"Smoky quartz and other pegmatite minerals are found at Sentinel Rock and Specimen Rock, two prominent granite outcrops located three miles west of Colorado Springs near the junction of High Drive and Gold Camp Road. In 1885, George Frederick Kunz described Sentinel Rock and Specimen Rock as Colorado's "richest area for quartz", and noted the recovery of thousands of smoky quartz crystals from one inch to four feet in length. .... For information about restrictions, contact the nearby Bear Creek Regional Park Nature Center." from 'Colorado Rockhounding' which includes a site photograph and map.
