Ingleton has long been a
popular and important place for geology and geography
field trips.One practical point is that it is easily
reached by a great many schools and colleges,
and the terrain can be safely visited by even
quite small pupils if a little care is exercised.
The
geology can be explained quite simply. There
are layers of Carboniferous age sedimentary rocks
that are nearly horizontal, sitting on vertically
folded slaty rocks of Palaeozoic age or older. These
slaty rocks form a very solid block of crust,
and are bounded to the south by the Craven wrench
fault system.
Examples of local rock can
be found at The Rock Shop, Ingleton (pictured

Within the Carboniferous
rocks, the Millstone Grit, the Yoredale cyclothems
and the Carboniferous Limestone. They can all
be easily examined, and they contain fossils,
sedimentary structures and widely differing lithologies.This provides plenty of scope for very
basic study as well as for more advanced work.
The slaty rocks below have
been highly folded and partly recrystalised by
large earth movements.
They were then eroded by the encroaching
Carboniferous Sea.Thus, we see a classic Angular Unconformity. The
solidity of the basement rocks meant that the
Carboniferous beds were largely undeformed by
subsequent tectonic events, with movement along
the Craven Faults being the major structural feature
of the region.Again, there is scope for both a very elementary
examination of the relationship of the various
geological units as well extremely complicated
lithological and structural studies in the basement
rocks.
For
the Geographer and Geomorphologist, these abrupt
changes in Geology lead to many interesting and
easy to study landforms.Furthermore, the various phases of past
glaciation expands the number of landforms to
be studied, especially as it has lead to many
different glacial deposits forming such as the
Norber Erratics near Austwick.Subsequent rejuvenation has further expanded the possibilities
for study.Once again, there is plenty to see at all
levels of study.
Erosion of the limestone
has lead to the creation of potholes and caves.Whilst educational studies of such systems
should be approached with the greatest caution,
there are two excellent show caves in the area-both
worth a visit-where many features can be easily
and safely observed.
Ingleton has a good range
of low cost accommodation for field groups and
has a down to earth friendly environment that
goes well with school and college groups.The walking is not strenuous, and there
are plenty of well-marked paths as well as the
famous Waterfall Walk.
