while in between there are intervals of blazing sunshine, under which the green fells turn bright yellow and orange in powerful contrast to the indigo shadows on every side. Such rapid changes from complete saturation to sudden heat are trying to the hardest rocks, and at Hardraw, close at hand, there is a still more palpable process of denudation in active operation. Such a morning as this is quite ideal for seeing the remarkable waterfall known as Hardraw Scar or Force. The footpath that leads up the glen leaves the road at the side of the ‘Green Dragon’ at Hardraw, where the innkeeper hands us a key to open the gate we must pass through. Being September, and an uncertain day for weather, we have the whole glen to ourselves, until behind some rocks we discover a solitary angler. There is nothing but the roughest of tracks to follow, for the carefully-made pathway that used to go right up to the fall was swept away half a dozen years ago, when the stream in a fierce mood cleared its course of any traces of artificiality. We are deeply grateful, and make our way among the big rocks and across the slippery surfaces of shale, with the roar of the waters becoming more and more insistent. The sun has turned into the ravine a great searchlight that has lit up the rock walls and strewn the wet grass beneath with sparkling jewels. On the opposite side there is a dense blue shadow over everything except the foliage on the brow of the cliffs, where the strong autumn colours leap into a flaming glory that transforms the ravine into an astonishing splendour.

It is possible to walk behind the fall on a slippery spray-drenched path.]
