Valley at Malham Cove, Malham, North Yorkshire.
|
The valley at Malham Cove was formed at the end of the last ice age when the ground was frozen. The frozen ground meant that meltwater from the melting ice sheet formed a large river flowing over the surface, eroding the valley that we see today. The water from this river flowed over Malham Cove to form a huge waterfall.
When the climate warmed around 12,000 years ago the ground thawed and the river in the valley disappeared underground leaving the valley dry as we see it today. |
