National Geographic: Bear Island: The majestic Alaskan brown bear is the largest predator in southeastern Alaska, but its ancient haunts are under siege. As modern worlds close in, the great bears world is shrinking and encounters between humans and bears are on the rise. Join researcher LaVern Beier as he uses cutting-edge technology to protect this extraordinary species. To observe on their own turf, without risking life and limb, LaVern attempts to deploy National Geographics Crittercam, until now used almost exclusively on marine animals. Vern and his colleagues are on the cusp of a revolution in terrestrial field science: the opportunity to vicariously walk with bears into the deepest comers of their habitats.
