They went up Little Langdale, I think, past the Tarn to Fell Foot, and crossed over the ridge of Tilberthwaite, into Yewdale by the copper mines.
Under a rock too steep for man to tread,
Where sheltered from the north and bleak north-west
Aloft the Raven hangs a visible nest,
Fearless of all assaults that would her brood molest.
There is a Raven crag in Yewdale, evidently the one referred to in this passage, and also in the passage in the first book of The Prelude (see vol. iii. p. 142), beginning—
Oh! when I have hung
Above the raven's nest, by knots of grass
And half-inch fissures in the slippery rock
But ill sustained, etc.
... toward the lowly Grange
Press forward,
To Waterhead at the top of Coniston Lake.
In connection with Loughrigg Tarn, compare the note to the poem beginning—
So fair, so sweet, withal so sensitive,
