About The Cover

Quartz spear point (6.4 centimeters long, museum catalog number 1273) from the Tapajós River. Excavations in a painted cave at Monte Alegre, Brazil, at the confluence of the Tapajós and Amazon rivers uncovered stone tools, pigment, and food remains from a late Ice Age culture. These early foragers, distinct from the Clovis and Folsom cultures of North America, penetrated the equatorial lowlands of South America. See 373 and the related News story on 346. [Photo: R.
