5	Histels	"Organic soils similar to histosols except that they have permafrost within two meters below ground surface. They have 80% or more organic materials from the soil surface to a depth of 50 cm or to a glacic layer or densic, lithic, or paralithic contact, whichever is shallowest. These soils occur redominantely in subarctic and low arctic regions of continuous or widespread permafrost."	Gelisols	72	209	204	TAXOUSDA_Histels_250m_ll.tif
6	Turbels	"Soils that show marked influence of cryoturbation (more than one-third of the depth of the active layer) such as irregular, broken, or distorted horizon boundaries and involutions and areas with patterned ground. They commonly contain tongues of mineral and organic horizons, organic and mineral intrusions and oriented rock fragments."	Gelisols	67	212	210	TAXOUSDA_Turbels_250m_ll.tif
7	Orthels	"Soils that show little or no cryoturbation (less than one-third of the depth of the active layer). Patterned ground (except for polygons) generally is lacking.
