Schiehallion
The view from Schiehallion 1083m (3547ft) looking over Loch Rannoch towards the mountains of Glencoe with Scotland’s highest mountain, Ben Nevis, visible on a clear day but cloud covered. (extra) The view on the way up looking across Loch Tummel towards Beinn a Ghlo and the southern Cairngorms.
Because of its location and shape (which appears like a cone from Loch Rannoch) the mountain became famous for the site of the first ever measurement of the mass of the earth by Neville Maskelyne, Astronomer Royal, in 1774. The calculation was based on the way that the mountain's own mass caused a pendulum to pull away from the vertical.  He also invented the contour lines that are used on maps today. (extra)
