Hi, Kingpointnorth,
This is an exceptional selection of permafrost failures/ regressive thaw phenomena. Some of them are as impressive as the melting of glaciers. Did you find these permafrost failures with Google Earth or did you just use GE to map them? Of course they are part of the natural dynamics of permanently frozen sloping or eroding landscapes and it would be interesting to know if the regression has accelerating in the last 30-40 years. Do you have an answer?
I am studying a few of your sites on various satellite imagery and older aerial photographs. Do you have more information on your Red Marked site?
