Washington, November 7, 1934.

This publication covers the coast and interior waters of the States of California, Oregon, and Washington. It is based mainly upon the work of the Coast and Geodetic Survey, including the results of special examinations in 1933.

The first volume covering this area, entitled "Directory of the Pacific Coast of the United States ", was prepared by George Davidson, Assistant, Coast and Geodetic Survey, and published in 1858.

The present edition (which is the fifth) has been prepared by Lt. L. D. Graham, United States Coast and Geodetic Survey, under the supervision of Comdr. F. B. T. Siems, chief, coast pilot section. Great courtesy has been shown by the Lighthouse Service, the United States Engineers, and local authorities in furnishing information for use in this publication.

The aids to navigation are corrected to November 7, 1934.

Navigators are requested to notify the Director, United States. Coast and Geodetic Survey, of any errors or omissions they may find in this publication or of any additional matter which they think should be inserted for the information of mariners.

R. S. PATTON, Director.

NOTE

The courses and bearings given in degrees are true, reading clockwise from 0° at north to 3590, and are followed by the corresponding magnetic course in points, in parentheses. General directions, such as northeastward, west-southwestward, etc., are magnetic.

Distances are in nautical miles and may be converted approximately to statute miles by adding 15 percent to the distances given. Currents are expressed in knots, which are nautical miles per hour. Except where otherwise stated, all depths are at mean lower low water.

In accordance with the desire of the International Hydrographic Bureau, each depth is followed, in parentheses, by its equivalent in

meters.

Heights are given in feet with metric equivalent in parentheses. Changes and other corrections affecting all coast-pilot volumes are included in the Notice to Mariners published weekly by the United States Department of Commerce. About 1 year after a Coast Pilot is published, and at approximately yearly intervals thereafter until a new edition is brought out, a supplement, giving the more important corrections and additions to its text since the date of its publication, is issued. The date of the latest supplement to each Coast Pilot, for which a supplement has been issued, is shown at intervals in the list of Coast Pilots published each week in the Notice to Mariners. Any supplement may be obtained, free of charge, upon application to the Coast and Geodetic Survey, Washington, D.C., or any of its field stations. Each supplement is complete in itself and cancels all previous supplements.

Do not use this Coast Pilot except with reference to the latest plement that may have been published and Notices to Mariners issued after the date of the supplement.
