Geological map
Special Collections
William Smith’s ‘A delineation of the strata of England and Wales, with part of Scotland’, published on 1st August 1815, is regarded as the first national geological map. A detail of the Bristol region is illustrated. The author was of humble origins and trained as a surveyor. Observations made in Somerset collieries led him to hypothesise about geological strata. Cutting local canals allowed him to test his ideas. The map is part of the nationally important geological library bequeathed to the University by Joan M. Eyles.
