Vertisols can form in ultra-continental environment with negative MAST Vertisols of ultra-continental environment are polygenetic soils Cryogenic attributes formed earlier, while vertic features are younger. Formation of vertic features started when depth to permafrost increased and the soil started to shrink/swell Gelert suborder and Vertic subgroup are proposed to Haplogeloll
