Unsorted polygons dominate the area south of Lake Latnjajaure and forms pentagonal or hexagonal polygons which transform into sorted forms were clasts are more abundant. The size of the individual forms range from 2 to 7 m with a mean at 3.5 m. The polygons are partly covered by vegetation and peat in the wetter parts and many forms have mud boils on the fine domains. Mud boils in different sizes are very common on the windswept moraine ridges and thufurs cover parts of the delta north of Latnjajaure and a small area 400 m south from the station. Sorted patterned ground exists in three types in this area.
Sorted polygons are frequent on the valley floor and becomes unsorted at the edges.
This type is less common at higher altitudes. Sorted circles dominate the area above 1200 m.a.s.l. Active forms can be found down to 980 m.a.s.l but only at snow patch sites. In several ponds and in Lake Latnjajaure a third type of sorted patterned ground is present which has an irregular shape and is associated with stone pits . Different periglacial slope forms are common in Latnjavagge.
