Field trip to the Campsie Fells
The Campsie Fells are a group of volcanic hills situated to the north of Glasgow and the jasper locality (approx 564 805) is in the Strathblane Hills above the small village of Blanefield. The approach to the locality is initially westward along metalled road and then we strike north-eastwards following a rough track then over open rough grassy ground following sheep tracks. The ascent is to 300m which is more or less the base of the small cliffs. Collecting can be done at the base of the cliffs by searching for fragments loosened from above by erosion. To observe the jasper in situ and collect from the volcanic rock requires a short walk along sheep tracks that pass between the stepped lava flows of the cliffs. The tracks are narrow and the grass verges slope at about 45° before meeting near vertical cliffs that range from about 5 to 10m high. Some scrambling may be involved in the gullies that cut the cliffs.
Conditions under-foot are dependant on weather conditions at the time. If dry the going is good, firm and commensurate with this ascent although some people may find walking poles of benefit. If wet then the ground becomes quite slippy in parts and extra care needs to be taken.
The walk in time should take about 30-40 minutes.
