Sunday's first hour guest, explorer Bonnie Crystal(1) reported on her discoveries and experiences during her expedition to a Peruvian cave. One unusual finding was that of Asian-style letters and pictographs on a cave wall that she speculated might indicate that Asian people visited the South American continent earlier than thought. She also described a rock carving that looked like a "grey alien."
Crystal, who will be continuing her Peruvian expeditions for another month, said that experiencing some of the caves was like going into a time machine of the past, due to their untouched nature. One passage she entered "was like walking into a geode [that was] like being inside a fabulous array of jewels," she added.
Crystal, pictured left, has sent us a series of photos(2) documenting her cave explorations in South America. You can also view a video clip(3) (requires Windows Media Player) which shows her hanging from a rope inside a cave.
