Field guide to sedimentary structures in the Navajo and Entrada sandstones in southern Utah and northern Arizona
This field-trip guide describes the common sedimentary structures that occur in eolian sands. The outcrops that are described occur in the Navajo and Entrada Sandstones between the areas of Page, Arizona and St. George, Utah (figure I), but the sedimentary structures of these two sandstones are typical of most eolian deposits. The main part of the guide discusses the geologic setting and the origi

Localized sudden changes in the geomagnetic secular variation.
There is much debate as to whether there was a worldwide geomagnetic jerk in 1969 or 1970. It is agreed that there was an unusual sharp change in the secular variation in the east component, Y, in Europe at that time. This note points out how a localized sudden change in the secular variation pattern of one component in Europe can occur without having any large worldwide effects in any of the comp

A comparison of the largest rainfall-runoff floods in the United States with those of the People's Republic of China and the world
The maximum historic rainfall-runoff floods measured in the United States, the People's Republic of China and the world all plot close to a smooth curve of drainage area versus discharge. In the United States, the possibility that flood peaks were overestimated and the closeness of these peaks to the probable maximum floods suggest that this limiting curve of maximum floods will not significantly

DEFORESTATION AND LANDSLIDES IN YUNNAN, CHINA.
Landslides historically have caused severe erosion problems in the Xiao River drainage region of northeastern Yunnan Province, China, that hence resulted in serious economic and social consequences. Owing to monsoonal storms of high rainfall intensity, the erosion potential is high in this mountainous, seismically active region. Landslides transported large quantities of materials into the ravines

The Steens Mountain (Oregon) geomagnetic polarity transition: 3. Its regional significance
Study of the variations of direction and intensity of the geomagnetic field as recorded by the Miocene lava flows on Steens Mountain, southeastern Oregon, has resulted in a detailed description of total field behavior during a reversal in polarity. In addition to information about the polarity reversal itself, the detailed paleomagnetic record includes several thousand years of geomagnetic history

Real-time landslide warning during heavy rainfall
A real-time system for issuing warnings of landslides during major storms is being developed for the San Francisco Bay region, California. The system is based on empirical and theoretical relations between rainfall and landslide initiation, geologic determination of areas susceptible to landslides, real-time monitoring of a regional network of telemetering rain gages, and National Weather Service

Hydraulics and basin morphometry of the largest flash floods in the conterminous United States
The maximum rainfall-runoff floods measured by indirect methods in small basins (0.39-370 km2) in the conterminous United States are examined. This analysis identified twelve floods that were the largest ever measured. These floods all occurred in semiarid to arid areas. For eleven of the twelve largest rainfall-runoff floods measured in small basins by the slope-area method, values of hydraulic d

Some effects of quiet geomagnetic field changes upon values used for main field modeling
The effects of three methods of data selection upon the assumed main field levels for geomagnetic observatory records used in main field modeling were investigated for a year of very low solar-terrestrial activity. The first method concerned the differences between the year's average of quiet day field values and the average of all values during the year. For H these differences were 2-3 gammas, f
