Big Jacks Creek is a 580NaN0 long[1] tributary of Jacks Creek in Owyhee County, Idaho. Beginning at an elevation of 5935feet[3] north of Riddle, it flows generally north and slightly east through the arid Big Jacks Creek Wilderness, before reaching its mouth southwest of Bruneau,[4] at an elevation of 2779feet.[2] In 2009, 35miles of the creek were designated as wild by the Omnibus Public Land Management Act, which also created the Big Jacks Creek Wilderness.[5] [6]
