A short 5 mile walk starting at Cassop, a small village with a history of quarrying and mining but is now pastoral and agricultural in an elevated position overlooking the Durham countryside. The route was accurately described as easy low level paths, tracks and roads.
Leaving the village we followed the path through the vale along side a pond locally known as the Bogs a product of mining subsidence. The area is a nature reserve filled with flowery grassland and thorny thickets. Orchids, bird’s-eye primrose, blue moor grass, wild thyme and cowslips flourish in the rich magnesium limestone soil.
Unique to this area is the northern brown argus, a butterfly found only in eastern Durham, where it feeds on the abundant common rock-rose, also a fan of magnesium limestone.
Heading along a quiet lane towards the lovely little hamlet of Old Cassop a brown butterfly was spotted, we stood perfectly still until it settled and very obligingly it rested while we took our photographs. It turned out to be a speckled wood brown and not the elusive brown argus!
Walking towards Quarrington Hill we had extensive views across the Durham countryside with the Cheviots, Pennies and North York Moors seen in the distance but we soon dropped down to Cassop and lunch at The Three Horse Shoes.
