The intriguing theory of a land bridge linking Siberia and Alaska during the Ice Ages-a path for such prehistoric giants as woolly mammoths, steppe bison, and saber-toothed cats-had been much debated since the idea was first proposed over 400 years ago. But proof of the land bridge (now called Beringia) eluded scientists until an inquiring geologist named Dave Hopkins set himself to the task of solving the mystery. The Last Giant of Beringia tells this fascinating scientific detective story through the life story of the eclectic Hopkins, who rewrote history, and in doing so earned his place as the last giant the land bridge would ever know.
