This is an excellent collaboration between a writer and photographer. Mark Klett's photographs augment & somehow "complete" the text in a way that was a bit surprising. The short stories compiled have much to say about the limits and dangers of border walls; prescient for 1994, but downright essential in 2017. But it has more to offer than that.
Growing up on the edge of desert, the stories and photographs are familiar and yet revelatory, driving me to think about the southwest and life in general in different ways. Wendell Berry has asserted that in order to accelerate growth, one also has to accelerate rot; when things don't rot, they don't enrich the soil for new things to grow. In the arid desert, things rot incredibly slowly, if at all. Sometimes, they just desiccate.
But there is life there; in Nabhan's closing story he suggests a parallel between the sounds of the Sonoran desert with the the Australian outback. There's a drone in both places that simply resonates in our bones, a bit like the sound of the didgeridoo. Anyone who has lived there for very long, feels it in their bones.
