"In the Tapir Mountain Nature Reserve of Western Belize, late in 1989, Dr. Thomas Miller jumped into a tributary of the Roaring River and swam inside an unnamed cave’s vine-covered mouth. The American geologist wasn’t in pursuit of a lost Maya relic; he was there to study geomorphology: the formation of caves. What he found, however, led him to contact Dr. Jaime Awe, director of the Belize Institute of Archaeology, who recorded his findings in 1992. The cave’s twisting river, in places neck deep, wove underground to an elevated cavern filled with the skeletal remains of 16 human sacrifices, ranging from infants to mid-40-year-olds. And, in an upper, farther recess of the cave, a slender skeleton lay calcified to the cave floor amidst bat guano and predatory spiders."
