This movie was taken on the Columbia River on 2nd May 2012, for The Kennewick-Man Expedition. A whole route map of this day can see in the map below.
It was a strong wind along the river from downstream as west. As a zigzag track in the map below, sailing downstream against powerful head wind was very difficult, and I could only just move back and forth in the width direction of river, could not move downstream, for some time after start. I was almost given up kayaking in this day twice.
強い川下からの風が、川に沿って吹き荒れていました。その強烈な向かい風に逆らって下流に帆走することはとても難しく、地図上のジグザグした軌跡から見て取れるように、出発後しばらくは川を下ることができずに川幅方向を行ったり来たりするのが精一杯でした。二度、この日川を下ることを諦めかけました。
