I don't think that's the oak native to Oregon - garryana.
Your photo shows leaves that widen toward the end, and the full view of the tree - the form doesn't look right.
Oregon oak leaves are round lobed, but the leaf is narrow at the petiole, and then the middle lobes area is wider, then it reduces width toward the end.
Like a lobed oval, or lobed orb. It's usually not a very big leaf either.
I think my mom ran off with my ID book - wouldn't you know it - the only day this month I want to look at the page of leaf shapes.
Your leaf looks closer to the shape of alba in Dirr's book - but there must be a dozen oaks that share your leaf shape.
I can't vouch for my screen color settings, but the photo you posted last, seems to show a purple or colored twig. I think garryana is either green or green/gray.
