NS3678 : Looking east along a rocky ridge with mounds

taken 13 years ago, near to Renton, West Dunbartonshire, Great Britain

Looking east along a rocky ridge with mounds
Looking east along a rocky ridge with mounds
The ridge has a number of small mounds along its length (the shadows cast by the low sun make them quite noticeable in this photograph). Its steeper northern side is undercut in several places, the result of small-scale quarrying.

This is a view east along the length of the ridge, which also extends a slightly shorter distance to the west from this point. For a view of the westward part of the ridge from the same location, see: NS3678 : Looking west along a rocky ridge with mounds.

In the satellite map linked from the end-note, this site is indicated by an orange marker pin, labelled "Outcrops 6". See LinkExternal link for a zoomed-in view that is centred on that marker.

The body of water that is prominent in the left-hand side of the photograph is Carman Reservoir. On the skyline in the right-hand side of the photograph is the escarpment that marks the edge of the Kilpatrick Hills. The houses of Bellsmyre nestle near the foot of the hills at the extreme right.
Carman Muir: outcrops and old quarry pits :: NS3778

See Link (in a Geograph article) for further information, and LinkExternal link for an annotated satellite view on which various features of geological interest (as well as traces of associated industries and other antiquities) are marked, as described below.

The topography of the parts of Carman Muir to the south of Cardross Road is determined to a large extent by cornstone deposits, which outcrop in places. Cornstone is an impure granular limestone, a fossil soil. Old quarry pits (probably worked before the nineteenth century) and possible test pits can be seen along the lines of these deposits; they are indicated by light blue marker pins on the annotated satellite view, and the cornstone outcrops are marked by orange pins.

This area, lying to the south of Cardross Road, exemplifies what the British Geological Survey refers to as the Kinnesswood Formation (see LinkExternal link at the BGS website for more information); this formation contains cornstone deposits.

Beside and to the north of Cardross Road are outcrops of sandstone rather than cornstone. The sandstone is best seen along a line of outcrops and pits beside the road (these are indicated by reddish marker pins on the annotated satellite view). Another prominent example lies at the ENE end of that line: a large disused red sandstone quarry, the old Fairy Knowe Quarry (later known as Carman Quarry) LinkExternal link at NS36967900. This area beside and to the north of the road exemplifies the Stockiemuir Sandstone Formation (see LinkExternal link at the BGS website for further details).

Both north and south of the road, the strata in this area generally dip at an angle of from 10 to 20 from the horizontal, descending towards the SSE; the Stockiemuir Sandstone Formation that is exposed beside and to the north of the road underlies the cornstone-containing Kinnesswood Formation to the south of the road.

The annotated satellite view also includes markers for various antiquities in the area:

● Ancient cairns: LinkExternal link
● Circular enclosure: LinkExternal link (originally reported as a hut circle)
● Carman (house): LinkExternal link
● Carman (enclosure): LinkExternal link
