It is, as someone told a National Geographic reporter in 1987, the place “where boots go to die.” During the last ice age it experienced what geologists call a periglacial climate—a zone at the edge of an ice sheet characterized by frequent freeze—thaw cycles that fractured the rock. The result is mile upon mile of jagged, oddly angled slabs of stone strewn about in wobbly piles known to science as felsenmeer (literally, “sea of rocks”). These require constant attentiveness if you are not to twist an ankle or sprawl on your face—not a pleasant experience with fifty pounds of momentum on your back.
