The best place to park is on Mine Rd (also called Mesnard Location Rd) or you can park on the shoulder of US-41. There is a ditch which runs along US-41 so you will have to find a place to cross it.
The cache is a large container with room for large trading items.
The stone pile is what remains of a stone boat built during the Depression as a part of the Works Progress Administration (WPA) designed to provide work for unemployed people. The best known of the stone boats is located along US-41 in Kearsarge. The third stone boat is located in Centennial Heights. This boat has been forgotten, however the other two have been preserved and are well maintained.
