World Class Natural Wonders
Next to the land, the principal natural resource of the byway is water. While it can be hard to see this incredible resource while moving along the byway, below the miles of grass-stabilized sandy surface in this region lie hundreds of feet of gravel and coarse sand, forming one of the largest aquifers in North America.
Underground water from the High Plains Aquifer is an important natural occurrence that yields plentiful supplies of water all along the byway.
The Ogallala Aquifer, which is directly underneath the Sandhills Journey Scenic Byway region, underlies approximately 63,650 square miles or 83 percent of Nebraska! Generally, groundwater can be found from 1 to 500 feet in depth, but within parts of the byway region, saturated thickness of the aquifer is more 1000 feet deep.
