A few from Oklahoma.
1. The Glass (pronounce "Gloss") Mountains in NW Oklahoma. The name is said to be reflective of the selenite crystals in the bluffs but a more colorful local story is that the name was originally applied by an Englishman and the locals misunderstood his pronunciation of "glass".
2. Little Sahara State Park.
3. A creek in Roman Nose State Park. The land that is now the state park was given to the Cheyene chief Henry Roman Nose after the Indian wars. He lived there until his death in the early 20th century.
I hope you enjoy these. Oklahoma has more variety in the landscape than most people realize. Comments welcome.
