This USGS Data Release represents geospatial and tabular data for the Denali Sampling Project. The data release was produced in compliance with the new 'open data' requirements as a way to make the scientific products associated with USGS research efforts and publications available to the public. The dataset consists of 4 separate items: 1. Sample Site Locations (Vector GIS dataset) 2. Sample Transects (Vector GIS dataset) 3. Final Index Score Output (Raster GIS dataset) 4. Sample Site Recordings - Finalized (Tabular dataset) These data support the following publication: Ignizio, D.A., 2015, Sample associated publication: U.S. Geological Survey Open-File Report 2016–xxxx, xx p., http://dx.doi.org/10.3133/ofr2015xxxx.

The National Science Foundation Ice Core Facility (NSF-ICF) - formerly the U.S. National Ice Core Laboratory (NICL) - is a facility for storing, curating, and studying meteoric ice cores recovered from glaciated regions of the world. NSF-ICF provides scientists with the capability to conduct examinations and measurements on ice cores, and it preserves the integrity of these ice cores in a long-term repository for current and future investigations.
The U.S. Geological Survey Denver Library maintains a collection of more than 400,000 photographs taken during geologic studies of the United States and its territories from 1868 to the present. These images provide a visual history of the discovery, development, and sciences of the United States and its Geological Survey. Some photographs have been used in USGS publications, but most have never been published. Currently, this website represents less than 10 percent of the Library's images with approximately 38,000 photographs on-line. Visit http://library.usgs.gov/photo/#/.
