"Why is there sand in deserts? Because windblown sand collects in every low place, and deserts are low, like beaches.  However far you live from the sea, however high your altitude, you will find sand in ditches, in roadside drains, and in cracks between rocks and sidewalks....clay particles clump and lie low; sand grains part and blow about...winds drop sand by weight, as one drops anything when it gets too heavy for one's strength.  Winds carry light stone dust--loess--far afield.  Wherever they drop it, it stays put only in a few places..."
