This is the first listing in Terry's treasure atlas for Wyoming. In the past I never found anything on it. But my wife took over the research end of things and did find something. An old article on Jardine and Crevasse mining in Montana tells of a fishing hole and how to get there. On the way was an old prospectors cabin and told of his placer mine. The park moved it borders two miles north and ended the placer operations! The miner was not named Briggs, could some lost mines be due to the formation of the park? It will be a while till we develope our Wyoming book(s), maybe more will turn up by then.
