Description:
*This description was written by teachers who visited the park in June 2012 to learn about communicating climate change. This is a view looking northwest from the Toklat Bridge. There are several noticeable changes in vegetation when compared to the original photograph taken in 1958. One noticeable change is the continued advance of shrubs up the ridge. Not only is the shrubline advancing in altitude, previously existing shrub areas in 1958 are now more dense. Another noticeable change is the addition of poplar stands. Noticeable stands can be found in the left-hand side of the photo and one above the spruce stand in the center of the photograph. Also note the continued expansion and increased density of the spruce. The change in vegetation along the gravel bar is also striking. In 1958, the gravel bar was barren but in 2001 there are ample amounts of low vegetation to be found around the gravel bar. A noticeable human impact at this site is the addition of the rest stop which can be seen in the lower middle part of the 2001 photograph.
