We strapped on the crampons, swung the ice axes, ambled up Falljokull, the lava dirt outlet glacier of the mighty Vatnajökull glacier and looked deep into the valley of the mountain’s throat, its tiny meadow-like green patch that would make for difficult golf, the slopes in the far background that seemed almost Shangri-la, with a kind of mist that hung over them in the on an off sprinkle of rain. It was a contrast in earthtones, so I snapped it. Think I’m happy. “The glacier melts are always cycling forward and back,” said our UK glacier guide, “but in the past 5 years since I’ve been leading these hikes, they’re receding much much faster than any of us have ever seen before.” He paused, nimbly avoiding the hot stone topic of why. “It’s kind of sad, really.” You have to be here, in Iceland, in the Himalayas, in Tanzania–anywhere outside–and be surrounded on all sides by this kind of landscape to feel dread at the possibility that it might slip away in ours or our children’s lifetime.
