“…This structural high, which extends about 40 Ian in a northnorthwestward direction, is defined mainly by an exposed core of Crescent Formation-Eocene pillow basalt, basaltic breccia, and basaltic sedimentary rock (Wagner, 1967a(Wagner, , 1967b. Near the northern and southern ends of the antiform the Crescent is flanked to the east and west by younger sedimentary strata of Eocene and Oligocene age.…”

“…Flanks of the antiform trend parallel to synclines that deform rocks as young as Miocene (Figure 4). Net Quaternary uplift is shown by estuarine and shallow marine deposits of probable Pleistocene age; Wagner (1967aWagner ( , 1967b mapped such deposits on the antiform to altitudes of 180m. However, uplifted Pleistocene estuarine deposits extend beyond the antiform as well: they border much ofWillapa Bay and Grays Harbor (Clifton, 1983;Walsh and others, 1987), and they even form a terrace in a Neogene syncline along the Naselle River (Wells, 1989) …”

“…This project provided additional foraminiferal information and allowed an extended application of the foraminiferal zonation of southwest Washington (Rau, in Wolfe and McKee, 1972). Support of U.S. Geological Survey geologic mapping in the western part of the Grays Harbor basin (Gower and Pease, 1965;Wagner, 1967) further extended the foraminiferal biostratigraphy of Washington to this area (see Fig. 1).…”

This report presents a compilation of 1,019 paleontologic dates and 301 isotopic dates of rocks in southwestern Washington and northwestern Oregon. The study area extends from Portland, Oregon (latitude 45°30' N.) to Bellevue, Washington (latitude 47°35f N.) and from the east flank of the Cascade Range (longitude 121°20f W.) to the coastline (longitude approximately 124°00f W.). The data are presented in two tables and come from previous summaries of isotopic ages, open-file reports, published papers and maps, and theses. Parke D. Snavely, Jr. of the U.S. Geological Survey and Weldon W. Rau of the Washington Division of Geology and Earth Resources (WDGER) generously allowed us access to files and records of more than 40 years of micropaleontological research in western Washington and Oregon. We also present unpublished data from our research since 1971 in northwestern Oregon. This compilation was undertaken for the southwestern Washington and northwestern Oregon project of the U.S. Geological Survey Evolution of Sedimentary Basins Program. Data compilation was completed in only three months and, therefore, some available data may have been overlooked. We would appreciate being contacted about omissions through:
