Desert pavement (Deserts 🏜️)

A desert pavement, also called reg, serir, gibber, or saï is a desert surface covered with closely packed, interlocking angular or rounded rock fragments of pebble and cobble size. They typically top alluvial fans. Desert varnish collects on the exposed surface rocks over time. Geologists debate the mechanics of pavement formation and their age.

@planetaryecologist That is pretty cool. This is what the Panamint Valley typically looks like. Not as packed and this area gets flash floods as well (On a side note I typically spot in the same place so I snap that particular tin ever 1-2 years)

@planetaryecologist ehm, isn't it that the sand and finer grains between the pebbles are blown away, leaving only the larger pebbels? And varnishing them by the abrasion of the sandgrain loaded wind?
