This photo pair reveals two views of a subalpine pond above the Bull River in the Broad Pass region of the Park. One change you can see over the 30 year interval separating the two photographs is an increase in the density and size of the trees in 2005 relative to the earlier photo, especially in the area to the left of the pond. What might be causing an increase in the trees in this subalpine site?
