A former Ag-Au mine.
Maneotis, Fall 2009: The Master Key Mine lies at the entrance to the Little and Big Red Park areas of the Routt National Forest in the northern shadow of Hahns Peak in Routt County Colorado. Its location off the main county road has made for substantial collecting on the tailings over the years. Evidence of the main shaft has either collapsed due to structural damage or intentional back fill. Multiple collapsed structres are within the immediate area.
3 valid minerals.
