Gold Discovery

Olmsted County · U. S. highway 52, crossing of the Zumbro River near Oronoco Post Office · location approximate

Directions to the area ↗

During the summer of 1856 discoveries of gold were reported along the banks of the Zumbro River in this vicinity. A lively gold rush, involving several hundred men, followed, and much panning and sluicing were done. Spring freshets and the panic of 1857 swept away the developments and with them Oronoco's gold prosperity.

Verbatim 1940 text, presented as a historical record, not current interpretation. Minnesota now calls the 1862 conflict the U.S.-Dakota War and has since replaced the wording on some of these signs.
