In The Footsteps of John Phillips Askrigg,
19th May 2022
Bill Fraser of Leeds Geological Association will lead a small group on an energetic tour of sites identified as Yoredale Cyclotherms by John Phillips at Mill Gill, Askrigg. Paths are steep and uneven. Rock surfaces close to the stream can be slippery John Phillips (1800-1874) was the first Keeper at the Yorkshire Museum and was Secretary to the YPS and the British Association for the Advancement of Science. Yoredale was the original name for Wensleydale carrying the river Ure. Phillips named the distinctive set of Carboniferous rocks which underlies the series of terraces the Yoredale Group. These sit on the Askrigg Block and demonstrate up to eleven cycles of sedimentation called cyclotherms.
Transport will be by own vehicles and the party will be a maximum of twelve. Good boots and protection from the weather is advised.
