Seismic reflection profiles from cooperative investigations in the Straight of Juan de Fuca by the U.S. Geological Survey and Geological Survey of Canada aboard the Canadian Survey ship Parizeau between May 15 and June 3, 1972; Part 1 (easternmost segment)

In order to develop new data pertaining to the tectonic setting and potential geologic hazards in the Strait of Juan de Fuca and northern Puget Sound, a cooperative seismic reflection profile, gravity, and magnetic survey was conducted aboard the Canadian Survey Ship PARIZEAU in 1972. Results of approximately 2300 km of gravity and magnetic trackline data have been published by Snavely and others (1974), Tiffin and others (1974), and Macleod and others (1977). A map, based upon interpretation of about 700 km of seismic reflection profiles in the easternmost part of the strait, is nearing completion by H. C. Wagner and M. C. Wiley of the U.S. Geological Survey. The seismic reflection profiles in this area are being released at this time.

Mineral appraisal of the Flattery Rocks, Quillayute Needles, and Copalis National Wildlife Refuges, Washington

The Flattery Rocks, Quillayute Needles, and Copalis National Wildlife Refuges lie off the Pacific coast of the Olympic Peninsula between Cape Flattery and Grays Harbor. They have a total land area of 247 acres and consists of numerous small islands, sea stacks and rocks that rise above a wave-cut platform. The refuges are in a belt of intensely folded and faulted marine sedimentary and volcanic rocks of early Eocene to Pliocene age. Pleistocene glaciofluvial deposits blanket the Tertiary strata along this coastal belt. The disturbed belt borders the eastern margin of a depositional basin on the continental shelf that probably contains a thick sequence of late Tertiary rocks.

Geology of the eastern part of the Centralia - Chehalis coal district, Lewis and Thurston Counties, Washington

This report gives the results of geologic investigations made in 1948 and 1949 in the eastern part of the Centralia-Chehalis coal district of southwest Washington. Detailed geologic mapping and stratigraphic studies were supplemented by core drilling. The core drilling tested the thickness and physical character of the individual coal beds and aided in determining the continuity of the beds. It is hoped that the information on coal resources thus obtained will provide basic data useful in the development and utilization of the coal, which furnished one of the natural bases for the potential industrial growth of this region. Exploratory drilling for oil and gas has been thus far unsuccessful and suggests that geological conditions in the area mapped are not favorable for the accumulation of petroleum; the geologic information obtained during this investigation may, however, be helpful in delimiting areas in other parts of western Washington that may be favorable for exploratory drilling.
