Evening talk: “Geology of Otley Chevin”

Join the Friends of Chevin Forest on Tuesday 19th November to hear all about the Geology of Otley Chevin.

The Chevin is a north-facing escarpment comprised of shales and sandstones laid down 315 M years ago in the Carboniferous era. These rocks were deposited in a delta as part of a continent (Laurentia) in a tropical region by a southwards flowing river system which laid down the bulk of millstone grit deposits into a shallow, tropical sea. Initially low-lying of course, these were subsequently uplifted and faulted during the Pennine mountain-building period (or Variscan Orogeny) as the Iapetus Ocean (precursor to the Atlantic) closed.

Extensive quarrying on the Chevin enables us to see the geological features and informs our understanding of the soils that evolve from them and the ecosystems which depend on them. Bill Fraser, of West Yorkshire Geology Trust and author of the Chevin Geology Trail will bring these events to life and helping us to imagine the landscape so that we can bring expertise to underpin our understanding of the beauty of the area.

Join us from 7.30 pm on 19th November at the Black Horse in Otley for this evening talk.

All welcome – booking not required. This is a free event but donations to support the work of Friends of Chevin Forest will be gratefully received.
