Coastline of the land of monuments… tiny monuments. Each of them would fit easily inside a single human cell. They’re formed out of semiconductor, and are the result of what we call micromasking: tiny bits of debris landed on the semiconductor before the etching step, and protected the semiconductor underneath it from being etched. The black “water” is actually glass, which looks dark and opaque under an electron microscope. The glass is probably the source of the micromasking debris, as well, microscopic fragments that got scattered when the glass broke nearby.
