I have seen mt hemlocks growing in the north cascades in or near what you might consider eastern Washington. They experience dry spells in the summer and snowy winters. If Baker City has a similar climate it might be worth a shot trying to grow them there.I would like to collect several Mt Hemlocks for bonsai, but don't want to bring them home and have them struggle in this climate and then die. I live in zone 5-6 with low humidity sometimes and sometimes 100 F in summers. I can and will shade in summers when we have crazy high heat, have a good watering schedule, but I am a little concerned about the humidity getting as low as it does in the summer and fall. I could put a drip tray with water in it under the Hemlocks, but don't want to have to babysit them all the time. Baker City elevation is 3465'. Advice would be appreciated. Thanks!

You could always try growing a small mt hemlock from the nursery to see how it does. Then decide whether or not to go for the yamadori.
