Gordale Scar is a limestone ravine 1 mile (1.6 km) north-east of Malham, North Yorkshire, England. 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. A right of way leads up the gorge, but requires climbing approximately 10 feet (3 m) of tufa at the lower waterfall.
