Fore limb bones of Hoplophoneus primaevus latidens Thorpe. U.S. National Museum. Washington, DC. Plate 29, in U.S.Geological Survey Professional paper 221-H. 1950
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The hydrogeologic framework was developed from a combination of the physiography and the predominant texture of surficial geologic units in the Mid-Atlantic Coastal Plain. It describes the primary natural physical factors that affect the flow and chemistry of shallow ground water and small streams in the Mid-Atlantic Coastal Plain. Seven hydrogeologic subregions were defined. Some of the subregions correspond directly to the physiographic...
Album caption and index card: Morphology of a crystal of colemanite, CaB3O4 (OH) 3.H2O, being studied with a two-circle optical goniometer by Joan R. Clark. The crystal is mounted on a goniometer head on the vertical circle at the left, the horizontal circle is at the bottom of the instrument, a light source is at the back, right, and the optical system is in the center of the picture. By rotating the crystal around the axis of either the vertical or the horizontal circle it is brought into position to reflect light from the crystal faces at given angles. The reflections can be observed through the optical system, their angular readings recorded, and hence the angles between various crystal faces can be measured....

Handwritten note on back of photo: Pick & Hammer Show. Whitmore's presentation of P&H's leather medal award to Ed Eckel - accepted in lieu of by Harry Ladd. 71415-13-9. Stamped on back of photo: The Geological Society of America, Washington D.C. 1971, Annual Meeting November 1-3.
These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Physiography for the Mid-Atlantic Coastal Plain was constructed by standardizing and extrapolating previous physiographic interpretations for areas within and adjacent to the region.

Ginkgo trees. Lafayette Park. Washington, D.C. 1916.
Treated effluent from wastewater treatment plants (WWTPs) contains contaminants not fully removed during the treatment process and that may pose environmental health risks when discharged to surface waters. This data release presents inputs for and results from a wastewater reuse model that used data compiled from several sources to calculate the following estimates for each non-tidal, non-coastline, initialized National Hydrography Dataset Version 2.1 (NHDPlus V2) stream segment in the Potomac River watershed: (1) accumulated wastewater as a percent of total streamflow (ACCWW%); and (2) predicted environmental concentrations (PECs, in micrograms per liter) of 69 municipal effluent-derived contaminants. ACCWW% values...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. Surficial geology for the Mid-Atlantic Coastal Plain was compiled and interpreted from available published and unpublished sources. Formation contacts were interpolated across unmapped areas and inconsistencies in nomenclature, interpretation, and scale were resolved to the extent possible. For more information, see U. S. Geological Survey Professional Paper 1680.
