We’re going to the Great Lake’s deepest point – join us LIVE!
More than 55 km (34 miles) offshore and over 400 meters (1,300 feet) beneath the surface of Lake Superior lies “Superior Maximus” — the deepest point in the largest freshwater lake on Earth by surface area. No sunlight reaches this extreme environment, where pressure is more than 40 times greater than at the surface.
Forty-one years ago, scientists descended here in a submersible. Since then, the depths have remained virtually unexplored.
In June 2026, filmmakers and Fellows of the Royal Canadian Geographical Society Yvonne Drebert and Zach Melnick are returning to Superior Maximus using a cutting-edge Boxfish Robotics Luna ROV equipped with a fiber-optic tether and high-resolution imaging systems — documenting this hidden world in unprecedented detail for the upcoming documentary Hidden Below: The Great Lakes.
Audiences can experience the expedition’s most challenging moment LIVE: the first descent to the deepest point in the Great Lakes. Visit hiddenbelow.live for more details!
