Can you distinguish a bayou from a bay? A gulch from a canyon? Do you know the difference between a hill from a foothill? Geographical terminology is very specific! We may be able to easily define what a peninsula is, but what exactly is an isthmus? I recently encountered this very cool poster at the American Geological Society library on the UW-Milwaukee campus. I marveled at how well it visually defines a ton of geography terms. The magic of maps…one quick look can communicate volumes of information!
