Flutes and fossils: Trowbarrow

Before heading off to North Wales last week I went to Trowbarrow quarry in Lancashire for a quick climb and poke about but haven’t had time to post about it.

This disused quarry is a geological SSSI with lots of high quality (and some crap!) climbing on offer. One of the most prominent geological features at Trowbarrow is the near vertical nature of the bedding planes. We can see this on the photo of the main wall where the routes follow cracks along the bedding. Other interesting geological features at Trowbarrow worth seeking out include; faults, folds, fossils and apparent paleo-karst.

The photo of the main wall above is actually one from a few years ago but it hasn’t changed much, except some people say that the entire right hand side of the main wall is rotating causing the cracks to widen? The climbs on the righthand side of the main wall are looking a little ‘unstable’ but I’m sure people can make their own judgements about whether to climb them…

Like many of the climbs at Trowbarrow Coral Sea (photo above) follows the bedding plane, and as the name would suggest numerous fossils are observable all the way up.

Another feature at Trowbarrow is Fluting. This is a common feature on limestone and is caused by differential weathering and erosion. It can be observed at Trowbarrow at the top of Assagai wall, where it forms the spectacular finish to Assagai (good sling runner in the flutes!).

In terms of the climbing the obvious mid grade classics Jean Jeanie(VS 4c), Coral Sea (VS 4c) and Assagai (HVS 5a) are certainly worth a look. Polish can be a bit of a problem at Trowbarrow (especially on Jean Jeanie!) but generally the climbing is really good quality!
