     "text": "Since 1990, the Grand Canyon Monitoring and Research Center in cooperation with Northern Arizona University has been monitoring sandbars by topographic survey (http://www.gcmrc.gov/sandbar/). Beginning in 1998, campsite area has also been measured on a subset of the sandbar monitoring sites. Campsite areas are defined as areas that are flat (less than 8 degree slope), smooth (not rocky), and clear of dense vegetation. This monitoring has shown changes in campsite area caused by vegetation expansion and sandbar erosion/deposition."

     "text": "Sandbars have been used as campsites by river runners and hikers since the first expeditions to the region more than 100 years ago. Sandbar campsites continue to be an important part of the recreational experience for the more than 25,000 hikers and river runners that visit the Colorado River corridor each year. Because the Colorado River is dominated by bedrock cliffs and steep talus slopes, sandbars provide unique areas along the river that are flat, relatively free of vegetation, easily accessible by river runners, and able to withstand high usage with negligible impact."
