"This tradition appears to have completely died out. I asked many old inhabitants of the place if they had ever heard such a story, but it was quite new to them.
The scene of the tragedy is not, however, very difficult to identify. There are very few 'hidden pools' in this part of the stream; it is mostly a shallow, brawling brook. I have carefully tracked the stream from Donnerdale Bridge to Ulpha Bridge, and can only find two places which at all answer to the description given in the sonnet. One of these is opposite the 'Traveller's Rest' inn, the other, is a little higher up. This latter is a deep and placid pool, situated half way down a curious corridor, known as 'Long Dub,' where the stream flows for some distance in a straight line between walls of rough mountain slate, the strata having been tilted almost at right angles to their natural position. Here a little rill tumbles into the Duddon by a miniature cascade, and the pool is sheltered and darkened by oak and beech—a not unlikely spot to have inspired the sonnet." (Herbert Rix.)
