Reed College Aerial, 1940 Posted on July 17, 2013 by Vintage Portland 9 A nicely detailed top-down image of the Reed College, including parts of Eastmoreland, Westmoreland and Woodstock areas in 1940.

Are there overlapping views of the north field at Reed College? I ask because geologist John Eliot Allen claimed that there were giant ripple currents in the field from the ice-age floods. I have never found the original paper making the claim, so it would be great to do some stereo analysis. Thanks.
Broom Field was supposedly at Westmoreland park but south of SE Bybee that looks like a landing strip west of 99E
robotroyal – The paper you have in mind, I assume is “Giant River Channel Forms on Portland, Oregon,” by L Palmer. Alan included this reference in the 1986 edition of Cataclysms on the Columbia – and also noted that it was unpublished, hence your inability to find it. Alan et al mention the giant ripple bar at Reed in the 2009 edition of Cat on the Col but leaves the Palmer paper out of the bibliography, which I’m mentioning just in case you only have that edition of the book and were wondering why you couldn’t find the paper. They state that the east end of the campus is on the bar
Or perhaps you were a student of Alan himself? Last summer I was talking with the fellows behind the desk at Crown Point about the Troutdale Formation, Priest Rapids lava flow, etc. Turned out one of them had been in Alan’s classes.
That bar would show up more prominently on the USGS quadrangle map of the area. Probably that one’s available for viewing online, but there are surprising gaps in what’s available from the USGS for some reason – some maps are really out-of-date.
There are some really prominent ripple bars out in Yamhill County, in the Chehalem Valley south of Gaston, along Wapato Lake on Spring Hill Road. They don’t really manifest themselves as anything but ridges you drive over, but when you know they were created by flood waters hundreds of feet high you’re taken aback a bit, to say the least.
Woah! Thanks! I spoke with Professor Allen once on the phone. That was all. He donated a lot of photocopies to the Oregon Historical Society while he was alive, but I would love to know if the originals survived him.
You might check out this very cool LIDAR data viewer from the Oregon Department of Geology and Mineral Industries. Terrific detail on the underlying topography.
I’m pretty sure I got the email announcing the lidar viewer, but I had no idea it would be so polished. Quite amazing!
Reblogged this on Oregon Real Estate Round Table.
Wow, look at all that farmland!
Thanks for the link to the Lidar viewer, Dan. That’s pretty neat.
