The last time beatles invaded Colorado was 1964 and they only made it to the foothills of the Rockies. As the story goes, they were here for less than a day. And although they appeared at the storied Red Rocks amphitheater in Morrison for only about 35 minutes, they were able to inflict a considerable amount of their brand of "destruction" in that short time.
In terms of the most recent beetle invasion, however, it appears the visitors will be around for much longer -- and inflict a brand of destruction on the Rocky Mountain landscape that will, in retrospect, make John, Paul, George, and Ringo look merely like four harmless, long-haired kids from Liverpool who smoke cigarettes and play some newfangled kind of music that all the kids seem to love. And yes, even these beetles will not be loved by Boulderites.
I am speaking of course about the ubiquitous mountain pine beetle which is happily chewing its way through the vast coniferous forests of the North American continent. These beetles have yet to make their way to Red Rocks, but by the time they do, the damage will have been done.
Pine beetles, bark beetles and spruce beetles have always been part of the ecosystemic processes in the forests of Colorado. However, within the last 10 years, beetle populations have proliferated.
