An apron of sediment slopes out from the mountain, and they call it bajada. Sometimes a solitary rock pokes up through bajada, and they call it inselberg. Isolated mountain ranges, much larger than inselbergs, rise high above like ships on a desert sea. Sediment between them is often eight thousand feet deep. They have drilled many holes for water in this arid land to determine this. When I have a better feel for it, I’ll deal with the strange theory of how the land stretched, cracked, and became the basin-and-range physiographic province. For now, I am falling in love with arid desert and rocky crags, with plants and animals that make do with little water. Bear with me a few days and maybe I’ll get practical.
