Here’s a billiant subway-style map of US national parks, created by the Sierra Club.
Apart from being a pretty clever way to display national park locations, the map certainly draws attention to the fact that there are a lot of national parks in the US; perhaps a lot more than most people realize. Sure, everyone knows of the really famous ones such as Yellowstone, Yosemite, and Death Valley, but as you can see, there are plenty more national treasures to be discovered.
How many national parks stops have you made? When was the last time you left the city and went out into big nature?
