Three Peaks can all be seen and, on a clear day, there is even a glimpse of the sea at Morecambe Bay. A common feature of many Pennine dales and Lake District fells are the groups of cairns on the high ground. There is a fine cluster of ‘stone men’ on The Nab of Wild Boar Fell — and a smaller group on subsidiary peak, Little Fell ( at , to the north. There seems little agreement on when, why, or by which people such cairns were built. (One common suggestion, that they were built by shepherds as markers for paths, may explain some of the cruder ‘piles of stones’; but groups like those on The Nab are ambiguous.)
