Grinnell and Sperry Glaciers, Glacier National Park, Montana: A record of vanishing ice
Arthur Johnson
1980, Professional Paper 1180
Grinnell and Sperry Glaciers, in Glacier National Park, Mont., have both shrunk considerably since their discovery in 1887 and 1895, respectively. This shrinkage, a reflection of climatic conditions, is evident when photographs taken at the time of discovery are compared with later photographs. Annual precipitation and terminus-recession measurements, together with...
Chemical character of water in the Red River alluvial aquifer, Louisiana
M.S. Whitfield
1980, Open-File Report 80-1018
The Red River alluvial aquifer of Louisiana underlies approximately 2,000 square miles in the Red River Valley of Louisiana. The aquifer is Pleistocene in age and consists of clay, silt, sand, and gravel deposited by the Red River. Sand and gravel constitute the lower two-thirds of the deposit, the most...
Preliminary bathymetry of McCarty Fiord and Neoglacial changes of McCarty Glacier, Alaska
Austin Post
1980, Open-File Report 80-424
Preliminary bathymetry (at 1:20,000 scale) and other scientific studies of McCarty Fiord, Alaska, Conducted by the Research Vessel Growler in 1978, showed this 15 mile-long waterway to be a narrow, deeply scoured basin enclosed by a terminal-moraine shoal. This valley was formerly filled by McCarty Glacier, which began a drastic...
Hydrogeology of the Seldovia area, Alaska
Gordon L. Nelson, Wesley R. Danskin
1980, Open-File Report 80-952
Surficial materials in the Seldovia area, Alaska, are mapped as glacial drift over sedimentary bedrock, glacial drift over igneous and metamorphic bedrock, valley-bottom, alluvium, alluvial fan deposits, beach and intertidal deposits, and peat. Unconsolidated materials are generally less than 10 feet thick except in well-drained glacial deposits along the Seldovia-Jakolof...
Hydrologic monitoring program in Eldridge-Wilde and East Lake Road well-field areas, Pinellas and Hillsborough counties, Florida, 1978
L. R. Mills
1980, Open-File Report 80-1195
This report describes the observation-well network in Eldridge-Wilde and East Lake Road well-field areas, Pinellas and Hillsborough Counties, Florida. Data obtained in 1978 from the network in and adjacent to the two well fields, as well as rainfall and pumpage records, are presented. The Southwest Florida Water Management District has...
Ground-water models for water resources planning
John E. Moore
1980, Open-File Report 80-581
In the past decade hydrologists have emphasized the development of computer-based mathematical models to aid in the understanding of flow, the transport of solutes, transport of heat, and deformation in the groundwater system. These models have been used to provide information and predictions for water managers. Too frequently, groundwater was...
Surficial geology of part of Sandy Creek quadrangle, Oswego County, New York
Todd S. Miller
1980, Open-File Report 80-1114
The location and extent of 11 kinds of surficial deposits in part of Sandy Creek quadrangle, Oswego County, N.Y., are mapped on a 7.5-minute U.S. Geological Survey topographic map. The map was compiled to indicate the lithology and potential for groundwater development at any specific location....
Preliminary bathymetry: Approaches to Unakwik Inlet, Alaska
Austin Post
1980, Open-File Report 80-428
A map, scale 1:20,000, shows water depths, rocks, and hazards to navigation. These data are noted on track lines run by the Research Vessel Growler in Alaskan waters, where data on navigation shown on published charts are nonexistant, preliminary, or out dated. ...
Surficial geology of part of Boylston Center quadrangle, Oswego County, New York
Todd S. Miller
1980, Open-File Report 80-1115
The location and extent of seven kinds of surficial deposits in part of Boylston Center quadrangle, Oswego County, N.Y., are mapped on a 7.5-minute U.S. Geological Survey topographic map. The map was compiled to indicate the lithology and potential for groundwater development at any specific location....
Surficial geology of Orwell quadrangle, Oswego County, New York
Todd S. Miller
1980, Open-File Report 80-1116
The location and extent of 11 kinds of surficial deposits in Orwell quadrangle, Oswego County, N.Y., are mapped on a 7.5-minute U.S. Geological Survey topographic map. The map was compiled to indicate the lithology and potential for groundwater development at any specific location. ...
