As we were hiking on the very top of the ridge, there was a grassy flat area that had all these sink holes in it. 
There is a whole are that looked as if a giant had made footprints in the soft earth...
The thing is, the grass is not dug out from the hole, and it is undisturbed except that it is sunken. Could it be a form of pingo? It's just a really weird area to have something this is frost heave related........very puzzling indeed.
