Georectified mosaics of historical aerial photographs of the Colorado River in Parker Valley, Arizona and California, acquired in 1930, 1938, and 1947 Georectified mosaics of historical aerial photographs of the Colorado River in Parker Valley, Arizona and California, acquired in 1930, 1938, and 1947
The products provided here include four georectified mosaics of historic aerial photographs for the Parker Valley region within western Arizona and southeastern California. There are three individual mosaics from 1930, 1938, and 1947 covering different geographic areas. The fourth georectified mosaic is a composite of the three and covers the entire area of interest. These datasets were...
Georectified mosaic of historical aerial photographs of the Colorado River in Mohave Valley, Arizona, California, and Nevada, acquired in 1938 Georectified mosaic of historical aerial photographs of the Colorado River in Mohave Valley, Arizona, California, and Nevada, acquired in 1938
This product is a georectified and tonally balanced mosaic of aerial photographs collected in 1938 by the U.S. Bureau of Reclamation along the floodplain of the Colorado River in Mohave Valley region of Arizona, California and Nevada. This dataset is a primary resource for the development of a geologic map showing the floodplain and river channel characteristics along the Colorado River...
Geospatial database for the geomorphic map of the Umatilla River corridor, Oregon Geospatial database for the geomorphic map of the Umatilla River corridor, Oregon
This map portrays the distribution of landforms along the Umatilla River in northeastern Oregon and covers a corridor 127 kilometers (km) long from the confluence of the Umatilla River with the Columbia River upstream to Meacham Creek. The map encompasses the valley bottom and extends about 1 km up the adjoining hillslopes. Map data are intended to support water quality and fisheries...
Argon ages near Parker, AZ, and Needles, CA Argon ages near Parker, AZ, and Needles, CA
Reported here are argon age data for samples collected to better understand lower Colorado River corridor landscape evolution, the history of the Colorado River, and define the age of geologic units being mapped. Samples of basalts, ashes, and sand were collected in the Cactus Plain southeast of Parker, AZ, the Whipple Mountain piedmont north-northwest of Parker, AZ and washes east...

Digital data for the geologic map of Scoggins Dam, Henry Hagg Lake, and Scoggins Valley, Washington County, Oregon Digital data for the geologic map of Scoggins Dam, Henry Hagg Lake, and Scoggins Valley, Washington County, Oregon
Scoggins Dam in northwest Oregon lies within the Gales Creek fault zone (GCF), a northwest-striking system of active faults forming the boundary between the Coast Range and the Tualatin Valley about 25 km east of Portland, Oregon. Geologic mapping published in 2020 shows the dam to lie within a block-faulted releasing stepover between the right-lateral, NW-striking Scoggins Creek and...
