The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Location): ALONG CLEAR CREEK AT PECOS ST. ; INFO FROM LAND.ST :(1974)
Comment (Commodity): PLACER GOLD WAS RECOVERED AS BY-PRODUCT OF WASHING/SCREENING OF SAND AND GRAVEL FOR CONSTRUCTION AGGREGATE
Comment (Workings): DRAGLINE-OPERATED PIT
Comment (Development): COYLE STATES, "A UNIQUE FEATURE OF THE PLANT, WHICH HAS CONSIDERABLY LOWERED THE COST OF REMOVING THE WASTE MATERIAL FROM THE GRAVEL AT THIS PLANT, IS THE INSTALLATION OF STRIPS OF CARPET IN THE FLUME WHICH CARRIES THE WASTE TO THE DUMP. GRAVEL AND SAND OF THE CREEK CARRY VALUES OF ABOUT 5? PER CU. YD. IN FLOUR GOLD, AND THIS IS COLLECTED BY THE CARPET IN THE FLUME AND WORKED OFF AT INTERVALS."
