Geomorphology and Campsite Data, Colorado River, Marble and Grand Canyon, Arizona

This ESRI geodatabase consists of 5 feature datsets with 23 individual polygon feature classes and two raster datasets. A master campsite polygon feature class represents the boundaries of campsites identified in the 1973, 1984, and 1991 campsite inventories of the Colorado River corridor in Grand Canyon, Arizona. The other polygon feature classes represent camp locations along the Colorado River corridor in Grand Canyon, Arizona during different survey periods using different surveying techniques. The raster datasets represent sub-aerial and sub-surface sandbar surfaces at 37 long term-monitoring sites between Lees Ferry and Diamond Creek, Arizona in Grand Canyon National Park, measured in September and October of 2002 and 2009 at sites where campsite areas were also surveyed and measured. These data are associated with the U.S. Geological Survey Report: Hadley, D.R., Grams, P.E., Kaplinski, M.A., Hazel, J.E., Jr., and Parnell, R.A., 2018, Geomorphology and vegetation change at Colorado River campsites, Marble and Grand Canyons, Arizona: U.S. Geological Survey Report 2017-5096, 64 p., https://doi.org/10.3133/sir20175096.
