A small road-fill quarry. This location has produced large numbers of excellent quartz crystals. Many crystals are found as floaters, having been shattered from the matrix and later healed by continued growth. Tabular crystals are common and Faden crystals have also been found. Nearly all of the crystals are colored orange to red due to iron staining.
