The Tracker's Diary: Bears of Katmai

In Katmai National Park, Alaska a massive population of coastal brown bears gather to eat salmon as they migrate back to the rivers and streams where they were born.

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

During a lull in bear and salmon activity, Casey and the crew decide to head inland in search of the spawning fish.

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

Casey and the crew go out in search of the family of the lost cub from the previous night. They hope that if they find them, the cub will have found them as well.

As the end of their expedition draws near, salmon and bear activity begins to decline, but that doesn’t mean that there aren’t some bears still lingering around the area.
