Throughout history there have been countless sightings of mysterious creatures, from the dreaded Mothman, a giant winged monster spotted in the sky over West Virginia, to the elusive Sierra Sasquatch seen across the Pacific Northwest. Most of what we know of these creatures comes from campfire stories, blurry films and grainy photographs. Now in its fourth season, MonsterQuest brings science and technology together to bear on these creatures of legend and seeks new, reliable evidence of their existence. One part history, one part science and one part expedition, MonsterQuest discovers the truth in these sightings and the legendary creatures behind them.
