Annual peak discharges from small drainage areas in Montana through September 1980
R. J. Omang, Charles Parrett, J. A. Hull
1955, Open-File Report 81-332
Annual peak stage and discharge data have been collected and tabulated for crest-stage gaging sites in Montana. The crest-stage program was begun in July 1955 to investigate the magnitude and frequency of floods from small drainage areas. The program has expanded from 45 crest-stage gaging stations initially to 172 stations...

Zinc and lead deposits of the Sinsinawa River area, Grant County, Wisconsin
John W. Allingham, Arthur E. Flint, Allen F. Agnew
1955, Miscellaneous Field Studies Map 40
A broad geologic study of the structure and ore deposits of the Wisconsin-Illinois-Iowa zinc-lead district (fig. 1) was begun by the U.S. Geological Survey in 1942.  The main object of the present program is to delineate the areas favorable to future exploration for zinc-lead ore deposits.  As part of the...

1955, Miscellaneous Field Studies Map 41
The Permian Phosphoria formation in the vicinity of the towns of Paris and Bloomington, Bear Lake County, Idaho, contains large tannages of vanadiferous mudstone and phosphorite.  The area underlain by these rocks was mapped in 1943 as a guide to the exploration of the vanadiferous zone then being conducted by...
Geology and zinc-lead deposits in the Durango area, Dubuque County, Iowa
Arthur E. Flint, C. Erwin Brown
1955, Miscellaneous Field Studies Map 33
Geologic investigations were begun in Iowa to appraise; (1) the possible occurrence of zinc ore in strata that elsewhere in the Upper Mississippi Valley zinc-lead district have been the principal sites of zinc concentration; and (2) lead ore of the type known as "crevice deposits," which were mined so extensively...

Geology and zinc-lead deposits in the Couler Valley area, Dubuque County, Iowa
C. Erwin Brown, L.G. Collins, Percy Crosby
1955, Miscellaneous Field Studies Map 42
Geologic investigations were begun in the Iowa portion of the Wisconsin-Illinois-Iowa zinc-lead district to appraise its potentialities: (1) for zinc ore in strata that elsewhere in the mining district contain large zinc ore bodies and (2) for lead and zinc deposits of the type that were mined extensively in Dubuque...
