The meander is about long and at its narrowest, its neck is about wide. The land within the bend and on its right bank is part of the Lower Brule Indian Reservation, while the land on the left bank is part of the Crow Creek Indian Reservation. The Lewis and Clark National Historic Trail passes through Big Bend.
