You can see at the top of the photo that Hayden Island and Tomahawk island were still separate at this time
I believe the track at that time was an auto race track, is this the same as the present horse race track and grandstand?
May be seeing Paul Bunyan before his big move across Interstate ~
Notice the abandoned streetcar trestle coursing diagonally across the Columbia Slough and the bridge to Tomahawk Island. This bridge would collapse in early 50’s and be removed.
@Jeff. Some of the supports for that streetcar trestle are still there. I had my boat moored there and one of the older guys told me about riding that streetcar.
Is that a drive in movie theater just East of the racetrack?
Similar modern perspective:

Do I see the white wooden roller coaster at Jantzen Beach in the upper left corner west of Hwy 99 just before the bridge?
re: 1947, and “the remnants of East Vanport”
Never heard of East Vanport. Was it abandoned/demolished before the 1948 flood?
“I believe the track at that time was an auto race track”
Kenn, The larger track, Portland Meadows, was always a horse racing track. The auto race track is the smaller paved track right next to it to the northeast (the one that also apparently had a drive-in).
Remnants of the streetcar trestle:
That’s definitely the roller coaster at Jantzen Beach, and a big grove I’m guessing of cottonwoods.
Portland Speedway and Drive In is the smaller oval. Demolished I think about 2000 to become eventually a trucking company yard.
Paul Bunyan was not constructed until several years later.
Oops, Forgot to mention Kaiser Shipyards…
If you look at the right edge of the picture, behind the horse track (top right corner) you’ll see rows of long buildings. If I remember right, these are horse stables.
Kenton Hotel and Safeway on Denver
Drive in theater was in the center of the auto racetrack ~
