Here’s a tidbit for downtown Des Moines livers who have come to town by the prospect of a good job and that special vibe that makes the city so, well, special: 90 million years ago you could have enjoyed the view from your rooftop patio of a massive inland ocean that stretched from the suburbs to Denver. A new website provides a view of the lay of the landscape in Central Iowa or other points on the globe over the last 750 million years. Plug in your current address, and a blinking dot will show where your apartment was situated at, say, the time the first modern mammals, birds and insects emerged. The website is called Ancient Earth, where you’ll find a globe — yes, you can spin the globe — and menus that let you travel through time, watch the continents separate, and see land masses emerge. Read about the site and its creators at Fast Company.
