Pawhuska  is in the Green Country region of Oklahoma.
- Tallgrass Prairie National Preserve. Tallgrass is North America's largest remaining tract of tallgrass prairie ecosystem. What once covered much of the US and Central Canada, remains here to be seen in its most pristine condition in Oklahoma. Keep an eye out for the buffalo herds here as they are one of the nation's largest, and be warned, buffalo can sometimes charge unprovoked. So be sure to keep your distance, especially in the spring when there are lots of buffalo calves around. edit
