Open-File Report 2007–1002G
Data were collected and experiments were conducted from 2003 to 2006 by the U.S. Geological Survey, in cooperation with the Bureau of Land Management, to support research into understanding processes that liberate, disperse, and concentrate erosion byproducts in Mancos Shale landscapes. The study area was the Gunnison Gorge National Conservation Area near Montrose and Delta, Colorado. This report includes data collected from 24, small-plot, rainfall-runoff simulations, 6 hillslope-erosion monitoring plots, 20 hillslope-creep monitoring sites, and 3 precipitation gages. Small-plot rainfall-runoff simulations were performed on paired (undisturbed and disturbed) plots to examine the effect of off-highway vehicle use on runoff and erosion. These data were collected in conjunction with several other studies done by the U.S. Geological Survey in the Gunnison Gorge National Conservation Area. Data collected in companion studies are published in separate open-file reports.
