Below is the side scan pass of the Valiant in Lake Washington. The image is wavy due to rough surface conditions during the imaging. Of note are is the large log to the south (right) of the plane. Divers diving this site from shore often run into this log and then navigate back to the plane.
This image was taken shooting up slope and hits the plane head-on giving a difficult picture. We dove the site to verify the image was indeed the Valiant.
