| Description | Rough geological colouring and notes by William Buckland, [1813-1820], on base map 'The County of Dorset surveyed by Isaac Taylor, reduced from the large map in six sheets...', published by William Faden, 1 July 1796. The key to the colours is in the hand of George Bellas Greenough. On the canvas backing is a short list of names and addresses of local contacts. Dissected on cloth, 2 miles to 1 inch. Box marked 'Dr Buckland's field map'. |
| Administrative History | The writing by George Bellas Greenough probably indicates that the compilation of this map is connected to the research for George Bellas Greenough's 'Geological Map of England & Wales' (1820). Greenough accompanied Buckland on a four day trip along the south coast of England starting from Lyme Regis eastwards in May 1813. |
