This is an anticline exposed on Mc Leod Street, southwest of Hot Springs, Garland County, Arkansas. It’s not unique as, anticlines are common in the Ouachita’s and other mountain ranges throughout the world. Most often though, these structures are large scale and cover expanses of land that can’t be viewed from a human vantage point. When they do form on a scale that’s small enough for human observation, we typically don’t have the benefit of a freshly blasted exposure like this one.
In fact, many times geologists must infer that folds like this exist in places deep underground that no one has or will ever see. That’s why, if you see a geologist on the side of the road, taking something like this in, as in the picture above, just let him have his little moment. The exposure is of deep marine sedimentary deposits of the Stanley Formation.
