Where to Find Quartz in Wisconsin

Wisconsin quartz comes from three main settings. The Mineral Point area in the southwestern lead-zinc belt (Iowa and Lafayette counties) yields small quartz crystals in dolomite vugs alongside galena and sphalerite. The Door Peninsula in Door County produces calcite-quartz geodes in Silurian dolomite, with crystal interiors up to fist size. Central Wisconsin pegmatites in Marathon and Wood counties carry smoky quartz and rose quartz in granite cores. The Ableman's Gorge area near Rock Springs in Sauk County adds drusy quartz on Cambrian sandstone. Most Wisconsin quartz is small but well-formed; surface collecting concentrates on quarry dumps and roadcuts.
