Underground Trips
This is the draft
programme – check back for updates
Limestone Mines
The first few trips are into limestone
mines, once common throughout central Scotland and Fife. The lime industry flourished for over two
hundred years, only closing down after World War Two. The uses were :-
-
agricultural lime
-
lime for mortar and building
work
-
road bottoming
-
flux at iron foundries
-
purifying agent in gasworks and at Bo'Ness
pottery manufactory
-
building.
TRIP 1 - Leven Seat
Mine

A pillar and stall ('stoop and room') excavation of limited extent
in West Lothian. The rock carries some good fossils in places but little remains of the accompanying buildings. Parking is at a layby on the A706, with a half km
walk-in along a green track,
presumably laid during mining although stone was removed by rail from the site.
Trip Duration approx
1 ½ hrs
Party size 10 persons
TRIP 2 - Bowden Hill Mine

An interesting series of passages situated in a hillside east of
Linlithgow, West Lothian. Worked by the
Bowden Lime Company, the mine ceased operation 1900-1901. Various stone buildings and a large single vent draw kiln are still visible in the
fields by the mines, and a small pillar and stall mine lies on top of the
hill. Essentially, the workings
consist of a number of adits, running straight into the hill for 250 metres, stone being removed from long, low
galleries supported by props.
Passages have suffered from extensive collapse leaving rugged crawl ways and interesting boulder chokes to be navigated. Through trips are possible between three open
entrances. Bowden Hill has been used by the GSG for over
forty years as a training ground for new cavers. It offers excellent sport and
in one or two obscure chambers houses
beautiful displays of ” aragonite
helictites”. Very little active collapse has been noted during this
period, although one fall did occur sometime
in the 1990s which blocked off one of the exchange routes, forcing
visitors to find and use an alternative route.

TRIP
3 - Cults Limestone Mine, Cupar, Fife

An
extensive underground system, with some roads bricked with steel girder roofs
dating from the 1940s. The main workings have little sense of order, with rows of pillars departing from the straight due to a
search for good rock One or two roads still carry relics
of steel ore buggies and rails
and an assiduous search might well throw up other relics. Due to a police criminal search in the
1980s, passages near to the surface carry a bewildering array of coloured
cords festooned around pillars with little apparent logic!
Trip Duration approx
2hrs
Party size 10 persons
TRIP 4 - Birkhill Fireclay Mine
CANCELLED -- BARRED OFF
Developed for public
access, these workings, which were very
extensive but now largely flooded, lie on either
side of the River Avon and at the top of the river bank are the remains of mine
buildings and machinery. The commercial mine is approached by crossing
a steel bridge over the river, but on the 'near' bank, beside the path are two
large openings into a smaller mine where a through trip can be made. It has no
artefacts but excellent displays of
flowstone and floor speleothems.
Trip Duration approx ½ hr
Party size 10 persons
TRIP 5 - Alva Silver
Mines

In
the 18th century an intensive mining operation in the hills above Alva,
Clackmannanshire, extracted quantities of high quality silver ore. Several
mines are visible within easy access of a
public footpath in Silver Glen. The downside is that, following a recent survey
of the mines and subsequent
publication, all the horizontal adits have been blocked off by the Woodland
Trust who oversee the land. The mine
the largest in terms of overall entrance, is still accessible by
climbing over the railing shown. A steep slope down leads to a short climb up
into a horizontal adit, gained via a section of railway line jammed across the rift. There are eleven identified workings (two of them
are 20ft shafts communicating with levels having a bottom entrance) and most are clearly visible due to fencing
and warning notices. The mines ceased operation in the late 18th
century. 1 They
were re-worked in 1880 and again at the beginning of the 20th century for ancillary minerals but nothing profitable
was found.
Trip Duration approx
2 hrs
Party size 10 persons
TRIP 6 - Hilderston
“Silver” Mine, Cairnpapple, West Lothian
Although situated close to the site of medieval silver mining,
this adit is thought to be an attempt to gain lead or other minerals from the
area at a later date. The mine consists of some 100 metres of passage. The
inner section is permanently flooded and a trip to the end of the mine is only
possible by wading in neck deep water. No artefacts visible. If there has been
prolonged wet weather the entrance may be sumped by a surface lake in the
bottom of an open cast limestone working.
One for the “enthusiast” - Very Wet
Trip Duration approx
½ hr
Party size 10 persons
TRIP 7 -
Linhouse Water Shale Mine

A shale mine which may
be quite safely explored. is a short, grid patterned working on the Linhouse
Water near Mid Calder which extends for a short distance into the hillside
before either ending at blank
walls or in one case, descending to a flooded section. The air is clear and
movement very easy although its situation right beside country park paths means
there are no artefacts of any description inside. The GSG recently conducted a
clean up of this mine, removing
litter and other junk to restore the passages
to a pristine condition.
Trip
Duration approx ½ hr
Party size 10
persons
TRIP
8 - Philpstoun No 6 Shale Mine (the Dunnet Shale Seam Workings)

This
has a shallow entrance which leads to the first level gallery follow able for 100
metres. All further sections of this mine are now flooded but high in the roof
of the sloping passage are the remains of a winch and haulage cable
Trip Duration
approx ½ hr
Party size 10 persons
TRIP 9 -
Whitequarries Shale Mine

The shale mining industry in
West Lothian was a huge undertaking, commencing in 1851 when James Young and partners developed a method to distil oil from
cannel coal and produce paraffin. At its zenith the industry employed over
10,000 men and changed the face of West Lothian for ever. Vast red coloured bings still dominate the
landscape, telling of enormous underground excavation generally in an area extending from the River Forth between
Linlithgow and Edinburgh south to Tarbrax and Addiewell. The earliest shale workings were open cast but
following the seams required inclined
mining. Twenty-five mines were in
operation by 1925, but access to many
of these has been frustrated by landscaping.
One extremely large mine, the Philpstoun near Abercorn, Linlithgow,
still possesses open entrances. Here
galleries are punctuated by steep drops
to lower levels where 'cundys' or massive areas of deliberately collapsed rock, the result of longwall mining, may be
seen (but not entered!) Tentative
exploration by the GSG in 1999 reached
a fourth level down before bad air (carbon
dioxide?) terminated work. It is thought that close below that level invading sea
water has flooded the mine, whose
lowest level is 430 feet. This
means there must be an outlet for this water
Trip Duration 1 ½ hrs
Party size 7 persons
TRIP 14 -
Tyndrum Lead Mines

To visit these sites requires
extended travel time - some 2 hours - to the small community at Tyndrum, north west of Crianlarich. Mining occurred here as early as 1428
possibly due to the high silver content of the lead won. Main mining ceased
about 1862 although the spoil heaps and mines
were further reprocessed in 1916. A series of 13 excavations may be visited high
above the town, some of them mere blocked shafts, others offering several
hundreds of metres of passage.
