There's a company that's trying to sell what initially appears to be a piece of property with a cave that "likely connects" to Jewel Cave in South Dakota for $1,999,999.00.
http://sunsetvalleymining.com/Otherclaimsforsale.html Only they're selling the mining claim, not any actual property. And the cave doesn't connect - wrong rock unit. They will give you GPS coordinates to the cave entrance, for serious parties only. To show your interest you need to have a certified check for 10% of the total cost of the property.
