A 100ft-wide sinkhole that is so deep you can’t see the bottom has opened up in County Durham.
The gaping void, thought to be the result of mine workings deep beneath the surface, is just a stone’s throw from a couple’s farmhouse.
It was three times smaller when it was first discovered on Thursday morning, at Cowshill, in the rural area of Weardale, by Durham University academic Sam Hillyard, but more earth has since collpased.
Sam, 39, had been out shooting rabbits with her black Labrador Jack and was returning to her home, Burtree Pastures, when she noticed the 30ft hole.
Overnight, the hole sank further to reveal an abyss. And it is feared rain forecast for over the Bank Holiday may see it become larger still.
