Ribbons of color flowing down the Moreau

The Moreau River flows eastward across Northwest South Dakota, USA, across a previously glaciated terrain. Beginning in a North Fork and South Fork, it travels 320 km on its way to the Missouri River. The image is a high resolution topographic model created in Global Mapper using USGS LiDAR elevation data at a 1m resolution. The color ramp is designed to hi-light slight elevation changes by cycling every 10 meters.
