|Ghostly skeletons of Frasers emerge in the fog on Clingman's Dome as young trees grow around.|
|Treating on Clingman's Dome for BWA in early 90s with insecticidal soap.|
The soap was mixed in the white vat and a powerful pump was used to spray the product on the trees.
|They would spray the trees with fire hoses using many volunteers. |
Hard hats were required as the pressure spray might bring down limbs.
Today it looked different than I remembered. There weren't many tall Frasers, but there was quite a bit of healthy regrowth. Still, it looked like there was a lot more open ground than when I was there last.

The following are photographs from the visit.
|The tower today.|
|Lots of wildflowers are growing in areas left bare from dead trees.|
|The young trees coming on look good, but they are somewhat resistant to BWA as they produce juvabione.|
This is an insect growth regulator that keeps the insect from becoming mature.
|Larger trees stop producing juvabione and become infested. |
Each white spot covers an adult female which will lay a dozen eggs or so.
|The tree in the previous picture is on the left. It has no top left. Other trees around it still do.|
The loss of apical dominance is a symptom of BWA infestation.
|Even with the dying trees, Clingman's Dome is a popular destination.|
The steep walk to the tower and all the fog doesn't keep people from going to the top,
even if you have to stop to catch your breath along the way!
