This book documents the relay along the PCT in the four summers of 1935 thru 1938 to discover and map the route of the proposed PCT from Mexico to Canada. Many famous names are recorded in this document as the relay moved north: including Norman Clyde, Francis Tappan, Ernest Dawson, Francis Farquhar, and many USFS and NPS rangers. This book, #79 of 130, was issued in 1968 by Warren Rogers, and is very rare.
