Here are the coordinates and the email I received a while ago. The police have had this since April 2014, though I do not know if it was ever checked out.
I'm republishing now because it went up on Reddit last night and I'd rather a reader of this blog get there before some person who is unfamiliar with the ins and outs of this case does.
I should say, if you take this trip, please be careful. That is unforgiving wilderness and it is possible this is a bait for me. Please don't fall in a murder hole or something. And don't go alone.
Also, pictures, please.
