Bob and Jess, Not disagreeing, but higher elevations in a more southerly location is not the same with lower elevation in a more northerly setting in terms of length of daylight, angle of incidence, and likely not even in growing season. They may share cooler temperatures on average, but parameters of daylight is different, ad the Smokies and mountains in Georgia may also incorporate a higher amount of rainfall that many areas farther north.

Interesting species profiles. Bigtooth Aspen appears to be another that reaches a height maximum north of the geographical center of it's range within the lower 48. Do you agree?
