Soaring at speeds of up to 160 kilometres per hour, Belgium base-jumper Cedric Dumont has embarked on his latest conquest — taming the ‘Crack’ gorge in Switzerland’s beautiful Churfirsten Mountains.

During his descent, which last about two minutes, Dumont is repeatedly seen only metres from the rock face below — such a small margin of error making this one of the most monumental, but high-risk, base-jumps ever attempted.
