More than halfway around the world, more than half a lifetime ago, we had a wall calendar at home, one with a photograph for each month. Some of them are deeply etched in my memory—some that I could recognize like the Ruwanweliseya and Jethawanarama Stupas across the Basawakkulama Lake in Sri Lanka, and some that I couldn’t recognize like a line of beehive-shaped piles in a sun-soaked desertscape. Then awhile back, I was researching Death Valley National Park and stumbled across those beehive-shaped piles—the Wildrose Charcoal Kilns that are a remnant of California mining in the 1800s, and had endured a century of work and abandonment. When we saw them following a snowstorm, they looked far from the photo on the calendar, but were still as fascinating and impressive as ever. Here is to enduring memories.
