Duncan, Hanna, McKean are all late archaic forms, of the McKean complex (even though I dispute it, don't forget Mallory). I'm very familiar with the McKean, and have played on many McKean sites. That doesn't appear to be McKean to me, but anything is possible. That piece has a distinct shouldered hafting area if you look closely at the image. If part of the McKean Complex, that would leave you with Duncan or Hanna. Hanna have VERY distinct lobes, resembling Jakie or Rice at times. Duncan have a longer hafting area, bifurcated base and are commonly confused with Johnson, Dalton or even Scottsbluff at times. In fact, there's one authenticator out there (won't mention names) who papers Duncans as Scottsbluff every single time..LOL. They are usually very well worked and have good basal grinding.
Bajada come in many forms, long and shorter stem, though the longer is more common. They are part of the Jay phase, and most likely have a relationship with the long stemmed Rio Grande and Escobas points. Some Bajadas I've seen can lack well-defined shoulders, have a shorter hafting area and can resemble Humboldt on occasion. They date in the Middle Archaic.
