Turns out we might keep our own little mental map inside our heads. That's no surprise. But researchers did not expect to find that our mental maps are oriented north like a printed or digital map.

In L.A. we have the Wilshire Boulevard skyline and the mountains to the north to orient on (or, if you're in the Valley, the mountains on all sides.) More from The Atlantic Cities.
