How to Make a Rock Sled for Dredging
August 2017 by Ron Kliewer
When my “anonymous” friend told me the rock tub was probably a hundred miles from where he safely stashed it, I decided to build another sled and improve on my old design.
Early Summer Mining in Wyoming
Old tailing piles extend for miles. There was still plenty of water flowing here, so WPA members set up highbankers at several settling ponds.

Scams, Scammers and Schemes

Wyoming's Billion Dollar Nugget—The Trilogy Ends
With eight loads processed, a pumpkin-size rock fell into the hopper, stopping the whole operation until I could lift it out.
