Porter Sculpture Park is located just off Interstate 90 in Montrose, South Dakota about 25 miles west of Sioux Falls. It is on the the South Dakota Drift Prairie. There are many weird sculptures placed in Porter Sculpture Park. Many of the sculptures, in the style of industrial art, were made with scrap metal, old farm equipment, or railroad tie plates. The largest sculpture in the park is a 60 foot tall bull head. This sculpture took three years to build, weighs 25 tons, and is equal in size to the heads of Mt. Rushmore. Lets take a look at some stunning pictures of these bizarre sculptures taken by Mykl Roventine a photographer belongs to West Saint Paul, Minnesota, United States.
