With no time to lose, I reached up above my head and grasped the last granite boulder separating me from the summit, but my heart instantly lurched as I heard the rock scrape against the stone beneath it and saw it begin to slide towards me! Desperately, I threw all my weight behind my hand, pushing back on the rock to attempt to stop its descent. My toes nearly lost their purchase on the hillside, but the boulder gained enough friction and ground to a tentative halt. One by one, I lifted my fingers delicately away, and I dared to release my inheld breath. That chunk of stone could have crushed me like a potato chip and brought an end to fun and games in Norway.
