Geologist Dave Green joined us to explore the 300 million year history of Troopers Hill as told by the rocks that shape it. Warm spring sunshine welcomed us to the Hill, but we did experience one of the threatened showers part way round.

Having handed out a sketch of the Hill's geology and giving an introductory talk at our meeting point on the Field, Dave led us across to the Hill to look at the differents types of stone found there, including coal, mudstone & shale as well as the Pennant Sandstone which forms the bulk of the Hill and has been extensively quarried.

There was a very interesting discussion about why the underlying sandstone and coal measures result in acidic soils on the Hill.

The shape of the Hill is a result of its history, so inevitably that was also discussed, with even a brief mention of the 1888 smallpox hospital.
