Sand

Michael Welland draws us into the world of sand - sand in grains, rocks, and vast and magnificent landscapes on which the wind plays haunting melodies. Packed with fascinating science, laced with tales of explorers, sand art, and the tribes of the desert, this work will appeal to all those intrigued by the nature of sand, and the beauty of deserts.

This book is all about sand - sand in individual grains, each one a little different; sand in piles; sand in shoals and dunes; the science of sand but also, shot through the book, sand and imagination - the art and the music of sand. Did you know that the Sand Mountain in Nevada emits a low C, while dunes in Chile sound an F, and those in Morocco a G#? For all its ubiquity, sand is an extraordinary substance. For scientists, it is important in many ways: it represents the crushed remains of past rock, and builds up into layers in lake and ocean beds, layers of sandstone from which we can extract the history of deep time; its erosion creates complex landscapes of mounds and dunes which move in characteristic ways; its grains are remarkable individually and in their behaviour together as a granular material. And to travellers, poets and artists, the deserts it forms are full of grandeur and pathos. Michael Welland is a geologist who has a passion for sand. He shows that truly, one can see a world, both in space and time, in a grain of sand.
