Slinde Mounds State Preserve contains ancient Indian mound burials in some hill prairie. About 32 acres (130,000 m2) in extent, it is on a terrace above Canoe Creek, a tributary of the Upper Iowa River, and is approximately six miles from Waukon, Iowa in Hanover Township, in Allamakee County.
The state acquired the land in 1979. Since 1989 listed on the National Register of Historic Places. It receives its name from the family who sold the land to the state.
It is located in the Driftless Area of Iowa, a region which escaped being glaciated during the last ice age. It is adjacent to the Canoe Creek Wildlife Management Area and the Upper Iowa Access hunting area.
