The entrance to Gordale Scar (Scan from 1989)

Gordale Scar is a limestone ravine 1 mile (1.6 km) northeast of Malham, North Yorkshire, England.[1] It contains two waterfalls and has overhanging limestone cliffs over 330 feet (100 m) high. The gorge could have been formed by water from melting glaciers or a cavern collapse. The stream flowing through the scar is Gordale Beck, which on leaving the gorge flows over Janet's Foss before joining Malham Beck 2 miles (3 km) downstream to form the River Aire.[2] A right of way leads up the gorge, but requires climbing approximately 10 feet (3 m) of tufa at the lower waterfall.
