Stac Pollaidh, Scotland

Stac Pollaidh rises near Assynt in the northwest Highlands of Scotland. Its name means "peak of peat moss," and it consists of Torridonian sandstone, more than 500 million years old. Hillwalkers commonly call it "Stack Polly."
The rugged top of Stac Pollaidh suggests that the glaciers of Ice Age Scotland never covered this peak—that is, it was a nunatak. A similar example in Antarctica exists in the Southern Cross Mountains.
