On the east side of Apache Junction, and right at the edge of the greater Phoenix metropolis, there is Lost Dutchman State Park with its landmark view of Superstition Mountain.
Lost Dutchman is named after a legendary gold mine, supposedly started by a local family in 1840, and then developed by a Dutch immigrant (Jacob Waltz), who left no records of its location.
Many people have tried but failed to find the mine and nearby caches of gold, somewhere in the Superstition Mountains a few miles east of the state park.
