The Desert's Perfect Polka Dots: Who Draws the Fairy Circles?

2026-07-01 · Enigmatic Places · 8 min read

Fly low over the grasslands at the edge of the Namib Desert and the ground looks stitched by hand. Millions of bare, reddish circles pepper a sea of golden grass, each ringed by a fringe of taller stalks, each held apart from its neighbours with almost mathematical regularity. From the air the effect resembles the hide of some vast, spotted animal. On the ground it is stranger still. Step inside a circle and the earth is simply, stubbornly bare, while the grass beyond the rim grows thick and tall. There is no fence, no rock, no visible reason for the line where life stops and the bald red disk begins.

The circles run from about two to fifteen metres across, and they are not fleeting. Researchers estimate that an individual circle can persist for decades, being born, maturing and fading over the span of a human life, only to have a new one open elsewhere in the field. The line at its edge is sharp, and it holds, year after year, through drought and flood alike.
