Cheyenne Gold 

Rusty Sabin had mined the ill-omened gold in the Sacred Valley of the Cheyennes, a place so holy that even the air was feared by the Indians. Born of white parents, Rusty had been raised by the Cheyennes. To them he was Red Hawk, a leader and a great warrior. But the gold he carried from the valley was to bring terrible ordeals to Rusty and to the tribe.
