Caught between a rock and a hard place. Indeed. Norway offers a sandstone manifestation of this dilemma: Kjeragbolten, a boulder wedged in a mountain crevasse, hovers above an abyss some 3,300 feet deep (hello rock, hello hard place). A popular tourist destination due to its equipment-free accessibility, the site also lures BASE jumpers. Gulp. Geologists believe the boulder was deposited during the last glacial period, when the fjord flooded (meltwater had already formed and reformed the valley some 22 times before). Talk about change. I’m inspired slash daunted, which means it’s time to pack this rucksack (from the inventor of the modern messenger bag) and get momentum on my side.
