Summary
The viewpoints were first photographed by Stanton in 1889, and then re-photographed in about 1991, 2010 and sometimes other years. This set of photos focuses on change in riparian vegetation and partially overlaps a larger set of Stanton viewpoints re-photographed by Webb and others and available at http://wwwpaztcn.wr.usgs.gov/fscc/stanton-repeat-photography/index.php. The file of descriptive information gives viewpoint stake number, name, and river mile, and documents occurrence of the exotic shrub Tamarix ramosissima, changes in cover of native and invasive woody riparian vegetation, occurrence of Diorhabda spp., the beetle introduced to control Tamarix, reductions in cover of native Prosopis glandulosa, changes in cover of vegetation [...]

The original set of photos was collected by Robert Brewster Stanton to document a planned railroad line from Grand Junction, Colorado to San Diego, California. The railroad line was never constructed but the photos document conditions in the Grand Canyon prior to regulation of the Colorado River. In order to document changes in the Grand Canyon, the viewpoints were re-photographed by Robert H. Webb and others around 1991 and 2010 and other dates. The dataset described in this metadata is a subset of this repeat photo collection consisting of viewpoints documenting change in riparian vegetation. Those changes are documented in the attached file of descriptive information and discussed by Scott et al., 2018.
