Some colorful geology on a small scale

with 8 comments

Nothing in Austin is going to compare to the Badlands of South Dakota. Sorry, Austin, that’s just how it is. Still, we have some much smaller geological formations here that warrant a look. One is a long limestone slab that arches up and then out over a creek in my Great Hills neighborhood. Historically, of course, aeons of water flowing through the creek eroded the limestone to create the overhang. The back wall, which I don’t think ever gets direct sunlight, stays rather dark even during the brightest part of the day. When I went there on June 29th, I stood facing the wall and used flash to reveal the colors and patterns of the always damp and sometimes wet stone.

No more than a hundred feet to the right of the formations shown here are the mud dauber wasp tubes some of you may remember from five years ago. Two years after that, I showed something that wasn’t a tuft of hair on the underside of the overhang.

  1. As impressive as the Badlands’ varied and vibrant colors can be, there’s still something about this teal, gray, and pink-tinged brown that I find more appealing. To paraphrase the old saw, the Badlands colors are a nice place to visit, but I wouldn’t want to live with them.

    I certainly do remember those mud dauber tubes. What caught my attention in this photo is an equally interesting detail: the very thin “threads” hanging down. They look to be rock, rather than something built on top of it. In any case, the effect of a fringe is pleasing.

    • It’s comforting to have this overhang so close at hand in my neighborhood. While I’ve visited it plenty of times over the years, not till recently, thanks to flash, did I truly appreciate the intricacy and colors of the formations on that back wall. The vertical “threads” you noticed have been built up over long periods as water dripping down the wall has deposited minerals. I imagine that after one of these flowstone formations gets started, it keeps future drops of water moving along the same path, thereby leading to further deposition of minerals. Parts of the back wall are also often covered with spiderwebs. None seem to be visible in this picture, but they’re quite noticeable in some of the other photographs I took.

  2. Beautiful colours. When will you present geology in miniature scale?

    • That’s a good suggestion. I could go back with a macro lens and a ring flash to take close images of the patterns in these formations. I wonder if they might come out looking like hills and valleys.

  3. Very cool image! I think a macro series of this would be cool! Look forward to seeing it! It also looks like a NASA image from space.

    • I did take other pictures of that wall, though not with a macro lens. The place is in my neighborhood, so I can go back and try it one of these days. While this blog probably isn’t the right outlet for such abstract images, I appreciate your suggesting the idea and your enthusiasm about it.
