I've been noticing a lot of these leaf images while walking to and from work…..
Usually after an autumn rain or when the ground is especially cool and saturated.
But they're not just watermarks from fallen leaves because they linger on the sidewalk for several days or longer--well after everything is dry again.
The best way to describe them is the residue of each leaf mixes with the wetness underneath it, creating a sort of stamped impression on the pavement. Cool!
They remind me of primitive, prehistoric markings.
Now I find myself scanning sidewalks and searching for more.
How many of these "leaf stamps" have you seen lately?
