Guadalupe Mountains National Park, Texas

If you tell a Texan that there are mountains in their state, they will laugh at you and say you're crazy! (I know this from first-hand experience). Quite to the contrary, the bottom of the Rocky Mountains find their home in the panhandle of Texas, and it is quite a sight. The park consisted mainly of a 250-million-year-old coral reef that was lifted some 8,000 feet into the air when the Rockies were being formed. It's a spectacular site with these amazing limestone formations, like none other we have seen.
