Walk-on geology maps, past and present

To celebrate the bicentennial of William Smith’s pioneering geological map of England, Wales and southern Scotland in 2015, the Yorkshire Philosophical Society and the York Museums Trust commissioned a walk-on geological map installation of Yorkshire in the Museum Gardens at York. This impressive 4 x 4 m mosaic by artist Janette Ireland used geological materials to demonstrate many of the important points illustrated by Smith. Details of the map including explanatory leaflets can be found at https://www.yorkmuseumgardens.org.uk/the-mosaic-map/. This however is not the first walk-on geological map installation in the county.
