I think this is a beautiful synthesis of the state of information today regarding human occupation of the higher latitudes (read: brrr chilly). I have never met Dr. Hoffecker but I was one of the last students of Dr. Roger Powers, with whom Hoffecker worked in Alaska in the Nenana Valley and elsewhere, in the search for early human occupation in Alaska. Coupled with the same author's book on the Eastern European record, it provides an excellent picture of an important aspect of the upward trajectory of humanity from ambitious primate to h. sap. technologicus. If I return to teaching I will definitely use this as a text where subject appropriate, and in my consulting work I will likely refer to it frequently as the newest and best compendium of information.
