Beetle Outbreak Threatens Park Trees: Researchers Say Global Warming May be to Blame -
Take a walk through Rim Village this summer and you will notice several things: fantastic views, smiling park visitors, and-from one end of the village to the other--dead pine trees.
The dead trees are obvious, but the cause of the death may not be. A tiny beetle, rarely seen, is responsible for most of the damage. Scientists indicate, however, that the real culprit may be our

these various specialists have come to the
conclusion that Crater Lake is young, not
yet 1,000 years old.
