I'll end with my favorite experience of the summer. We drove about an hour and a half from the station to the Eureka Sand Dunes in Death Valley National Park, the last fifteen miles on an infrequented washboard gravel road. The dunes are enormous. We hiked up and through them for twenty minutes until we found a flat spot to hang out. Then we all got naked and rolled and jumped and slid down the steep sides of the hundred foot sand mountains. We played by starlight until midnight when a yellow moon rose to light the rippled dunes and give us long moonshadows. I had been learning the summer constellations and was rewarded by the stars' incredible showing. After working sand into every crevice and under every hair of our bodies for about five hours, we fell asleep. We awoke a few hours later, before sunrise, and drove home to avoid the heat that makes it Death Valley. Thanks to all you interns for a great summer! ¶
