Leafy impressions in concrete

ConcreteLeaves1

During the AMS meeting in Carbondale, Illinois last month, I went on a walk one afternoon and passed by a concrete sidewalk covered with fossil-like impressions of tree leaves.

Some of the marks had bits and pieces of leaves still stuck on them.

Apparently, the concrete had been poured not long ago, perhaps last fall and perhaps on a windy day when leaves were dropping from nearby trees.

They were quite detailed; I could make out the veins and the curvature of the leaves.

The 1st leaf was probably an oak, while the last one looks like a sycamore, I am not sure about the 2nd one.

It's a very attractive look, even if inadvertent.
