It could be argued that the open areas of the caverns felt as much like a Disney creation as Space Mountain. There were no dangerous mazes, no precipitous heights, no tight squeezes. Still, it was a cave, and so Anna had passed on repeat trips. Given the inevitable nature of things, she would spend much of eternity underground; no sense rushing on down before the grim reaper called for her. Her love of bats might have overcome her fear of enclosed spaces, but if one waited, the splendid little creatures were good enough to come out and be enjoyed in less Stygian realms.

This December she had been sent to CACA from her home park in Mesa Verde, Colorado. Trained teams consisting of park rangers from all over the region responded to catastrophes that ranged from hurricanes to presidential visits. This time it was the injury of a caver.

Had the caver been hurt in Carlsbad Cavern, extrication would have been simple: pop her in a wheelchair, roll her down to the snack bar and onto the elevator. She'd have been home before her mother knew she was missing.

But this caver had been injured in Lechuguilla. The cave was on NPS lands near CACA's headquarters. Lechuguilla was closed to the general public for the protection of both the cave and the visitors. Nearly ninety miles of the cave had been explored but it would be many years before it was fully mapped. Lech was a monster man-eating cave, dangerous to get into and harder to get out of.

Two days into Lechuguilla, a member of the survey team had been hurt in an accident. Not surprisingly there'd been a contingent of experienced cavers at Carlsbad at the time, a small but dedicated group given to squeezing themselves into dark holes and living to write home about it.

Before Anna and her teammates had descended on the park, the cavers had begun doing what they did best: getting one of their own back. Procedures in place from the last, well-publicized rescue from Lechuguilla, in 1991, the NPS had mobilized in record time. Within four hours of the report, Anna had been on a plane to El Paso. By the time she reached Carlsbad more than two dozen others from the southwestern region had arrived.
