Sorry to have been so oblique. We have experienced what you describe in your last paragraph in Iceland. The snow/ice mass is solid on surface, but when you walk on it you break through that thin surface ice and encounter slush because of heat being transferred from warmer soil below.
The same thing happened to us in Svalbard or Spitsbergen isles above the north cape of Norway---slush a short distance below a solid snow/ice mass surface made walking difficult.
The above experiences have caused me to wonder about a real cause of the disappearance of the Arctic ice mass. A NOAA report I read several years ago dealt with great volcanic activity at ocean floor in the Arctic, warming/heating the water at those depths. That volcanic activity does not disappear with passage of time. That warm water circulates nearer and nearer to the bottom surface of the Arctic ice mass, causing melting of that ice from the bottom surface upwards. The above natural process is one mankind has no control over---
And it would not be affected by whatever activities mankind engages in to ameliorate "climate change."
Just a theory....
