Come to Montana and go up the Beartooth Highway, u go from around 6k to 13k+ in about 40min.
You're a little off. I believe the Beartooth pass is a little under 11K. I used to drive it about once a month (when it was open) It is a FANTASTIC drive.
There is no place over 13K in MT, Granite Peak (highest in the state) is 12,800.
