Standing at above sea level, it is at the western end of the Grampian Mountains in the Lochaber area of the Scottish Highlands, close to the town of Fort William. The mountain is a popular destination, attracting an estimated 100,000 ascents a year, around three-quarters of which use the Pony Track from Glen Nevis. The cliffs of the north face are among the highest in Scotland, providing classic scrambles and rock climbs of all difficulties for climbers and mountaineers. They are also the
Mountain range strata were removed by erosion over the core of the mountain range and spread as sand and clays across the Great Plains to the east. This mass of rock was removed as the range was actively undergoing uplift. The removal of such a mass from the core of the range most likely caused further uplift as the region adjusted isostatically in response to the removed weight. Rivers are traditionally believed to be the principal cause of mountain range erosion, by cutting into bedrock and transporting sediment. Computer simulation has shown that as mountain belts change from tectonically active to inactive,
