For those of you with Missing 411 tendencies, you may be interested to note that there is a small lake a little less than four miles west and a tad north of the campsite called, "Devil's Lake." Happened to see it while scouring the maps of the mines in the area. I had never heard of Missing 411 until this week. (I'll NOT be reading that anytime soon - I go camping way too much and would be paranoid.) The more I dig, the more I'm thinking old mine tunnel.
