Mine Info
Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments
Comment (Environmental Factors): THE LAS TABLAS CREEK MINES, PARTICULARLY THE BUENA VISTA AND KLAU MINES, ARE ACID MINE DRAINAGE PRODUCERS. CONTAMINANT DISCHARGE FROM MINES IN THE LAS TABLAS CREEK WATERSHED IS NOT UNIFORM THROUGH TIME AND IS RELATED TO SEASONAL CYCLES, ACTIVITY AT THE MINES, AND OTHER FACTORS. THE LOCATION OF CONTAMINANT PLUMES MIGRATING DOWNSTREAM, PARTICULARLY WITH SEDIMENT, CAN THEREFORE BE HIGHLY TIME DEPENDENT. MEAN AND MAXIMUM CONCENTRATIONS DETECTED IN WATER FROM THE ENTIRE LAS TABLAS CREEK WATERSHED DURING SAMPLING 1992 WERE COMPARED TO 1993 STANDARDS. MAXIMUM CONCENTRATIONS OF TOTAL COPPER, TOTAL CHROMIUM, TOTAL IRON, TOTAL LEAD, TOTAL MERCURY, TOTAL NICKEL, TOTAL ZINC, TURBIDITY, ALKALINITY, SODIUM, CHLORIDES, AND BORON EXCEEDED A VARIETY OF HUMAN HEALTH, FISH AND WILDLIFE, AGRICULTURAL, PLANT, AND NUISANCE STANDARDS.
