Remnants of perennially frozen ground can serve as indicators of past climate changes. Evidence of ground ice like pseudomorphs, or solifluction lobes, for example, has helped us identify cooling events such as the last glacial maximum or the Younger Dryas. Cryogenic activity can also have wide ranging affects on the behavioral context of archaeological sites displacing material from its original location a few millimeters to many meters. Here I illustrate some common types of cryogenic features and provide examples from archeological sites in southern Siberia and Alaska.
