小麦与地下水 · WHEAT AND WATER
The Dry Plain With a Hidden Sea — United States · Great Plains and High Plains Aquifer
高平原含水层横跨美国 8 个州，面积约 17.4 万平方英里。它把半干旱平原推向大型农业区，但水在地下，有限且补给不均。
地表写着草与风；井口写着玉米、牛群和圆形喷灌田。这里的现代定居，是与一份从空中看不见的地下资源签下的契约。
The High Plains aquifer underlies about 174,000 square miles across eight U.S. states. It helped turn semi-arid plains into a major agricultural region, but the water was underground, finite and unevenly replenished.
The surface says grass and wind; the wells say corn, cattle and center-pivot circles. Modern settlement here is a pact with a buried resource the map cannot see from above.
