I drove to a small and somewhat remote lake in the Wallowas based on a 1964 report of that location as a D. anglica site. Sure enough, when I arrived there a bog bordering the lake had a large population of D. anglica in full bloom. As I walked across the mat for the first time, I neared the edge of the bog, where I assumed the lake began. Suddenly, my footing became unsteady and I glimpsed a shear 10 ft. drop at the lake edge. I was standing on a floating sphagnum mat. This was my first trip to a quaking bog.
There were several acres of bog, and D. anglica was present and almost predominant on most of it. One interesting thing was the large number of dragonflies caught on the plants. I had seen captured damselflies in Barry's pictures, and though these were very present here as well, many of the much larger and stronger dragonflies had also been caught.
Anyway, on to the pictures:
The thickness of the sphagnum ranged between 30 cm. and 5+ m.
