Here’s a nice piece of stonework on upper Lakeshore Avenue.
It’s a pit lined with picturesque cobbles and rimmed with gray slate flagstones. A large slate boulder is mounted in the center, and a fountain trickles off a smaller slate stone over the boulder, cascading into the pit with a delightful sound. Thanks for the gift to passers-by.

It’s in the stretch above the three-way split.

Where is this exactly. I live near Lakeshore and often take walks but have never seen this fountain. Very cool site that you have.
