What Did the Continents Look Like Millions of Years Ago?

The paleo-tectonic maps of retired geologist Ronald Blakey are mesmerizing and impossible to forget once you’ve seen them. Catalogued on his website Colorado Plateau Geosystems, these maps show the world adrift, its landscapes breaking apart and reconnecting again in entirely new forms, where continents are as temporary as the island chains that regularly smash together to create them, on a timescale where even oceans that exist for tens of millions of years can disappear leaving only the subtlest of geological traces.
With a particular emphasis on North America and the U.S. southwest—where Blakey still lives, in Flagstaff, Arizona—these visually engaging reconstructions of the Earth’s distant past show how dynamic a planet we live on, and imply yet more, unrecognizable changes ahead.
