Land sculpture

I have been going further East these past few weeks on a weekly basis and drive through this landscape. If I was a better photographer or had realised the new camera was in fact in my bag, the view would be more detailed. It's quite a strange scene because there are lots of telegraph poles and wires but also various land forms.
I need my Roman expert to tell me what it all is but maybe it just has something to do with the coal mining industry of the past.?
Still, I managed to capture a wee hint of blue sky.
