In this book, Michael Collins . . . demonstrates why he is considered one of the leading researchers in the field of lithic analysis. The work offers a masterful review and synthesis of Clovis blade technology with lucid prose and lavish illustrations. . . . I recommend this book for all professional and avocational archaeologists interested in Paleoindian occupations of the New World. (Illinois Archaeology) This book makes an important contribution to a newly revived debate on the significance of the Clovis phenomenon and the timing and migration routes of the peopling of the New World more generally.
