I went back to Carondelet Park to look at the sinkholes that dot the landscape. Much of park has these undulating pockets and depressions, which are the remnants of karst topography.
I strongly suspect that the ponds were adapted from the sinkholes, plugged and converted by the park designers for recreation. I would imagine much of the design is based off of the sinkholes, including the roads.
I also came upon a fox, resting in the grass near the woods.
I am giving a lecture on the Flemish Baroque painter Jacob Jordaens tomorrow Thursday, November 15, 2018 at 11:00 AM, and reprised at 6:00 PM on Friday November 16, 2018 at the Saint Louis Art Museum.
