Malham Tarn

Malham Tarn is a glacial lake near the village of Malham in the Yorkshire Dales, England. The lake is one of only eight upland alkaline lakes in Europe. At an altitude of 377m above sea level it is the highest marl lake in the United Kingdom. Its geology, flora and fauna have led to it being listed under a number of conservation designations. The site is currently owned by the National Trust, who lease part of the site to the Field Studies Council who offer residential and non-residential field courses there. The site was the inspiration for Charles Kingsley's 1863 novel, The Water-Babies, A Fairy Tale for a Land Baby.
