San Juan River (Goosenecks State Park, Utah, USA) 2

The Goosenecks of the San Juan River is the best example on Earth of entrenched meanders. Meandering streams have a highly sinuous path and occur on nearly flat, low-slope land surfaces. The topography in southern Utah is rugged and steep slopes are common. The presence of a meandering stream in a rugged landscape seems paradoxical. The current landscape in southern Utah formed by tectonic uplift of the Colorado Plateau during the Cenozoic. Pre-existing streams on relatively flat landscapes retained their channel courses as they eroded downward through the uplifting plateau.

 

The bedrock walls along the San Juan River are Honaker Trail Formation and Paradox Formation (both Pennsylvanian).

 

Locality: Goosenecks State Park, southern San Juan County, southeastern Utah, USA
