So photogenic that its nickname is ‘Kodak Gap,’ this steep-sided channel runs 11km between the mountains of Booth Island and the Peninsula. The passageway is quite deep – more than 140m for most of its length – and at just 1600m wide it’s only visible once you’re almost inside.
The channel was discovered by a German expedition in 1873–74, but wasn’t navigated until December 1898, when de Gerlache’s Belgica sailed through. In a decidedly odd choice, de Gerlache named it for Belgian adventurer Charles Lemaire, who explored the Congo. Ice sometimes blocks the way, so ships may be forced to retreat and sail around Booth Island. At the Lemaire’s northern end are two tall, rounded peaks at Cape Renard. The taller of the pair, at 747m, was summited by a German team in 1999.
