"In this narrative, William Ashworth tells the history of the Ogallala, from its formation after the retreat of the glaciers to its uncertain future. The most dramatic part of that history deals with efforts to exploit the hidden waters, starting with the primitive wells of long-vanished tribes, through the invention of the center-pivot sprinkler, and on to ever more sophisticated extraction technologies. This is an account of people as well as water, with many vignettes of those living in the shadow of the Ogallala's decline."--Jacket.
