In a cave deep beneath the French Alps, German wire walker Lukas Irmler this summer led a team of French cavers and slackliners to an otherworldly site around 500 yards underground. Slacklining, the sport of balancing on an elastic wire, is more commonly practiced above ground—often at high altitudes, where it’s called highlining. The practitioners of the spelunking variant are calling it “deeplining.” The expedition was sponsored by caving and alpine equipment maker Petzl.
