Entrenched meanders. (A) Entrenched meander development requires geologic uplift. (B) The San Juan River in Utah has superb examples of entrenched meanders. These meanders formed long ago on a flat floodplain and were preserved as they cut through sedimentary rocks. This photo was taken at Goosenecks State Park in Utah, whose name refers to the similarity between the meanders and the curve of a goose’s neck.(B. © Wild Horizon/UIG/Getty Images)
