An Arctic Equivalent of the Grumusol
Describes soils near Umiat, Alaska: the gilgai micro- microrelief, sparse vegetation, and the desiccation cracks of considerable depth and width underlying a surface mulch of mineral soil aggregates. At depth, the soils grade into a thick structureless viscous clay which overlies permafrost. The for...
