At my height, the two trees showed no signs of change.

Aspen with green photosynthetic bark were common, but occurred in groups. Some clusters were obviously green, others were nearly white. As I mentioned last month, there's a theory out that aspen bark is thin because dead cells are shed each year, forming a powder on the surface. I tested several trunks, rubbing my finger on the bark, and decided ... well ... maybe.
The scouring rushes (Equisetum) along Pole Creek near my trees are much greener now—time to get busy with photosynthesis! Several had young cones.

|The brown scales of the cone have sporangia on their lower surface, which will mature to release spores.|
There was another nice surprise close by—a patch of pink wintergreen, Pyrola asarifolia.
