I have visited White Sands National Monument many times, and the place never fails to inspire me. My most recent visit a few days ago included camping overnight. The sun set behind the San Andres Mountains, and after an hour or so of darkness a nearly full moon rose, so I walked for a while among the moonlit dunes.
Next morning, I crawled out of a frost-covered tent, and wandered in the predawn light, looking for lessons to be found in colored clouds and rippled sand.
After a few drops of rain from a cloud that had to have its last word, the sun began warming the air, and by midday I was far into the dunes, marveling as I always do at the the patterns of light and shadow that last most of the day at this time of year when the sun remains far below the zenith.
