Hello.
This appears to be a Great Golden Digger wasp (Sphex ichneumoneus) ~ fairly common in western Oregon.
Please note that it is impossible to verify IDs without examining the specimen under the microscope . . . but given the time of you, area, and general appearance of this wasp, Sphex ichneumoneus is the best bet.
