Changing Treelines at Teklanika River: 1958-2001

A photo pair showing Changing Treelines at Teklanika River: 1958-2001

In this remarkably matched photo pair, one can line up individual trees and see how successful they have been at reproducing! Taken off the park road along the Teklanika River, these photos capture a trend of increasing spruce across much of Denali's landscape. What physical controls do you think are loosening to allow this increase?

Original year: 1958; Rephoto year: 2001
