In 1929 the Alaska Road Commission worked near the summit of Sable Pass building the Denali Park Road. Pictured here is one of their camps. By 2001 you can see that this alpine area is now supporting more woody vegetation, with 0.5-1 meter tall willows present throughout the area that the camp existed. Do you think the disturbance caused by the camp could have given the willows an advantage to establishing in this area?
