Spring Tiptoes In—5


May 4, 2018

It is tempting to think that all of spring came rushing in to Oberlin Tuesday, when our temperatures soared to the lower 80s. Nearly every tree that possibly can, has burst into bloom. But here and there, as with the vines on the wall marking the back boundary of the library property, progress is a little slower.

But apparently stationary ones do. See the third photo for context. Click on the image to see a higher-quality file.

I pass this slab of quarried sandstone nearly every time I visit Schoepfle Garden. It never looks the same. The first photograph is from my trip this past Sunday, April 14. The second is from about a year ago, April 18, 2017, and the third is from August 26, 2017. I know there are others . . .

 

 

 


Hosting (Lichens, Algae)

This is the same tree (a bald cypress at Schoepfle Garden) that sheltered a snow remnant a few weeks ago.


Back to the Garden 3

I tagged this photograph with “lichen,” but I’m not really certain that the white marks on the large rock are lichens. What else could they be? Fossils in the stone?

Later in the Day

Scientist-husband David suggests “mineralized inclusions in the rock. Could be of biological or abiotic origin from what little I can see.”

Evening Update

We now have two more opinions favoring the lichen theory: One is from my husband’s colleague in the Oberlin College Department of Biology, and one is from Art Murphy, who usually knows a fossil when he sees one. (See Art and Fossils.)
