This is a shapefile and coverage that outlines the area underlain by coals in the lower Blackhawk Formation, southern Wasatch Plateau coal assessment area. The polygons delimit the area within which resources were calculated and reported.

Final unioned polygon coverages and shapefiles used to calculate coal resources of the A through G coal zones, Danforth Hills coal field, northwestern Colorado. Danafing was used for the A coal zone; Danbfing was used for the B coal zone; etc. Polygons that make up the final unioned polygons include counties, 7.5' quadrangles, townships, surface and coal ownership, lease boundaries, overburden, and coal thickness categories. The final coverages were clipped to the resource areas for each coal zone, which are described in the metadata files for the *_bnd coverages.

Statistical analyses and maps representing mean, high, and low water-level conditions in the surface water and groundwater of Miami-Dade County were made by the U.S. Geological Survey, in cooperation with the Miami-Dade County Department of Regulatory and Economic Resources, to help inform decisions necessary for urban planning and development. Sixteen maps were created that show contours of (1) the mean of daily water levels at each site during October and May for the 2000-2009 water years; (2) the 25th, 50th, and 75th percentiles of the daily water levels at each site during October and May and for all months during 2000-2009; and (3) the differences between mean October and May water levels, as well as the differences...

This part of DS 781 presents data for the bathymetric contours for several seafloor maps of the Offshore Scott Creek map area, California. The vector data file is included in "Contours_OffshoreScottCreek.zip", which is accessible from https://doi.org/10.5066/F7CJ8BJW. These data accompany the pamphlet and map sheets of Cochrane, G.R., Dartnell, P., Johnson, S.Y., Greene, H.G., Erdey, M.D., Dieter, B.E., Golden, N.E., Endris, C.A., Hartwell, S.R., Kvitek, R.G., Davenport, C.W., Watt, J.T., Krigsman, L.M., Ritchie, A.C., Sliter, R.W., Finlayson, D.P., and Maier, K.L.

This archive contains the logistic mapping vulnerability output rasters at the conceptual well locations. Data are provided in rasters containing the estimated probabilities of nitrate concentrations greater than 2 milligrams per liter at hypothetical 150-foot-deep and 300-foot-deep wells.

The Clear Lake herd contains migrants, but this herd does not migrate between traditional summer and winter seasonal ranges. Instead, much of the herd displays a nomadic tendency, slowly migrating north, east, or south for the summer using various high use areas as they move. Therefore, annual ranges were modeled using year-round data to demarcate high use areas in lieu of modeling specific winter ranges. The areas adjacent to Clear Lake Reservoir were heavily used during winter by many of the collared animals. A few collared individuals persisted west of State Route 139 year-round, seemingly separated from the rest of the herd due to this highway barrier. However, some pronghorn cross this road near Cornell and...

The Mendocino mule deer herd complex is comprised of three overlapping black-tailed deer (Odocoileus hemionus columbianus) administrative herds, including Mendocino, Clear Lake, and Alder Springs. Mendocino black-tailed deer exhibit variable movement patterns and strategies, including traditional seasonal migrants, full-time residents, and multi-range migrants. Migrants move between seasonal ranges from a multitude of lower elevation areas within the North Coast Range in winter to higher elevation summer ranges (fig. XXX). Local biologists predict high-use winter ranges throughout both foothill slopes and valley bottoms. Female deer of the Mendocino herd complex exhibit both short-term (seasonal/annual) and long-term...

The winter ranges of the Northside mule deer herd can be broadly separated into northern and southern subgroups. The majority of the southern subgroup winters at low elevations near the John Day River in areas dominated by big sagebrush communities, Columbia Basin grasslands, and western juniper. The northern subgroup is more spatially dispersed, wintering by Cottonwood Creek, the North Fork John Day River, and the Middle Fork John Day River in ranges containing more conifer forest than those of the southern subgroup. Both subgroups summer in the same general area, migrating either northeast or southeast to reach ranges featuring mixed-conifer, Picea spp. (spruce), Ponderosa pine, and western juniper forests with...

The Klamath Basin mule deer herd contains an estimated 10,775 deer and features a mix of resident and migratory animals. Most winter ranges are adjacent to the California border near Bly and Lost River, California, in areas featuring western juniper, low shrublands, and early shrub-tree habitat. In spring, these mule deer either migrate northwest to regional national forest lands or northeast past South Fork Sprague River. Summer ranges contain ponderosa pine, mixed-conifer, and early shrub-tree habitat along with alfalfa and other agricultural crops. Notably, one mule deer migrated southeast into California near Goose Lake in May 2019 and spent a year near Deadhorse Reservoir before returning to Oregon in November...

With 204 GPS-collared mule deer, the Beulah-Malheur herd is one of the most extensively recorded mule deer herds in Oregon. Mule deer primarily winter along the Malheur River and the Stinkingwater Mountains, with some as far south as the Owyhee River. Winter ranges are covered by Artemisia tridentata (big sagebrush), grassland, and encroaching Juniperus occidentalis (western juniper). Although spatially dispersed, much of the Beulah-Malheur herd collectively migrates northwest to reach summer ranges across the upper elevations of the Malheur National Forest, Pedro Mountain, and Cottonwood Mountain. Primary summer range vegetation includes A. t. vaseyana (mountain big sagebrush), Pinus ponderosa (ponderosa pine),...

The Lassen herd winters in lower elevations in the Secret Valley, Bull Flat, and the Five Springs Wilderness Study Area north of the Skedaddle Mountains and east of Shaffer Mountain, as well as in the Dry Valley Rim Wilderness Study Area. Summer ranges are spread out, with some individuals migrating north to the Madeline Plains and others heading west to Willow Creek Valley, Grasshopper Valley, and Eagle Lake (fig. XXX). An unknown portion of the herd are better characterized as residents. The primary threat to pronghorn in the Lassen herd is the conversion of perennial shrublands to exotic annual grasslands following wildfires. The 2012 Rush Fire burned 271,911 acres in Lassen County within the boundary of the...

The Area 17-Toiyabe mule deer herd inhabits the Shoshone Mountains and Toiyabe Range, which run north to south in central Nevada (fig. 11). Mule deer from the Shoshone Mountains and Toiyabe Range are characterized by short distance migrations from high elevations above 7,874 ft (2,400 m), down to 5,577 ft (1,700 m). Since the 1920s, the lower elevation slopes east of Toiyabe Dome, between Wisconsin Creek and Broad Creek and locally known as Toiyabe bench, have been documented by the Nevada Department of Wildlife as crucial mule deer winter range. Because of the value of this habitat for mule deer, the BLM closed the area to domestic livestock grazing in 1983 (Nevada Department of Wildlife, 1985). In 2018, in collaboration...

Macroclimatic drivers, such as temperature and rainfall regimes, greatly influence ecosystem structure and function in tidal saline wetlands. Understanding the ecological influence of macroclimatic drivers is important because it provides a foundation for anticipating the effects of climate change. Tidal saline wetlands include mangrove forests, salt marshes, and salt flats, which occupy similar geomorphic settings but different climatic regimes. However, most global- or regional-scale analyses have treated these wetlands as independent systems. Here we used climate and literature-derived ecological data from all three systems, collected across targeted regional-scale macroclimatic gradients, to test hypotheses...

Landforms along the Pacific, Gulf of Mexico, and Atlantic coastlines for the conterminous United States are attributed with the relative vulnerability of horizontal erosion due to sea-level rise to characterize coastal zone stability. The position and extent of landforms are geospatially indexed as line-events where these coastal zone features are intersected by the linear-referenced 2013 - 2014 U.S. Geological Survey National Hydrography Dataset Coastline, which corresponds to the National Oceanic and Atmospheric Administration (NOAA) 2013 - 2014 mean high water level datum delineated in intertidal zones open to oceans, behind barrier coasts in bays, lagoons, and estuaries, and sometimes where tidal currents reach...
