The map that changed the world (http://www.livescience.com/history/051031_first_map.html)

Just two centuries ago, the world lacked a single geologic map. The chronology of the planet's history was unknown and effectively invisible to people despite the evidence of rock layers at cliffs and canyons.

Theological maps of the world then depicted such biblical concepts as the Garden of Eden. Some people believed that mountains grew organically like trees.

The study of nature and rocks was a novelty. Thinkers in the early 1800s disagreed over the age of the Earth, with some standing by Bible-based estimates of 6,000 years old.

Then along came the map that changed the world.

I recently read a great book by the same name, if this sounds at all interesting to you I would urge you to get a copy (library or bookstore).

Book on Amazon (http://www.amazon.com/exec/obidos/tg/detail/-/0060931809/qid=1130782640/sr=8-1/ref=pd_bbs_1/103-7188877-3100623?v=glance&s=books&n=507846)

William Smith discovered, among other things, that outcrops many miles apart can actually be the same formation (same age, same rock, same fossils) and that it is possible to create maps that show this.
