This photo pair shows what is known as "Marmot Rock" or "Savage Rock" looking north, located near where the park road crosses the Savage River. When comparing the first two photos, note the addition of a stand of poplars at the base of the rock, and at least 12 spruce trees in the middle of the photo. When comparing the second two photos, which only span 9 years, what changes do you see? How many spruce are there now? Are these the same spruce that have grown up or are they new trees that have established? Note that in the 2010 photo it is late fall and many of the shrubs, and the stand of poplars at the base of the rock, have lost their leaves. What does comparing three photos, 72 years and 9 years apart tell you about the rate of change occurring?
