Mining has been historically important in the Picuris Mountains. The
Harding Pegmatite Mine was operated off and on from about 1900 to 1958, when it was donated to the
University of New Mexico as an outdoor geological laboratory. At one time, the mine made New Mexico the leading producer of
beryllium among the United States. Copper has been mined at Copper Hill north of the Harding Mine. Other commodities historically mined in the range include
tungsten, optical
calcite,
bismuth, and
aluminosilicates. , the MICA mine was the only producer of
muscovite west of the
Appalachian Mountains. ==See also==
