Hi, A kind of footnote to my previous Post: the elevations of the "round feature" are highly inconsistent. Much of the "rim" is hundreds of feet lower than the highest spot inside the "rim," and almost none of the rim is higher than the interior.
The "rim" is higher than the surrounding general terrain in most places. The rim has a "braided" topography, another un-crater-like feature and it seems that the feature is elevated as a whole above the surrounding terrain, not a likely thing for a crater to be. The center of the "crater" has both high and low areas close to each other. The elevations are complex and hard to interpret. The closer I zoom in, the less like a relict crater it looks to me.

I've been meaning to get over and explore that general area. Of course it would have to be pretty obvious for me to notice anything :-) By the way, I have heard a theory that there was a large strike at some point in central Oregon causing a "hot spot" in the mantle (?) which has since migrated through the Snake River plain in southern Idaho and now lies beneath Yellowstone National Park resulting in all of the geothermal activity in that area.
