A team of researchers has finally solved the century-old mystery of why the Green River in Utah flows uphill. By analyzing the river's channel and surrounding land, they found that the river was once a gentle stream that flowed east but was later captured by a stream from the south. The land around the Uinta Mountains had shifted, causing the river to change course and flow uphill.
