As everybody knows, the highest point on which a person can stand in Chicago is Willis Tower’s Skydeck, which, at 1,353 feet up, offers a view of Michigan, on the other side of the lake. But where is the highest natural point in the city?

According to “A History of Beverly Hills, Chicago,” a 1926 University of Chicago thesis by Cora DeGrass Heinemann, that Far South Side neighborhood, which now goes by Beverly, “is the highest land in Cook County.” That’s because the Blue Island Ridge, a glacial moraine, winds through it.

In the Dan Ryan Woods, a forest preserve that adjoins Beverly to the north, a historical marker for Lookout Point says the spot was “used as a signal station on [the] main highway of Indian travel.” Lookout Point offers a fine view of downtown Chicago, but at 660 feet above sea level, it’s not quite the highest spot in the city. That’s a little farther south, at 91st Street between Claremont and Western, where the land rises to 670 feet.

By contrast, the city’s lowest point, the lakefront, is at 577 feet. The lesson here: With less than 100 feet between its highest and lowest elevations, Chicago is one flat city. Still, even a flat city has its peaks.
