MonsterQuest: Season 3Throughout history there have been countless sightings of mysterious creatures, from Megladon, the father of the great white shark, to gators in the sewers, a result of the rising gator populations clashing with human encroachment, and on to the Snow Beast of the Colorado Rockies that is thought to be hunting the elk population while fleeing man.

Most of what we know of these creatures comes from campfire stories, blurry films and grainy photographs. Season 3 of MonsterQuest, brings science and technology to bear on these creatures of legend and seeks confirmation of their existence.
