The rain on the Darb al-Arba'[a]in stays mainly on the plain

The quiet of the desert is something wonderful, you never hear a sound. The camel’s cushioned foot makes no noise and the air is perfectly pure; no dew falls.

-Gordon, Letter written between Berber and Dongola, October 28, 1877

I heard no loud stomping or scuffing in that herd of 150 head when moving fast at night, but yes quite a bit of susurrating through the stretches of soft sand, 600 feet kicking up millions of loose grains that gently fell back to earth like rain.
