Stratigraphic relations of the Shakopee dolomite and the St. Peter sandstone in southwestern Wisconsin
Arthur Emerson Flint
1953, Open-File Report 53-71
This paper is concerned with the origin and geologic history of the boundary that separates the widespread St. Peter sandstone from the underlying Shakopee dolomite. That international surface is highly undulatory, and most contemporary geologists who have examined it believe that the contact irregularities result from pre-St. Peter subaerial erosion...
Geology of the Olds Mountain-Clark Peak area, Juneau and vicinity, Alaska
C.L. Sainsbury
1953, Open-File Report 53-231
The area under study lies about ten miles east of Juneau, Alaska, and includes the bedded rocks adjacent to the Coast Range batholith, and intrusive rocks related to the batholith. Deep glaciated valleys and glacially scoured rocks are the major topographic features. The relief is about 3,500 feet, and the highest...
A preliminary report of geochemical investigations in the Blackbird District
F. C. Canney, H. E. Hawkes, G.M. Richmond, J. S. Vhay
1953, Open-File Report 53-31
This paper reviews an experimental geochemical prospecting survey in the Blackbird cobalt-copper mining district. The district is in east-central Idaho, about 20 miles west-southwest of Salmon. The area is one of deeply weathered nearly flat-topped upland surfaces cut by steep-walled valleys which are tributary to the canyon of Panther Creek....
The hydraulic geometry of stream channels and some physiographic implications
Luna Bergere Leopold, Thomas Maddock Jr.
1953, Professional Paper 252
Some hydraulic characteristics of stream channels - depth, width, velocity, and suspended load - are measured quantitatively and vary with discharge as simple power functions at a given river cross section. Similar variations in relation to discharge exist among the cross sections along the length of a river under the...
