Named for its unique shape, Horseshoe Mound is a rare example of a driftless area mound and one of the most prominent and scenic geologic landmarks in Jo Daviess County. Located at the eastern gateway to the historic city of Galena and less than a mile east of downtown, it has survived the pressures of development. Horseshoe Mound is now permanently protected through a joint effort of the Jo Daviess Conservation Foundation and the Natural Land Institute. Funding for the purchase came from grants from the Illinois Clean Energy Community Foundation and the Doris Duke Charitable Foundation. The Natural Land Institute holds a conservation easement on 28 acres adjoining the property.
