What is this close-up picture? (WotsThat: tree bark texture)

Question

What object is shown in this zoomed-in close-up photo?

Accepted Answer

tree bark texture. Some trees like the sycamore and plane tree literally shed their outer bark in jigsaw-puzzle-shaped pieces to stay clean, revealing bright white or yellowish wood underneath that looks almost like camouflage. This self-shedding habit helps them survive in polluted urban environments where other trees would get suffocated by accumulated grime.
