Went to the Carlsbad Caverns today. Lot of fun but if you have any mobility issues, take the elevator down. They said it was about a mile walk down to the main room and would take 45 mins to an hour. It took us about an hour and a half. In the group we had people with knee issues, hip issues, and ankle issues but not enough for aids on normal day usage.
Heading in

Some interesting formations (blob with no name, the chandelier, Swiss cheese or bone structure, and whale's mouth in that order)
