This bit of lakefront, once a seasonal settlement for the Pottawatomie, was left alone due to an umovable and deeply embedded bedrock of granite, which defied the development techniques of the time. It is the only natural beach frontage left and virtually unknown on the entire Chicago coastline. This beachfront and the massive outcrop of the Southworks table slag to the south and the water treatment plant to the north is a perfect demonstration of the vigorous advancement of the steel industry and 20th-century development.
