my standard bluetop peanutbutter jar. Note: the fence was added to keep out the ATV's after the stampsand restoration. There is a person opening to allow people in.
Quincy started reclamation in 1943 after failing to make a profit in its underground works. Early stampmills were around 75% effective. In the 1920's new milling methods (grinding, floatation, and leaching) were adapted to all mills. With these new methods, it was found that significant amounts of copper had been discarded with the stampsand. This was Quincy Mining Co's reclamation mill. Stampsand was pulled up from the lake by the dredges and sent here. Here it was processed by the newer methods. Look to the water and you'll see what little remains of the shore plant. The circular rails allowed the pipe from the dredge to move as the dredge changed position.
Note: Please re-hide container as it should be. I'm told this area is used by paintballers, who occasionally do "cleanups". I set this with a piece of metal as a shield, and came back and found the shield moved to the side. Please re-hide as found. Note: This cache was probably stolen and destroyed in Oct 2015. It was either "found" with 2 others in the area or targeted. Please re-hide carefully.
