Sanders assisted John Phillips and Henry De la Beche with the geological mapping of SW England in 1839-40. He fell out with De la Beche over an expenses claim and vowed to complete the geological mapping of his home district before De la Beche’s Geological Survey. He compiled the base map at his own expense and carried out all the field work, completing two years before the Geological Survey. Rare.
