The first geological map of the United States was produced in 1809 by William Maclure. In 1807, Maclure began the self-imposed task of making a geological survey of the United States. Almost all the states of the Union were crossed and mapped by him, the Allegheny Mountains were crossed and recrossed about 50 times. The results of his unaided labors were presented to the American Philosophical Society in a memoir entitled Observations on the Geology of the United States Explanatory of a Geological Map, and published in the Transactions of the Society, together with the first geological map of the nation. . This predates William Smith's geological map of England by six years, although it was constructed using a different classification of rocks.<end_of_turn><eos>
