Malham Tarn

Cloud reflections in Malham Tarn, Malham in the Yorkshire Dales.
A lake in limestone country is unusual, but Malham Tarn has a base of impervious Silurian slates. In the 19th century, Lord Ribblesdale raised the water level with a dam and sluice gate at the southern end. At 377 metres it is the highest lake in England.
Malham Tarn House (on the opposite bank) was often visited by Rev. Charles Kingsley and the tarn was his inspiration for the 1863 novel, ‘The Water Babies’.
