Dramatic changes to the vegetation around the Camp Denali wilderness lodge at the base of the Kantishna Hills can be seen by comparing these two images, taken 57 years apart. Note the dramatic increase in the density and size of trees that has occurred in the period separating these two images, both around the lodge and on the hillside in the background. You can clearly see a landscape in transformation with the spreading of white spruce (Picea glauca) across the area.
