Franco Banfi is a professional underwater photographer, renowned for his spectacular images of marine wildlife, captured across every ocean on the planet. In 2010, Banfi, a Swiss national, dived into the Lago di Sassolo (Lake Sassolo) to reveal the hidden wonders of the ice mazes which form in the glacial lake at 6,560 feet (2,000 m) above sea level, in the European Alps.

Ice diving is highly technical, and is complicated when undertaken at altitude. Banfi has been diving for 35 years, and has “around 100 dives under the ice,” experience gained through his pursuit of the perfect image of rarely seen species. In 2005, Banfi chased Greenland sharks (Somniosus microcephalus) in the Arctic Circle, and leopard seals (Hydrurga leptonyx) in the Antarctic Ocean.

Banfi wound his way through the sub- and englacial pathways of the ice, in temperatures around 35.6-37.4°F (2-3°C). He remarked, “It can be dangerous if you don’t know the place and if you don’t have experience in an ice environment.” However, Banfi was raised in Cadro, Switzerland, and grew up diving Lago di Lugano (Lugano Lake).

Reflecting on the dangers of his dive at Sassolo, Banfi said “It gets quite dark depending on how much ice there is above your head at the surface – so in some places with thicker ice it gets dangerously dark.” He added, “Ice like this can collapse anytime,” as the exhaled bubbles alter the buoyancy of the overlaying ice.

According to the seasoned diver, his underwater model and dive partner Sabrina Belloni joined him on the journey through the icey labyrinth, but was hesitant, awaiting terrifying signs of an imminent failure of the thick ice. “You can usually hear the crack, but not always,” said Banfi. “If you hear this, it’s already too late.”
