No problem at all. I am wondering how all of this is still here? According to the states geological website, a lot of the stuff I'm finding shouldn't be here. Examples: anthracite coal, colonial coral, volcanic rock. The propriety is out in the middle of nowhere, high elevation, 400-500 feet above average. You can see for miles up here. I dug a deep hole on the far opposite side of the property to compare and see what is down a few feet. I hit sand and what appears to be scoria. Also, to cover the foundry slag theory, that is not even a possibility with the location and history. I can safely rule that out
