Riley Rocky Stone, a twelve year old boy hiking on a family vacation in the Superstition Mountains of Arizona, finds what his grandfather tells him might be an Apache arrowhead. Riley has no idea his arrowhead possesses magic. He finds himself taken back one hundred and fifty years in history on a wild adventure back to the Superstition Mountains where he meets an old miner, Jacob Dutch Waltz. During his time with the Dutchman, as Jacob is called, Riley encounters U.S. Cavalry deserters, two bands of Apache warriors and an old rancher, Blind Charlie before he finds himself back home with a souvenir-a large gold nugget.
