The Tracker's Diary: Bears of Katmai

The crew heads inland to a section of the river to observe the many different families as they fish.

After seeing a wolf in the distance and tracks on the shore, the crew head inland in search of more clues to the wolfs whereabouts.

Casey and his crew wander the tidal flats and interior of Katmai and find the bones of a humpback whale that washed ashore.
