Analyses of rock samples from the Hunt Fork Shale and related Upper Devonian rocks, Philip Smith Quadrangle, Arctic Alaska
J. Thomas Dutro, David E. Detra
1978, Open-File Report 78-559
More than 1400 m of fine-grained clastic rocks and reefoid limestones constitute the lower part of an Upper Devonian transgressive-regressive cycle in the central Brooks Range, Alaska (Dutro and others, 1977). The Hunt Fork Shale and an underlying heterogeneous unit (unnamed) were measured and sampled on the east side of...

Analysis of runoff from small drainage basins in Wyoming
Gordon S. Craig, James G. Rankl
1978, Water Supply Paper 2056
A flood-hydrograph study has defined the magnitude and frequency of flood volumes and flood peaks that can be expected from drainage basins smaller than 11 square miles in the plains and valley areas of Wyoming. Rainfall and runoff data, collected for 9 years on a seasonal basis (April through September),...
Selected low-flow characteristics of streams in the vicinity of Warwick, Orange County, New York
Benjamin B. Eissler
1978, Open-File Report 78-811
Base flows were measured during 1971-76 at 10 partial-record sites and three continuous-record stations on major streams in and bordering the Town of Warwick. Discharge measurements at the partial-record sites were correlated with records from three suitable continuous-record gaging stations near the town to determine 7-day, 2-year low flows and...
Notes on availability of multi-channel seismic processing programs
Robert Brune
1978, Open-File Report 78-421
During the past two years, a seismic processing system has been developed within Western Region offices of the U.S. Geological Survey (Pacific-Arctic Branch of Marine Geology). This brief report describes some of the programs within this system that may be of value to others. We process seismic reflection data taken...
