NOVA series tours Earth history, Aussie style

It’s the geologist’s refrain: rocks tell stories. Geologists don’t (usually) get excited about a chunk of sandstone just because it’s sandy. It’s the secrets it holds—secrets about a world in the past that we can never visit, even as we stand on its consequences.

“Australia’s First 4 Billion Years," a four-part series that begins April 10th on NOVA, recounts the tale of Earth’s history the right way—by letting the rocks tell it. And it does so without even leaving the land down under (save a short stop in New Zealand).

That’s not a limitation, it’s a strength. It allows the program to hone in on details that many won't have heard before, rather than providing a montage of interesting events around the world—an approach that usually yields only the most familiar ones. The program builds an appreciation for the landscape, too, by allowing you to more fully explore the rich history of a region. Besides, Australia’s geology lays bare an impressive amount of geologic time. You could do much worse as far as locations go.
