Rumors of Indians, mosquitos, and fierce weather created a 20,000 sq. mile deserted island in the sea of new settlers. “People who go in there never come back out.”
Then cattle discovered the place.
Today, the Sandhills looks much as it did before white man arrived, save for the occasional barbed wire fence and ranch sign, which bear many of the same names as the guys who followed their cows in here 140 years ago. Within, lie the top three cattle producing counties in the US.
Geologically, the Nebraska Sandhills leave much to speculate. Ask five experts how this sand got here and you’ll more than likely get 5 different answers (with the smartest experts skirting the question). Then there's the water. Not only do twenty-plus rivers and streams flow out of the area, but the Sandhills supply much of the water in the Ogallala aquifer, providing ground water to farms and families spanning Nebraska and beyond. And all this from a land that averages less than 20 inches annual rainfall.
In summary, the Sandhills of Nebraska is a fascinating destination. Be careful though, explore it too closely and you may get sucked into its inexplainable vortex... Speaking from experience.
