The shale along the shore of the Vermilion River fascinates me no matter how many times I see and photograph it. It’s especially appealing when decorated with leaves.

I saw something at the edge of the river Saturday, September 27, that I’d never seen before. Checking my hunch with Norrie Robbins, my knowledge source for all things microbial, I learned that this white threadlike formation is evidence of sulfur-oxidizing bacteria. The black stuff around the edges shows the presence of sulfur-reducing bacteria. Since the shale in this area is replete with pyrite (fool’s gold), and pyrite is made of iron and sulfur, it should not have been a surprise.

The shale was a little wetter in this spot.

The brilliant colors of October foliage were beginning to wane two weeks ago. Walking to Schoepfle Garden October 22 I passed the neighbor’s leaf display that I’d passed 13 days earlier. Green had become gold and gold brown, but leaves were abundant there, and the overall effect was still quite brilliant. (You can compare the first photo in this post to the first photo in the post of October 12; some of the same trees are in both shots.) Down near the river, however, fall had made greater inroads. The shadow on the Birmingham Mills ruins foretells what is to come for almost all the deciduous trees in the northern climates this winter. (Young northern beeches and oaks tend to hold onto their old leaves until pushed out by the new ones in the spring. To learn why, go to http://northernwoodlands.org/articles/article/why-do-some-leaves-persist-on-beech-and-oak-trees-well-into-winter.) Meanwhile, some green persisted in some of the smaller plants. For years I wondered how or why insects chewed holes into leaves in a trail like the ones shown in the last photograph in this post. Finally, it hit me: They don’t chew a trail of holes; they chew a straight path through an unfurled leaf that, when it opens, looks like this.

Trees and other plants had begun turning color when I walked down to the river at Schoepfle Garden Sunday. I found more fallen leaves than the previous week on the shoreline, too. Next weekend the foliage should look significantly different; it already does, just beyond my studio window. . . . The first photo is a neighbor’s front yard that I pass on my way to the river. . . . Besides more colors, fall also brings more breeze to ruffle the surface of Schoepfle Garden’s Back Pond. The first three pond photos are from a week earlier.
