Penny Postcard, Postmarked 1935, "Happy Dell Auto Camp - Viento, Oregon - Columbia River Highway." Sawyer image. Card 14-909. Card is postmarked September 8, 1935. In the private collection of Lyn Topinka.
I need to try and get locked in on the angle on the bluffs to pinpoint this location better. Best bet right now? Square under the interstate. Might make getting a matching shot difficult!
The photo above was taken from the westbound lanes of I-84, so it appears that the Auto Camp would have been a little west from here. Under the freeway, south of the current Viento Trailhead?
