Central Arabia — original illustration of Central Arabia

This scene is an original illustration set in Central Arabia. It lies in the subtropics, where the climate is hot desert — evaporation far outruns rainfall.

A string of camels walks along a dune crest, each with a single hump and a short sleek coat. Rippled red-gold sand runs to the horizon with sharp crest lines, and the late afternoon sun throws long shadows down the slip faces.

Why does a hot-desert camel have only one hump?

One hump and a short coat is the hot-desert build: the hump is a fat store that keeps insulation off the rest of the body so heat can escape. Sand seas this extensive need both a vast sediment supply and long-term wind to sort it. Travelling the crest rather than the trough is the practical route — firmer footing and a sightline.
