Vanished radio mast, hollow rust shell
All rust, no mast.
A lattice radio mast stands in a desert basin, but it is only the rust: thin, torn orange skins in the shape of every girder, with no steel inside. The corrosion outlived the thing it was corroding.
Field noteOxide can keep a girder’s shape after the steel goes, but flakes that thin should never hold a tower up.
