Having done a lot of this, it is sometimes hard to tell if it is a hole or a bump. It can become an optical illusion and be either. You have to zoom closer and see which side the shadows are from the trees to really tell.

That's why Google Earth is better. You can geta pseudo 3D view.

I'm looking at this now, centering on the coordinates above.

Meteor strikes that leave a large impact crater often had a trail of other pieces that left craters in a line in the direction of travel. If you look at this crater in Google Earth and then zoom out, it forms the center of other circular formations in a line from Prince Edward Island through this formation and into the Hudson Bay's Belcher Island formation. Is Belcher Island an impact upthrust?. Is Prince Edward Island an upthrust or collapsed crater rim?

Here is a zoomed out view of the region. Follow a line from west to east with the circle formation in this article in the middle.

It looks like Little Cultus Lake, Oregon to me. A volcanic formation.
