Carlsbad Caverns National Park, New Mexico

Bats!. millions of black little mammals drifting along the horizon and seeming to fuse into the hazy clouds of a New Mexico sunset! That was the spectacle which led Jim White, back at the turn of the century, to become interested in the colossal phenomenon designated by Act of Congress as Carlsbad Caverns National Park.

If you could ask him about it today, Jim's eyes would probably turn inward as he'd muse and remember. "I thought it was a volcano -- but then I'd never seen one. For that matter, I'd never seen bats fly. I had seen plenty of prairie whirlwinds during my life on the range, but this thing didn't move. It seemed to stay in one spot near the ground -- but the top kept spinning upward. I watched maybe a half-an-hour, and being about as curious as the next fellow, I started toward the place".
