of the Vale of Lyvennet, the onward route now substantially forming a ring
around its headwaters.
The immediate onward route from the tumulus is along a grassy trod
through tussock grass to a limestone pavement. Beyond this a better path
that swings round to a couple of large granite erratic boulders, at the top
of a short descent to cross the infant Lyvennet Beck.
GRANITE BOULDERS
There are numerous 'alien' granite boulders, like those above Lyvennet Beck, dotted
about the limestone country of the north. Brought to their final resting place at the
whim of long-retreated glaciers, the larger ones, many with names, often serve walkers
as useful guides, while more than a few have in the past been used to delineate parish
boundaries.

wall, which is finally met at a wall corner.
CROSBY RAVENSWORTH FELL
Not far away, and reached by a deviation along the course of upper Lyvennet Beck,
stands a monument at Black Dub, claimed to mark the source of the Livennet (sic).
Erected in 1843, it more significantly commemorates the passage of King Charles II
who, in 1651, here 'regaled his army and drank of the water on his march from Scot-
land'.
The route here crosses Crosby Ravensworth Fell, designated a Site of Special
Scientific Interest. It is an important area for nature conservation, and home to a range
of moorland birds, some of which have declined significantly in recent years. Most not-
able of these are the golden plover, red grouse, redshank and curlew. These birds are
