Robert Young, associate professor of earth and environmental science and physical geography poses next to a pair of replica bear skulls that he recently acquired to be used in his ice age environmental class at the University of British Columbia’s Okanagan campus. The skull on the left is a replica of a Giant Short-Faced Bear which grew to 1,400 to 1,700 pounds and roamed from California to Alaska thousands of years ago. The skull on the right is of a Cave Bear which roamed Europe thousands of years ago.
