On 9 January 1903, President Theodore Roosevelt signed a bill (U.S.C., Title 16, Sec 141-146) to create Wind Cave National Park (WICA) (NPS 2011). The boundaries of WICA were extended in 1931 (U.S.C., 6th supp., title 16, sec. 141a), 1946 (16 U.S.C. 141a), 1978 (92 Stat. 3467) (P.L. 95-625), and 2005 (119 Stat. 2011) (P.L. 109-71) (NPS 2011a). Today, WICA encompasses 11,451 ha (28,295 ac) and is visited by greater than 600,000 people each year."
