The Mustansaarenkeidas has been created through the overgrowth of small lakes and ponds and the swamping of forest land. The shape of the mire is complex, which is why the surface structures of the mire in the area are very versatile. In the central part of the mire, there is a nearly 7-hectare Lake Mustajärvi.
The area's raised bogs have a clear surface structure. A large part of the paths in the area are peat-surfaced and impassable. Because of this, the swamp area is the most difficult to navigate in the Geopark area. In the Aapasuo sections, the structure formed by ridges and ponds is found, which is typical of northern aapas.
