Alluvial fills near Gallup, New Mexico

Valleys near Gallup, N. Mex., similar to many in the Southwest, were filled in Recent time with alluvium. This material is now being eroded by systems of gullies, and the walls of these gullies provide exposures by which the history of the deposition of the alluvium can be traced. Alluvial fills near Gallup have been eroded at least twice previously within Recent time. The middle fill of the three that are recognizable contains potsherds of Pueblo II age, indicating that deposition was occurring as late as A. D. 1200. The chronology of alluviation and degradation for valleys in the Gallup area appears to agree with that for other valleys in the Southwest which have been studied.

Ground water in the Cuyama Valley, California

This is the fourth of a series of interpretive reports on the water resources of the major valleys of Santa Barbara County, Calif., prepared by the Geological Survey, United States Department of the Interior, in cooperation with Santa Barbara County. The first three reports described the other major valleys in the county: the south-coast basins, Goleta and Carpinteria, and the Santa Maria and Santa Ynez River valleys. This report deals with the Cuyama Valley in the northeastern part of the county and adjoining parts of San Luis Obispo, Kern, and Ventura Counties. It includes estimates of natural discharge, pumpage, and yield of ground water, and all data on water levels, well records, and water quality that were available up to June 1946.
