Human development and impacts
Description:
The Denali Park Road’s precarious location through Igloo Canyon and along Igloo Creek has necessitated several road realignments. Shown here is the development of a sturdier and wider bridge. Do you notice any other changes in this photo pair? Woody vegetation has thickened along the slopes of Cathedral Mountain, both in the photo foreground, just beyond the bridge, and on the upper slopes visible in the photo background. How do you think this increase in shrubs has affected movements of sheep commonly seen in this area?
