This photo pair depicts two views of the Mt. McKinley National Park/Denali National Park and Preserve Headquarters area separated by more than a half-century. Rock Creek is seen on the right in both photos, and Hines Creek is shown below the developed area in the 1947 image. Note the expansion of development that has occurred over this period, with new roads and structures increasing the human footprint in this area. Also, note the dramatic increase in vegetation along the Rock Creek floodplain, which appears to be very open in 1947, but almost completely vegetated by the 2004 image date. What other changes can you observe between the two photos?
