Llangollen

Carboniferous Limestone scenery heaven! About a mile north of Llangollen, the Eglwyseg escarpment presents some really fantastic views. What’s more, among the huge amount of scree that covers its scarp slope, fossil brachiopods and corals can be found.

DIRECTIONS

♦ Parking is found approximately three miles north of Llangollen at the northern end of the escarpment.
♦ From the car park follow the road to your right downwards to the ford and then follow it west. As you walk you will see scree on the slopes and where safe this can be investigated in search of fossils.
♦ Walk along the path until it descends to the road. From here you can turn around and retrace your steps or you can walk back to the car park along the road.

PROFILE INFO

FIND FREQUENCY: ♦♦♦ – As a great thickness of Carboniferous Limestone strata can be investigated along the escarpment, it is not surprising that fossil types and abundances vary from place to place. In some areas finds are very low, in others they are higher.
CHILDREN: ♦♦♦ – There is a well marked path along the side of the escarpment but in places this is thin and there are fairly steep slopes to one side. The scree can be loose, so children should be well supervised.
ACCESS: ♦♦♦ – Fossils are found along a well marked path but to fully investigate the location a walk of several miles is required. The path and the nature of the scree will not appeal to everyone. The car park at the northern end of the escarpment can be difficult to find from Llangollen.
TYPE: – Fossils are found amongst scree on the sides of the Offa’s Dyke Path, on the escarpment’s scarp slope.

FOSSIL HUNTING

The Eglwyseg escarpment is approximately 4 miles long. However, the portion of the Offa’s Dyke Path from which the scree can be explored is only half as long, as the path follows a road at the base of the escarpment’s southern end.

From the car park at the northern end of the escarpment, follow the road to your right downwards to the ford and then follow it west. As you walk you will see scree on the slopes and where safe this can be investigated in search of fossils.

The most common fossils to be found are brachiopods and corals. These will be more abundant in some areas than others.

Walk along the path until it descends to the road. From here you can turn around and retrace your steps or you can walk back to the car park along the road.

GEOLOGY

The Carboniferous Limestone Series at Llangollen is of Visean age. It is part of the Clwyd Limestone Group, This is around 330 million years old. This is a diverse range of limestone facies with subordinate sandstone and mudstone units, and exhibiting local dolomitisation. Records the initiation and growth of a carbonate platform along the northern flank of the Wales-Brabant Massif.

SAFETY

This is a remote location and, as such, visiting singularly is not advised. Mobile phone signals may be lost in this area, so it is important that you tell someone where you are going and what time you expect to be back. Some areas of scree may be unstable – you should not attempt to climb any steep areas. As the walk is fairly long, taking refreshments is definitely recommended!

EQUIPMENT

This is a Site of Special Scientific Interest and, as such, no hammering should be carried out. If you are going to collect specimens you will need a bag and packing material, but please keep collecting to a minimum. Sturdy walking boots are required, along with a drink and a snack as the walk is fairly long. A camera will come in handy as this is a very beautiful location.

ACCESS RIGHTS

This site is an SSSI. This Special Site of Scientific Interest, means you can visit the site, but hammering the bedrock is not permitted.
