The other day I found this along the railroad tracks.
The formation is not raised, it is somewhat recessed so I do not think it is any type of insect crusties.
I did scrub the rock with a nylon brush and nothing came off so I think it is very old.
Any ideas?
Could this have been meant for me (Letter M for Matmit?)
