What's a frost-gley? I've noticed this term in a book about Pleistocene East Europe. It's apparently a soil which was formed during the interstadials, but that's all my book says, and I can't find much more on the internet. So what more can be said about frost-gley, preferably with sources?
A frost-gley is a waterlogged permafrost soil. IOW, a gleysol that has undergone cryoturbation.
