**Bird’s Foot Delta — Mississippi River** This model represents the Bird’s Foot Delta of the Mississippi River in southeastern Louisiana, USA. The delta is characterized by long, narrow distributary channels extending into the Gulf of Mexico, forming a shape that resembles a bird’s foot. The landscape forms as river sediments are transported downstream and deposited where the river meets the ocean, gradually building new land over time. The terrain model was generated from a 1-meter resolution Digital Elevation Model (DEM) obtained from the United States Geological Survey (USGS) 3D Elevation Program (3DEP) and distributed by OpenTopography. **Data Source:** United States Geological Survey (2021).
