Timberlines are based on summer temperatures (where the average highest monthly temperature is 50 deg F), versus winter temps. The West is simply warmer relative to elevation in summer than the East (an 850 or 700 mb temperature map shows that almost all the time in summer). If you want to see even lower timberlines despite relatively mild winters, New Zealand has them--North Island around 4000' and the South Island as low as 3000'!
Anyway, Mt. Washington will be quite fascinating--I look forward to that (and hopefully will get "decent" weather but won't count on it!).
