The murder of Miss Thecla Gerken remains a mystery to this day. She was buried in the family plot at the Catholic cemetery on the outskirts of Woonsocket, South Dakota. Her gravestone stands next to that of her father, John E. Gerken.
Permafrost is soil, rock or sediment that is frozen more than two consecutive years. In areas not overlain by ice, it exists beneath a layer of soil, rock or sediment, which freezes and thaws annually and is called the active layer.xceptions occur in un-glaciated Siberia and Alaska where the present depth of permafrost is a relic of climatic conditions during glacial ages where winters were up to 11 Â°C (20 Â°F) colder than those of today.
Permafrost is any soil or rock that remains frozenâbelow 32Â°Fâthroughout the year. For a soil to be considered permafrost, it must be frozen for at least two consecutive years or longer.Permafrost can be found in cold climates where the mean annual temperature is less than the freezing point of water. Such climates are found near the North and South poles and in some alpine regions.ome soils in areas that experience warmer temperatures thaw for a short time during warmer months. The thawing is restricted to the top layer of soil and a permafrost layer remains frozen several inches below the surface.
