Abstract

The timing of formation of the Grand Canyon, USA, is vigorously debated. In one view, most of the canyon was carved by the Colorado River relatively recently, in the past 5–6 million years. Alternatively, the Grand Canyon could have been cut by precursor rivers in the same location and to within about 200m of its modern depth as early as 70–55 million years… (More)
