I visited the area around Leeds recently, and came across this sign [pdf] by the Leeds Geological Association, on the Chevin.
The Chevin is a ridge in the West Yorkshire landscape, formed over thousands of years. The surrounding area is mostly a valley (one of the “dales” of the Yorkshire Dales) formed by prehistoric rivers and glaciers.

I wasn’t expecting to encounter any science on this trip, so the geology sign was a surprise. Fittingly, I found it at “Surprise View”, the highest point of the Chevin.
