The plumber's guide to the Colorado Basin

  When John Wesley Powell rafted down the Colorado River, he was probably not thinking of plumbing. But that's the metaphor the Dinosaur Nature Association brings to life in a poster of the dams, reservoirs, and aqueducts that have transformed the rivers of the Colorado Basin. Based on Lester Doré's illustration from HCN's book, Western Water Made Simple, the map shows the rivers in the basin on one side and a series of pipes, funnels and holding tanks on the other. Proceeds from the $7.95 poster support the nonprofit association's educational programs, produced with Dinosaur National Monument and the National Park Service.
