Denali Park Headquarters - then and now! These two photos show the view to the south from the Denali Park Road looking down the side road into Park Headquarters, sixty years apart. The most obvious difference is the dramatic increase in the number, size and stature of the trees between the two dates. Also notice the increase in broadleaved species in the recent photo, whereas all the trees visible in 1940 were white spruce (Picea glauca). Aspen (Populus tremuloides) and Alaska Birch (Betula neoalaskana) thrive in the mineral soil exposed by disturbance, so it is not surprising that these species have moved into this area so visibly over the past 60 years, with considerable ground disturbance resulting from people's activities in the area.
