There are actually several "sites" in the ship canal. These are ancient indian fishing grounds. When I used to moor in Lake Union and go through the locks I would encounter nets all the way across in the middle of the night from time to time making navigation into the lake impossible. I remember calling the coast guard one time and they told me to call the tribes....DUH??? like I could hail them on the VHF at midnight. I had to tie up and wait for the nets to come out before getting back to my slip in the lake....all night. Does anyone have any pictures of what the ship canal looked like in the 1800s?
