At Arches National Park, we scrambled over clusters of rock to walk along a sandstone fin with sheer sides, heart-stopping dropoffs and amazing views. I felt like I was queen of the world.
At its sister-park, Canyonlands, we looked out over miles of canyons, spires, and cliffs, cut by the Green and Colorado rivers. I felt small and insignificant.
And both parks, created from eroding and ever-changing rock forms, made me think about the impermanence of things that seem permanent.
