Under the twilight I prepared for my journey into a seldom seen world here in the Opal Creek wilderness. I had planned to dive the Battle Axe creek pool in Jawbone Flats to obtain some measurements for official purposes. Little did I know I would be in for an experience that I would not soon forget.
The water was as clear as ever and the temperature was just right (in the dry suit that is!!). I descended to the bottom of the pool and my gauge read 17 ft. I was about to start making my measurements then I noticed what appeared to be small pinecones on the bottom. I went in for a closer look and to my surprise there were dozens upon dozens of caddis fly larvae. I have seen them on the surface, but now that I was on their turf, I was amazed at the multitudes of these magnificent creatures. Some of the houses that these insects built were incredibly ornate. From pieces of bark, fragments of rock that seemingly glowed with copper, pine needles and whatever they can find. They were simply amazing. These insects can only live in water that is clean and free of pollutants. This is just another sign that this watershed is truly one of the most pristine in the western cascades.
In addition to these crafty critters, I came across some of the largest giant coastal salamanders I have ever seen. Rainbow trout were also very abundant and healthy. They ranged in size from 2 to 8 inches. Needless to say I spent my time just watching and being a guest in this pristine environment. My time limit of 15 minutes had quickly come to an end. Reluctantly I surfaced and shared my marvel with my on-looking co-workers. Opal pool is next!!
