Calfifornia condor occurrence data, downloaded from USGS BISON. The USGS Biodiversity Information Serving Our Nation (BISON) project is an online mapping information system consisting of a large collection of species occurrence datasets (e.g., plants and animals) found in the United States, with relevant geospatial layers. Species occurrences are records of organisms at a particular time and location that are often collected as part of biological field studies and taxonomic collections. These data serve as a foundation for biodiversity and conservation research. BISON supports several data interchange formats to enable developers to write custom applications (http://bison.usgs.ornl.gov/services.html). The BISON...

Specimen of moderately rich oil shale showing fine laminations and the characteristic loop bedding. The zone a little below the center is most typical and represents the edges of polygons formed by sun cracks. From east fork of Parachute Creek T.5 S., R. 95 W. Garfield County, Colorado. 1924. Plate 17-B in U.S. Geological Survey. Professional paper 168. 1931.
Photomicrograph showing detail of the varves in the rich oil shale specimen in Bradley photo 321; the organic laminae indicated by marks are themselves finely laminated. The mineral laminae contain considerable organic matter, but they are readily distinguished by their coarser grain and greater thickness. Enlarged 320 diameters. Garfield County, Colorado. 1927. Plate14-A in U.S. Geological Survey. Professional paper 158. 1930.

Photomicrograph of a thin section of specimen from an analcite crystal bed, showing the idiomorphism of crystals and the abundance of dust like inclusions; the jet-black pyrite and the clear gray areas between the crystals are holes in the section. From a bed about 750 feet above the base of the Green River formation in the canyon of the White River, sec. 27, T. 9S. R.25 E., enlarged 36 diameters. Uintah County, Utah. September 14, 1925.

Small area of the polished specimen in Bradley 245; this shows a part of the oolitic sandstone which contains fragments of micro crystalline calcite with ferruginous oolite grains suspended in the positions in which they formed; fragments of algal limestone consisting almost wholly of Chlorellopsis and an unusually large oolite grains that show the wide banding characteristic of all the oolites in this bed. Enlarged 5 diameters. Specimen is from the basal part of an algae reef on the north side of White River, in the SW 1/4 sec. 30, T. 1 N., R. 95 W. Rio Blanco County, Colorado.
