"Ice Age' frozen 'permafrost' illustrating an 'Ice Wedge' within the permafrost as a 'clear ice' deposit within the actual wind blown silts of the last Pleistocene.  Occasionally, mummys are discovered within these ice wedges, as they become sublimated (dehydrated) and erode out during thaw.  Sometimes rarely, larger mammals such as Steppe Bison or Mammoth may be exposed.  Some of these ice wedges are melt ponds (prior to freezing) and animals may fall into them and freeze to remain frozen during the Ice Age periods at a minimum of 10,000 years."
