Guide to Treasure in Tennessee by Henson?

[Kimbrough]

Anyone have a copy of this book handy? I need some help. I will be passing thru Knoxville in the next day or so and was wondering if anyone could tell me where to look for the overhanging cave with a wooden box in it. I remember reading it is off the highway and could be seen with binoculars form the road. I just thought it'd be interesting to see If it is still there. Thanks for any help you can give.
