365Caws is now in its 14th year of publication, and was originally intended to end after 365 days. It has sometimes been difficult for me to find new material, particularly during the winter months, but now as I enter my own twilight years, I cannot guarantee that I will be able to provide daily posts. It is my hope that along the way I may have inspired someone to a greater curiosity about the natural world. If so, I can rest, content in the knowledge that my work here has been done.

Letharia Vulpina
Day 240: Coming back from Yakima, I had already called for a "botany break." A little later, my companions decided to stop at the viewpoint for a lovely terraced waterfall and we were all heading down the trail together when a clump of distinctly chartreuse lichen on the ground caught my eye. All thoughts of scenic views evaporated in an instant, and as Maureen and Kosette proceeded to the overlook, I dropped to my knees to study it. Then looking up, I saw more colonies of it on the bark of several trees, much better specimens than the sorry and sodden example I had first noticed. However, the ones on the tree were well out of reach even with my arms extended over my head. Glad that I had left the macro filter on the camera, I snapped this photo without being able to tell if it was in focus or not. A sample taken from the clump on the ground confirmed the identification: Letharia vulpina, one of the "wolf lichens" used to dye textiles.
