Big Jacks Creek
 Big Jacks Creek is a 58-mile (93 km) long tributary of Jacks Creek in Owyhee County Idaho. Beginning at an elevation of 5935 feet (1809 m) north of Riddle it flows generally north and slightly east through the arid Big Jacks Creek Wilderness before reaching its mouth southwest of Bruneau at an elevation of 2779 feet (847.0 m). In 2009 35.0 miles (56.3 km) of the creek were designated as wild by the Omnibus Public Land Management Act which also created the Big Jacks Creek Wilderness.
