Barron Co., Wisconsin, USA

Barron County Wisconsin in underlain primarily by poor-exposed Cambrian sandstones. In the northeastern portion of the county, the Blue Hills are ridges held up by pink to red Proterozoic quartzites. These have been locally quarried for building stone. The zircons noted in the mineral list are sand-sized "heavy mineral" grains from the quartzites. The quartzite also hosts thin layers of pipestone which have been worked by Native Americans since prehistoric times.

Glacial drift is thick in the County, primarily the result of deposition by the Wisconsinan Chippewa lobe. The dedicated collector can find interesting samples in the glacial drift including "drift" copper, banded iron formation and "Lake Superior" agates.
