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 . . .

    I think you’re onto something Linda. Have you ever thought of photographing this slab using the exact same framing over a period of time? That way, the changes from one image to another would be the only variable and make for a fascinating exhibit or printed piece.

    • I have thought of that with respect to other photographs I’ve taken, but not this one. The trick is to remember exactly how I took the previous one(s). But I’ll start doing that (or trying to) now with this slab. Thanks for the push, Alan.

  2. Having come from a region that has a number of serpentine rock outcroppings, and serpentine coloring the streams, I’m partial to the last photo – it has that same blue-green color I’ve been admiring in Oregon & California. Interesting how the seasons change the lichens on the rocks.

    • I wasn’t aware of the changing color of the lichens until I put these photographs together. . . . I didn’t know about serpentine rocks, so I had to Google. Interesting.

      • I don’t know anything about lichens changing colors either – but don’t they, or some of them, have blue-green algae as constituents, or something along those lines? Could that increase/decrease and affect the color? I’m probably way off….
        The trip was (as usual for me) a bit of a “Let’s go see this, let’s go see that, rush around” so I didn’t spend time really understanding the habitat, but the bits I saw were interesting. The chemistry/biology of it – what the minerals and other soil characteristics do to the plant life – is fascinating.
        We were brought (by a fellow blogger) to an obscure bog, way down a dirt road, where we waded across a shallow creek and found thousands and thousands of pitcher plants! It was a flabbergasting sight. Later on I wished I could have sat down and watched until an insect landed on a plant and disappeared! That would be cool to see. Maybe there’s a serpentine area somewhere near you.

        • I still don’t know about the changing colors, but you are absolutely right about the blue-green algae (cyanobacteria) being a component of lichen. Look at Click on the first photograph, and you can cycle through many photos of lichens, maybe most of which I’ve never seen. Very cool. The Wikipedia page on serpentine soil ( says it exists on the eastern slope of the Appalachians, not all that close to us. The things you learn at the prompting of other bloggers . . . I can’t imagine thousands of pitcher plants. I’ve only seen them in greenhouses and botanical gardens, a few at a time.
