Submitter does not have a specimen
It was about 1.5" long. The stinger seemed a bit more prominent than in the photos I have seen. It looker very much like the photos online. It was on the sidewalk. I did not think to take a photo, it seemed to be resting so we quickly stepped on it. I am a gardener and am familiar with native bee species and this did not remotely look like a native bee.
I will ho back today and see is the remains are still there and collect them in case they would be of help
In Oregon we have many different lookalike species and this poster highlights just a few of them: AsianGiantHornetLookAlikesPoster.pdf. Given your location and description I would guess the insect you saw was a Cicada Killer in the genus: Sphecius. They are probably our most convincing hornet look-a-likes as they are very similar in overall appearance.
Thank you for your interest in keeping invasive species out of Oregon!
