From the start, head north until you almost reach water. Then,
head east. Follow the water for a short distance until it ends,
then head north. Go north until you see the American flag and a
building inside a fenced in area. The treasure chest is in there.
At the start of the level in roaming or racing mode, go in reverse
until you pass the train tracks. Then, go to the right until you
see a derailed train. Stop at the front of the train then go right
until you reach a canyon with a piece of road and two hills in the
middle. In between the two hills are two small houses. The
treasure chest is located in between the houses.
