A view of Higger Tor from Carl Wark |
Viewed
from Carl Wark, the plateau like Higger Tor – capped by the coarse, pebbly upper
leaf of the Chatsworth Grit – is 45 metres higher than the equivalent rocks that you
are standing on and cannot be accounted for by the dip of the strata. It is the
result of a fault that traverses the Burbage Valley and can also be seen in the
gritstone edge towards the southern end of Burbage Rocks.

By
the time that I had finished looking around Carl Wark, I was accompanied by
numerous other casual visitors, as well as the participants in a fell running race, and so I
walked quickly up to Higger Tor, noting a variety of other similar rocks, and stopped only very briefly to look closely at a soil horizon.
Somewhere
on my walk, presumably whilst steadying myself on one of the many slippery or
rocky slopes, muddy water had splashed onto my camera lens – much to my
annoyance.

Although
I noticed this when I sat down for a bite to eat, many of my views of Higger
Tor were spoiled – especially updates of those I had previously taken with
colour transparency film and which I have frequently used for publicity - and to illustrate various talks on the geology and architecture of South Yorkshire and the Peak District.
Everywhere
on this walk there is evidence of the powerful rivers that flowed into the deltas, which existed in Namurian times - and the all round views are
quite stunning. Boggy areas, with peat, cover much of the top of Higger Tor and
although I didn’t include this site as part of my walk - from a distance - the slumped shales found beneath the lower leaf of the Chatsworth Grit can clearly
be seen.
