Blue Jay Mine
This mine is part of the Greenhorn Mining District in Baker County. It lies directly on the boundary of the town site of
Robinsonville, beside Forest Service Road 940. There are five vertical shafts, one adit, and several pits belonging to
this mine. The adit was blown shut, and all but one of the vertical shafts were filled with water. Other than this, I do not

tailings pile. Note the milled wooden debris floating in the flooded shaft. (5/29/05)
