Literal GeoSign

Lytton, BC is home to the only geosign I know of that is actually a sign made of geology. The jellyroll is a geologic structure made by a submarine slump. This monstrous example was uncovered at a local gravel mine, where they thankfully called in a geologist to coo over it excitedly. The process of preserving it by carefully pulling off a grain-thick layer for the my department, and another layer for the town, is pretty intense and awesome — check it out if you’re ever at UBC for a conference.
