An early Eocene florule from central Texas
Edward Wilber Berry
1925, Professional Paper 132-E
In 1916 I described a florule collected by Alexander Deussen and L. W. Stephenson at the town of Earle, in Bexar County, Tex. This florule was tentatively considered of Midway age by these geologists, and examination of the fossil plants tended to confirm this assignment, particularly because of their lack...
Rock formations in the Colorado Plateau of Southeastern Utah and Northern Arizona
C.R. Longwell, H.D. Miser, R.C. Moore, Kirk Bryan, Sidney Paige
1925, Professional Paper 132-A
The field work of which this report is a record was done in the summer and fall of 1921 by members of the United States Geological Survey. A project to build a large storage dam at Lees Ferry, on Colorado River in northern Arizona, called for a detailed topographic survey...
The resuscitation of the term Bryn Mawr gravel
Florence Bascom
1925, Professional Paper 132-H
In the course of geologic and physiographic work in eastern Pennsylvania, it has seemed to the writer that the time was ripe for the restriction of the term Brandywine formation, now including presumably both Pliocene and Pleistocene gravels, and the reinstatement of the old term Bryn Mawr gravel for a...
Aniakchak Crater, Alaska Peninsula
Walter R. Smith
1925, Professional Paper 132-J
The discovery of a gigantic crater northwest of Aniakchak Bay (see fig. 11) closes what had been thought to be a wide gap in the extensive series of volcanoes occurring at irregular intervals for nearly 600 miles along the axial line of the Alaska Peninsula and the Aleutian Islands. In...
The composition of the river and lake waters of the United States
Frank Wigglesworth Clarke
1924, Professional Paper 135
In the summer of 1903 the late Richard B. Dole, chemist of the water-resources branch of the United States Geological Survey, began a systematic investigation of the composition of the river and lake waters of the United States. His plan, which developed gradually, was to have analyses made of the...
The shapes of beach pebbles
Chester K. Wentworth
1923, Professional Paper 131-C
There is much confusion in geologic literature as to the shapes of fluvial and beach pebbles and the differences between them, if differences exist. Though the contrary has been asserted, most geologists who have written on the subject appear to hold the view that beach pebbles are generally flatter than...
Additions to the flora of the Wilcox group
Edward Wilber Berry
1923, Professional Paper 131-A
A rather full account of the extensive flora contained in the lower Eocene strata of the Mississippi embayment which are referred to the Wilcox group was published in 1916. At that time it was not possible to obtain sections of the numerous specimens of petrified wood that had been collected...
A section of the Paleozoic formations of the Grand Canyon at the Bass trail
L. F. Noble
1923, Professional Paper 131-B
The thick series of horizontal strata of Paleozoic age which makes the greater part of the wall of the Grand Canyon is probably broadly familiar to more people than the strata exposed in any other area in the western United States. Each detail of form or color in the wall...
