fact that it's very light, but after doing a quick search, I found that igneous rocks are extremely rare in Kentucky, and out of the few mentioned, pumice was not one of them.

hemipristis Posted June 20 Share Posted June 20 You won't find pumice in KY. Pumice is an extrusive igneous rock, and there haven't been any volcanoes in that part if the world in a very, very long time, If it is indeed pumice, its been brought in, Pumice is common to see in lawn and garden departments of hardware stores as ornamentals. Is it very light? Does it float? Pumice floats 'Those who cannot remember the past are condemned to repeat it.' George Santayana Link to comment Share on other sites More sharing options...
