Album caption and index card: Reverse fault in southern saddle of The Loop, looking northwest from boat in river. Apparent angle of dip is 12° below horizontal. Rocks at left, above fault plane, have been shoved about 10 feet past and over those on right. Curving of dark bed near middle of fault plane is called "drag." Rocks are unnamed upper member of Hermosa Formation. Canyonlands National Park. San Juan County, Utah. n.d. Note: Published as figure 75 in U.S. Geological Survey. Bulletin 1327. 1974.

This dataset represents the variety (count of unique classes within 0.5 ha) of vegetation communities, river channel and bare areas (often sand bars) mapped along the Colorado River bottomland from the Colorado state line (San Juan and Grand Counties, Utah) to the southern Canyonlands NP boundary, as of September 2010. Traditional image interpretation cues were used to develop the polygons, such as shape, size, pattern, tone, texture, color, and shadow, from high resolution, true color, aerial imagery (0.3m resolution), acquired for the project. Additional, public available aerial photos (NAIP, 2011) were used to cross-reference cover classes. As with any digital layer, this layer is a representation of what is...
Anthropogenic activity is causing dramatic changes in the nitrogen (N) cycle in many ecosystems. Most research has focused on the increase in N input caused by atmospheric deposition and invasion of N-fixing species, and on their effects on resource availability and species composition. However, in contrast to many ecosystems experiencing large increases in N input, many arid ecosystems are experiencing loss of nutrients due to land-use change. An important component of many arid ecosystems on a worldwide basis is the microbiotic crust, a biological soil crust composed of lichens, cyanobacteria, mosses, and algae. Nitrogen fixation by lichens and cyanobacteria comprising the crust is the primary source of N input...
During January-March of 1990 a study was conducted to determine the sources of sulfur oxides present at Canyonlands and Green River, Utah. Samples were collected at these two receptor sites and at several sites intended to characterize the chemical composition of air masses reaching the receptor sites from various geographical regions. The results of the sampling program have been given in the first paper in a series of three papers. In this paper, the concentrations of spherical aluminosilicate (SAS) particles, total fluoride, and particulate selenium, arsenic and lead are combined with meteorological data to obtain source fingerprints for the ratios of these species to SOx from the various regional sources that...

This collection of maps shows fluvial geomorphic features of the Colorado River bottomland including river channel boundaries at high flow (31,300 cubic ft/sec on 06/28/2011 at the Cisco gage) and at lower flow (3,410 cubic ft/sec on 09/06/2010 at the Cisco gage). Also shown is the bottomland boundary delineating the currently active fluvial surface; the bottomland is subdivided by both reaches and bottomland kilometers for reference. Centerlines for the bottomland and 2010 river channel are included, also.

This set of maps shows relative habitat quality for species that prefer open areas. Component layers (herbacoeus areas, distance to high water) are included, as are associated layers of channel boundaries, reaches, and bottomland kilometers.

These data are annual aeolian dust deposition calculations from vertical deposition at seven locations near the vicinity of Moab, Utah covering the period from 1999 to 2020. Data were collected by the U.S. Geological Survey Geosciences and Environmental Change Science Center (Denver, Colorado) and Southwest Biological Science Center (Moab, Utah) to "monitor sediment characteristics at sites selected to illuminate the relations between dust sources, present climate, and land use patterns" (Reheis 2003). The sites selected represent various land uses and land ownership including private land, multiple-use public lands, and restricted use National Parks. From 1999-2013 samples were sent to the Geosciences and Environmental...

These data consist of rectified aerial photographs, measurements of active channel width, measurements of river and floodplain bathymetry and topography, and ancillary data. These data are specific to the corridor of the Colorado River in Canyonlands National Park between Potash, Utah and the confluence of the Green and Colorado Rivers near Spanish Bottom, Utah. The time period for these data are 1940 to 2018. The shapefile data are measurements of features of the active river channel and floodplains of the Colorado River. The raster data are aerial images and digital elevation models (DEMs) for segments of the Colorado River in Canyonlands National Park, Utah. The aerial images depict the river channel and adjacent...
