COSA Poison hemlock identification

I am looking for someone on the west slope who is very skilled at identifying poison hemlock in the field. I have a landowner who lives at about 8,200′ and their subdivision is home to what I can only determine is a mix of poison hemlock and various look-alikes. However, I’d love to bring someone up there who has more experience identifying it that can help both me and the concerned landowner with proper identification and differentiation.
