From introduction: This report, one of a series of three reports (Marjaniemi and Robins, 1975a and 1975b) on a study of Tertiary sedimentary rocks in northeastern Washington, presents the results of an investigation of Tertiary sediments of the western Okanogan highlands and upper Columbia River valley. The project was conducted on behalf of the Energy Research and Development Administration (ERDA), formerly the U. S. Atomic Energy Commission.

Notes
Abstract: "Tertiary sedimentary rocks in the northern portions of the western Okanogan highlands and in the upper Columbia River valley were investigated during a regional study to determine the favorability for potential uranium resources of the Tertiary sedimentary rocks of northeastern Washington. This project involved measurement and sampling of surface sections, collection of samples from isolated outcrops, and chemical and mineralogical analyses of samples. No portion of the project area of this report is rated of high or of medium favorability for potential uranium resources. Low favorability ratings are given to Oroville, Tonasket, and Pine Creek areas of the Okanogan River valley; to the Republic graben; and to the William Lakes, Colville, and Sheep Creek areas of the upper Columbia River valley. All these areas contain some fluvial, poorly sorted feldspathic or arkosic sandstones and conglomerates. These rocks are characterized by very low permeability and a consistently high siliceous matrix suggesting very low initial permeability. There are no known uranium deposits in any of these areas, and low level uranium anomalies are rare" (p. 1)
