How the States Got Their Shapes

Look at a map of the USA, and every state tells a story. Oklahoma's panhandle tells a tale of slavery. Missouri's boot-heel hitch into Arkansas is the footprint of a real earthquake and one man's dream.

Texas and California are huge for a reason. There's a tale in West Virginia's unicorn horn.

State boundaries may look like a crazy jigsaw — random, or rigged, or arbitrarily straight and narrow. But there's a reason every time. And some wild stories out there.

This hour, On Point: We're having fun with history, and how the states got their shapes.Guests:
