Iowa County
The Wisconsin River gravel bars near Muscoda carry Lake Superior agates and quartz transported south by glacial outwash, giving the Driftless Area a rare source of free public collecting. Under Wisconsin's public trust doctrine, the beds of navigable rivers below the ordinary high-water mark are held open to the public, and surface-picking loose stones from sandbars is broadly permitted. Access is through public boat landings, with the exposed gravel bars richest at low summer water.
