The Nature of Cima Dome

In the Mojave Desert of southeasternmost California is a remarkably smooth, symmetrical rock-alluvial dome which takes its name from Cima on the Union Pacific Railroad. Lawson (1915, pp. 26, 33) cited Cima Dome as a prime example of a panfan, but Thompson (1929, p. 550) later showed that its upper part is bare rock. Davis (1933, pp. 240-243) considered it a fine example of a convex desert dome evolved from back-wearing of a fault block, but this concept is contradicted by the geological relations (Hewett, 1954), which throw more light on the nature and origin of Cima Dome than do geomorphological theories

Earth science field work: Role and status

This essay contends that the outstanding contributions currently being made to the earth sciences by theoretical and laboratory endeavors increase rather than decrease the need for sound field observations. The presentation is strongly prejudiced in favor of field studies and, accordingly, invites critical examination by skeptical minds

Physiographic Features of Faulting in Southern California

The abundance and variety of faults in southern California provide good opportunity for study of landforms created directly by faulting or indirectly by other processes acting upon faulted materials. High-angle gravity faults, high- and low-angle thrusts, and faults with large strike-slip displacement are present (see Chapter IV). Furthermore, all degrees and dates of activity are represented. Landforms created by faulting can be classed as primary and secondary, or as original and subsequent (Lahee, 1952, p. 248). Primary features are those formed by actual fault displacement. They are nearly always modified by erosion, but should be classed as primary until completely effaced. Secondary or fault-line features are those formed solely by other processes acting upon faulted materials. Further subdivision into initial and modified primary forms and into erosional and depositional secondary forms would be possible, but it is not urged

Geomorphological processes on terrestrial planetary surfaces

This review deals with features and processes on planetary surfaces, first by examining the impact of photographic explorations of Moon, Mars, and Mercury on studies of surface processes on our own planet, and second by treating matters related to current deformation of Earth’s surface

Some Physiographic Aspects of Southern California

Southern California is a land of physiographic abundances, contrasts, and peculiarities. The wide range of geological materials and structures, the considerable differences in climatic environments, the host of geological processes at work, and the recency of diastrophic events are the principal factors responsible

Principles of Structural Glaciology [Book Review]

The title of this volume, although appropriate, is not really indicative of its content. It becomes more than a book on structural glaciology through its detailed treatment of many facets of glaciology, which the author defines as the science of natural ice in all its aspects. People interested in ground ice, sea ice, lake ice, glaciers, and snow, among other topics, will find much of value in this book. Shumskii professes to have a primary interest in the petrology of ice rocks and the laws of their formation, but he carefully develops a foundation of basic information before treating the specific topics of structural glaciology

A report on Caltech's third season of field studies on Alaskan glaciers

Glaciers in the Arctic

Contains a compilation of literature and available data on arctic glaciers, originally prepared for Encyclopedia Arctica in 1949, and brought up to date. Ahlmann's morphological classification of glaciers is given, and the distribution, area, volume, and present regime of the glaciers is described. Regional treatment follows: Greenland, Iceland, Jan Mayen, Svalbard, Novaya Zemlya, Zemlya Frantsa-Iosifa, Severnaya Zemlya, also other small Siberian islands, are considered in turn, and their glaciers characterized; similarly: Scandinavia, the Urals and continental Siberia, continental Canada and Alaska, also Ellesmere, Baffin and Bylot, Devon, Axel Heiberg, Meighen, and Melville Islands in the Canadian Arctic Archipelago
