Summary:
- This article discusses the discovery of unusual wrinkle-like features on the surface of a rock formation in Utah, which are estimated to be around 180 million years old.
- The wrinkles are puzzling to geologists because they do not fit with the typical processes that create geological features over such a long timescale, suggesting there may be a previously unknown mechanism at play.
- The article highlights the importance of field observations and the potential for new discoveries that can challenge our understanding of Earth's history and the processes that shape its surface.
