    Mount Joliet

    "A few miles from Joliet, we passed an object, to me of great interest--it was an Indian mound. This was a perfect gem--as regular, as smooth, and as green as if cut out of an emerald--being an oblong of fifty rods high, and seventy or eighty long. Although centuries have passed since it was formed, it is as perfect in shape, as if just moulded. A beautiful, solitary thing it is, telling of nations and events now lost in the mists of time."

    Mount Joliet had been a well known landmark since Joliet himself recorded it on his 1674 map. It wasn’t until the late Nineteenth Century, when it was quarried, that it proved to have been a purely geological feature and not an “Indian mound.”

    Mount Joliet was located on the eastern half of the dividing line between the northeast and southeastern quarters of Section 19, Joliet TWP. Southwest of town on the north bank of the Des Plaines River.
