This geological process results in namesake lobes which are tongue-shaped debris masses often classified as stone-banked or turf-banked; extensive areas of them result in namesake sheets. These lobes form on slopes and plateaus such as those of the Ruby Range in the Yukon Territory. This process is indeed most often associated with environments underlain by permafrost; it is generally faster than 
This geological process results in namesake lobes which are tongue-shaped debris masses often classified as stone-banked or turf-banked; extensive areas of them result in namesake sheets. These lobes form on slopes and plateaus such as those of the Ruby Range in the Yukon Territory. This process is indeed most often associated with environments underlain by permafrost; it is generally faster than creep and results in more unitary flow of soil. FTP, name this form of mass wasting which happens when overlaying soil thaws out, becomes waterlogged, and slides downhill over underlying frozen soil.
