The scenic beauty, rugged contour, and great variety of geologic phenomena displayed by the San Juan Mountains of southwestern Colorado have lured to that region many geologists, both professional and amateur, as well as countless laymen. Serious geologic studies in these mountains seem to fall historically into three periods. The first...

Investigations of the fluctuations of the ground‐water table in Pennsylvania
S.W. Lohman
1932, Eos, Transactions, American Geophysical Union (13) 373-375
Hydraulic engineers are interested in ground‐water as a source of water supply and also as it affects stream‐flow. The stream‐flow is especially valuable at low stages and it is at the low stages that it is most closely related to the ground‐water conditions. For several years the Pennsylvania Topographic and Geologic Survey and the United States Geological Survey have...
Recent investigations of Thiem's method for determining permeability of water‐bearing materials
L.K. Wenzel
1932, Eos, Transactions, American Geophysical Union (13) 313-317
This paper presents results obtained in an investigation of the ground-water resources of the Platte River Valley that is being conducted in cooperation between the Conservation and Survey Department of the University of Nebraska and the United States Geological Survey.Most quantitative ground-water studies are concerned with the amount of water...
Investigations of the fluctuations of water‐levels in observation‐wells in Virginia
R.C. Cady
1932, Eos, Transactions, American Geophysical Union (13) 370-373
An automatic water‐stage recorder has been maintained on an observation‐well in Arlington County, Virginia, about 1‐½ miles from the United States Weather Bureau, in Washington, D.C., since June, 1928, but there are a few interruptions in the record. This is a dug well, about 28 feet deep and extends through terrace deposits of gravelly silt or loam. It has not...
A preliminary report on the artesian water supply of Memphis, Tennessee
F. G. Wells
1932, Water Supply Paper 638-A
Memphis is located in the part of the Gulf Coastal Plain known as the Mississippi embayment. It is underlain by unconsolidated sand and clay formations of Tertiary and Cretaceous age. The Wilcox group, of Tertiary age, and the Ripley formation, of Cretaceous age, are excellent aquifers, and all the water...
