Flotsam. mud on surface of slowly circulating water. Looks like it's under effects of the same forces that form the Saturn's circles.
Seems I rationalized buying some fancy Ilford film for documenting some class projects. Photography was another attempt to push the envelope, like when I turned in a thermal-printed paper ribbon generated by a calculator program I wrote to solve some homework problems. The teaching assistant gazed into the distance for a moment and said something thoughtful about how someday everyone would do their work that way.
This project was a lab that all mechanical engineering students had to do. I believe we adjusted a cone at the end of the duct, measured air pressure differences (and hence air flow) at various points inside the duct, and documented the results in a paper. Typing centered equations with a manual typewriter was not for the faint of heart.
Although I was using the same sturdy Nikon F, I don't think I owned a flash then. I must have relied on a combination of fast film and a relatively slow exposure, to work under fluorescent light in the basement of the mechanical engineering building.

Named after Benjamin Franklin who studied surface tension in the 18th century. He might have enjoyed this image. Ink moves fast in outflows from central bubbles; taking up a dramatic shape with scalloped edges.
This view looks downstream in Winter Camp Wash, toward the area from which I have come. After parking at the Delicate Arch Trailhead, I walked along the park road to the wash, then walked up the wash to this point. Light brush here and there made the walking interesting. Later I encountered brush so thick it was impassable. That forced me to scramble out of the wash to by-pass the brush. There were signs of recent flooding throughout the wash: there is flood debris draped over a branch next to me.
The tilted plateau in the background at right is the location of the trail that leads to Delicate Arch. The last portion of this circumnavigation was on that trail. My photos on PBase include complete coverage of the circumnavigation.
Joe Tripod got sandy feet from helping with this picture. He didn't complain.

the huge ripples caused by Ice Age floods.
