Stromatolites of the Belt Series in Glacier National Park and Vicinity, Montana
Richard Rezak
1957, Professional Paper 294-D
Eight zones of Precambrian stromatolites that are useful for local correlation are recognized in the Belt series of the Glacier National Park region, Montana. The zones vary in composition, thickness, and areal extent. Some are widespread and extend into neighboring regions, and others occur only in small areas. Their names...
Bedrock geology at the south-central part of the North Range, Cuyuna district, Minnesota
R. G. Schmidt, C. E. Dutton
1957, Miscellaneous Field Studies Map 99
The Cuyuna iron-ore district is in central Minnesota in Morrison, Crow Wing, and Aitkin Counties.  The length of the district is about 68 miles, extending from near Randall in Morrison County ot a point 11 miles east of the community of Hassmann in Aitkin County, and the maximum know width...
River flood plains: Some observations on their formation
M. Gordon Wolman, Luna Bergere Leopold
1957, Professional Paper 282-C
On many small rivers and most great rivers, the flood plain consists of channel and overbank deposits. The proportion of the latter is generally very small.Frequency studies indicate that the flood plains of many streams of different sizes flowing in diverse physiographic and climatic regions are subject to flooding about...

The length of the...
Construction and use of special drawdown scales for use in prediction of water-level changes throughout heavily pumped areas
C.S. Conover, H.O. Reeder
1957, Open-File Report 57-24
Problem and Proposed Method of Solution Frequently the Theis nonequilibrium formula is use din the quantitative analyses that are part of many-ground-water investigations. The computations associated therewith may become quite involved and tedious, especially when dealing with predictions of the decline of water levels throughout large areas in which there are...
Occurrence of ground water near Ana Springs, Summer Lake Basin, Lake County, Oregon
S. G. Brown
1957, Open-File Report 57-17
Ana Springs are near the north end of Summer Lake Basin, a closed fault-block basin in Lake County Oregon. The water of the springs rises by artesian pressure from lava-rock aquifers through about 150 feet of overlying thinly bedded lake deposits to discharge at the bottom of an impounding reservoir,...
