serir
noun1
A desert of pebbles or larger stones.
- Immediately south of Tejerri, the most southern village of the Gatrun oasis, the sandy desert disappears, and great serirs, large fields covered by fine gravel, slowly lead up into a succession of broad valleys and ridges of an unsurpassed wildness.1909, Royal Geographical Society (Great Britain), The Geographical Journal, page 256:
