On a Pueblo dig: Exploring enigma of 'lost' peoples

"Higher in the canyon I settled in a copse of half-lit junipers, took off my pack, and pulled out a down sleeping bag designed for nearly twenty below zero," explorer Craig Childs writes in "House of Rain: Tracking a Vanished Civilization Across the American Southwest." "It would be barely warm enough tonight."

Childs battled nature in a search for the truth behind the supposed disappearance of a real prehistoric Native American culture, the Anasazi -- ancient Pueblo peoples whose culture thrived between the 11th and 13th centuries in Chaco Canyon, modern-day New Mexico. He hiked countless miles under summer's oppressive desert sun, and braved subzero temperatures throughout isolated winter nights. Even during droughts the risk of a rare flash flood was always present, even if clean drinking water was not.

The link is a book review. Nothing in the review seems too bizarre. Childs apparently goes along with the more recent arguments on more violent Anasazi.
