Sedimentary rock paint

posted by Jason Kottke   May 23, 2011

There’s a rock at the main intersection of White Rock, New Mexico that’s often repainted, sometimes two or three times a day. My pal Mouser and a couple friends of his took a core sample of the rock to determine the paint thickness…turns out there was five and a half inches of paint on that rock. Here’s a composite photomicrograph of the paint layers.
