Glen Canyon Dam High Flow Experiment Time Lapse Videos


Time lapse movies of the Colorado River-Grand Canyon experiment run in March are posted online at the USGS site for Mile 3 and 45 in lower and upper Marble Canyon. They show the effects for 30 days after the flow was increased below Glen Canyon dam. What's striking is how quickly the sandbars and beaches are eroded away.
