44) Oklahoma - Tenkiller Lake:
The history of Tenkiller is intertwined with the history of the Cherokee. In 1829, the US Government declared this land "Cherokee Land," and nearby Tahlequah became the capital of the Cherokee Nation. Lake Tenkiller was named after the Cherokee family who provided the land to build the dam. It’s said the original Cherokee warrior was called "Tenkiller" because of the ten notches on his bow.

45) Kansas - Private Lake near Wichita:
We saw some very unusual Christmas tree-like spires that seemed to be held up by small bubbles. It was gas, probably some clam’s burp that pulled the algae mat upwards creating these strange "trees." Numerous bass and other small fish seemed surprised to see scuba divers. They were probably thinking "Hey, don’t you know you’re in Kansas!"

46) Texas - Abilene nuclear missile silo:
The scuba experience is enhanced by realizing where you’re diving. I couldn’t help realizing that when I was a ten year-old Connecticut kid, this silo contained an armed nuclear missile ready to launch World War III. I recalled the insanity of Mutually Assured Destruction (MAD), and how it could have ruined my scuba diving career.

47) New Mexico - The Blue Hole, Santa Rosa:
It was time to check out this blue hole, or "nature’s jewel," as the locals call it. I wasn’t expecting much. After all, this wasn't Florida - we were a thousand miles from the ocean. What kind of water could you get out here? Then I saw it. Like something out of the Garden of Eden, a magical pool sixty feet across appeared with crystal clear blue water. "Could this be real?" I wondered. It was.
