. It rises to and is classed as a Munro. Schiehallion has a rich botanical life, interesting archaeology, and a unique place in scientific history for an 18th-century experiment in " weighing the Earth". It is near the centre of mainland Scotland. The mountain's popularity amongst walkers led to erosion on its footpath and extensive repairs were undertaken in 2001.

The view of the broad eastern flank attracts many visitors to the shores of Loch Tummel. Schiehallion is sometimes described as the centre of Scotland, as it lies only 5 km west of the centre of gravity of mainland Scotland. The folk group '' Gaberlunzie'' sang a song "The Back of Schiehallion", meaning Scotland.

Geology

The majority of Schiehallion consists of quartzite, a rock formed from an original sand by heat and pressure. Quartzite is a white or pinkish rock, in which the dominant mineral is quartz. People often mistakenly think that Schiehallion is an extinct volcano because its shape is reminiscent of an active volcano; in fact, it was formed by sedimentary processes and the shape is the result of erosion by ice during the ice ages.

History

The slopes of Schiehallion have been inhabited and cultivated since the first millennium BC until approximately two hundred years ago. Schiehallion has been used for grazing sheep and stalking red deer. Since 1999 the eastern side of the mountain has been owned by the John Muir Trust.

The Schiehallion experiment

Schiehallion's isolated position and regular shape led it to be selected by the English astronomer Charles Mason (of Mason–Dixon line fame) for a ground-breaking experiment to estimate the mass of the Earth in 1774. The deflection of a pendulum by the mass of the mountain provided an estimate of the mean density of the Earth, from which its mass and a value for Newton's

''G'' could be deduced. Mason turned down a commission to carry out the work, and it was instead coordinated by the Astronomer Royal, Nevil Maskelyne. He was assisted in the task by mathematician Charles Hutton, who devised a graphical system to represent large volumes of surveyed heights, later known as contour lines.

Footpath

A Munro mountain, Schiehallion is popular with walkers due to its accessibility, ease of ascent and views from its summit. An estimated 17,500 to 20,000 walkers made the ascent in 2000. Most walkers start from the

car park at Brae of Foss, which lies just outside the boundary of the John Muir Trust estate. The route, which initially heads southwest before turning west to follow the main ridgeline of the hill, is about in length. Ben Nevis, the highest mountain in the British Isles, can be seen to the west from the summit of Schiehallion. By 1999, when the John Muir Trust bought the estate, the main path had become exceedingly eroded by the passage of many thousands of walkers. The scar was visible from quite a distance. The organisation therefore decided to construct a new path, following a different line, better able to handle the pressure of visitors.
