Geology

An Teallach from Sail Mhor, Fisherfield Forest (Route 74)

Much of the early pioneering work in geological theory was based on investigations on the rock formations of NW Scotland. This is recognised in the UNESCO-endorsed award of Geopark status to the North-West Highlands. Geopark designation is intended to encourage geotourism, and a number of excellent visitor centres as well as roadside information boards have been developed to encourage this. This Geopark area is undoubtedly the most scenically attractive area in the UK.

The North-West Highlands contain rock formations which span over 3000 million years of earth history and include some of the oldest rocks in the world. Along the west coast, the oldest rock in the region, Lewisian gneiss, creates a landscape of low hills and scattered lochans. Rising from this gneiss landscape are huge masses of Torridonian sandstone, capped by quartzite, which form the distinctive mountains Cul Mor, Suilven, Canisp and Quinag within the Geopark as well as the mountains of Fisherfield, Torridon and Applecross further south-west.
