This week’s photo challenge asks: “What does silence look like? Show us your take in a photograph.” I do hope that those of you who haven’t had the privilege of visiting a desert can sense the silence. Like other deserts I’ve visited (and lived in), Joshua Tree National Park is quite still. No leaves to rustle in what little breeze there may be. No planes, trains, cars. No bird noises. Just stillness. The Joshua Trees above welcome you to their quiet land.
