Blue Mounds State Park, named for a long, high Sioux quartzite cliff, is located in southwestern Minnesota on the Iowa and South Dakota borders. The cliff, one and one-half miles long and up to ninety feet high, appeared to be blue in color to the early Euro-American immigrants who saw it from a distance. A unique herd of bison, the largest North American mammal, makes its home in the park on 533 acres of native tall grass prairie, which escaped plowing due to poor soil quality.
The last home plate used for baseball games at the Hubert H. Humphrey Metrodome in Minneapolis, Minnesota, before the stadium's demolition. The plate was used during amateur and youth baseball games between 2010 and 2013. The professional baseball franchise, the Minnesota Twins, left the "Dome" for their new home at Target Field in 2010 and took their final home plate to the new ballpark.
A section of turf used in the Hubert H. Humphrey Metrodome baseball field, near the center field sign reading "408 ft." The angled edge of this section met the permanently adhered center field turf. This piece was removed from the rolling track of the lower deck seating whenever the deck was lowered for football and other small (rectangular) field games in 2013.
