The grounds of Pleasant Home sit on the St. Lawrence Seaway Divide; one of the minor divide which separated rainwater between the Mississippi River and Lake Michigan. In 1892, when the flow of the Chicago River was reversed to create a disease-free water supply for the City of Chicago, the divide ceased to function. This remarkable engineering feat took over 18 years and $6.5 million dollars to undo millions of years of geologic growth.
As a way to elucidate this shifting geological history, a single line of bricks marked the Continental Divide. The bricks, which emulate the Roman brick chosen by the architect George W. Maher, are made of ice and clay. As the ice melts, a demarcation remains.
