The Western Open was a professional golf tournament in the United States, for most of its history an event on the PGA Tour. The tournament's founding in 1899 actually pre-dated the start of the Tour, which is generally dated from 1916, the year the PGA of America was founded. The Western Open, organized by the Western Golf Association, was first played in September 1899 at the Glen View Club in Golf, Illinois the week preceding the U.S. Open. At the time of its final edition in 2006, it was the third-oldest active PGA Tour tournament, after The Open (1860) and U.S. Open (1895). The tournament was held a total of 103 times over the course of 108 years. The event was not held in 1900, 1918 (World War I), and 1943–45 (World War II). Players from the U.S. won the tournament 77 times, followed by Scotland with fifteen wins. Walter Hagen had the most victories with five, and seventeen others won the event at least twice. The champions' list includes two amateurs: Chick Evans in 1910 and Scott Verplank in 1985. Beginning in 2007, the Western Open was renamed the BMW Championship, the penultimate event of the FedEx Cup playoff series. Played with the PGA Tour's point system as the sole qualification standard, it is no longer open to amateurs. Title sponsorship was introduced in 1987, and included Beatrice, Centel, Sprint, Motorola, Advil, Golf Digest, and Cialis.

The Chicago Area Waterway System (CAWS) is a complex of natural and artificial waterways extending through much of the Chicago metropolitan area, covering approximately 87 miles altogether. It straddles the Chicago Portage and is the sole navigable inland link between the Great Lakes and the Mississippi River and makes up the northern end of the Illinois Waterway.The CAWS includes various branches of the Chicago and Calumet Rivers, as well as other channels such as the North Shore Channel, Cal-Sag Channel, and Chicago Sanitary & Ship Canal. The CAWS ends near the Lockport Navigational Pool, the highest elevated of the eight pools of the Illinois Waterway. There are three major locks within the CAWS, operated by the Army Corps of Engineers: the Chicago Harbor Lock, the Lockport Lock & Dam, and the T.J. O'Brien Lock and Dam.Artificial waterways connecting the Mississippi and Great Lakes systems via the Chicago area, over the Chicago Portage, began with the I&M Canal in 1848. The CAWS as it exists today began to take shape in 1900, with the construction of the Chicago Sanitary & Ship Canal to reverse the flow of the Chicago River (and eventually the Calumet River), which previously flowed into Lake Michigan, so as to instead flow toward the Mississippi River, thus carrying sewage away from the City of Chicago. Thereafter, additional artificial waterways were built that became part of the CAWS, such as the North Shore Channel, which runs inland from Wilmette to the Chicago River and was constructed in 1910, and the Cal Sag Channel, which provides a direct path from the Calumet River to the Illinois Waterway and was finished in 1922.In the 21st century, a focus of concern around the CAWS has been its potential role as a corridor for Asian carp to enter Lake Michigan. Suits in district court and before the United States Supreme Court have been unable to obtain an injunction requiring the connection between the CAWS and the Mississippi drainage to be closed.

The Forge: Lemont Quarries Adventure Park is an adventure park that opened July 17, 2020 in Lemont, Illinois, a suburb of Chicago. It is a public-private partnership with the Village of Lemont and Lemont Township.Covering approximately 300 acres (120 ha), it features ziplines, ropes courses, climbing towers and walls, bouldering areas, fishing, paddleboating, kayaking, mountain biking and hiking trails and other outdoor activities. The ropes course will be the tallest in North America, at over 120 ft (37 m). It also has adventure dining, a beer garden, an event venue, and summer camps.The park was built on disused industrial land and flooded former Lemont yellow dolomite quarries straddling the Illinois and Michigan Canal National Heritage Area, and abutting the Chicago Sanitary and Ship Canal. It is named after the Forge Quarry and uses it, the Great Lakes Quarries, and the I&M Canal as water features. It was originally scheduled to open on May 25, with a grand opening scheduled for June 27, 2020, but due to the COVID-19 pandemic this was pushed back to July 2020.

The Track Imaging Cherenkov Experiment (TrICE) is a ground-based cosmic ray telescope located at Argonne National Laboratory near Chicago, IL. The telescope, which contains a Fresnel lens, eight spherical mirrors, and a camera with 16 multianode photomultiplier tubes, uses the atmospheric Cherenkov imaging technique to detect Cherenkov radiation produced when cosmic rays interact with particles in the Earth's atmosphere. The telescope is primarily a research and development tool for improving photomultiplier tube cameras and electronic systems for future gamma and cosmic ray telescopes. It is also used to study the energy and composition of cosmic rays in the TeV–PeV range, and the collaboration is currently conducting pioneering work in detecting direct Cherenkov signals from cosmic rays.

Sag Bridge, Illinois is an Unincorporated community in Lemont Township in southwestern Cook County, Illinois, United States. Sag Bridge is an important waterway junction between the Calumet Sag Channel and the Chicago Sanitary and Ship Canal. It is also the junction of IL 83 (Kingery Highway) and IL 171 (Archer Avenue) which meet at Sag Bridge to cross the Calumet Sag Channel together on the eponymous bridge. The community was named for a predecessor of the present bridge. It is within the village limits and postal delivery zone of Lemont, Illinois. Other than the bridge for which it was named and the canal that the bridge crosses, the most significant feature of the community is the historic St. James at Sag Bridge Catholic Church, listed on the National Register of Historic Places.

Now the NBL Program Office, the New Brunswick Laboratory (NBL), was a United States government-owned and operated, center of excellence in the measurement science of nuclear materials. It was established in 1949 by the Atomic Energy Commission and was located in New Brunswick, New Jersey. It was relocated between 1975 and 1977 and was located, as a Federal enclave, on the site of Argonne National Laboratory, about 40 kilometers (25 miles) southwest of Chicago, Illinois. NBL was part the Department of Energy's Office of Science Chicago Office.NBL is the U.S. Government's Nuclear Materials Measurements and Reference Materials Laboratory and the National Certifying Authority for nuclear reference materials and measurement calibration standards. As an internationally recognized Federal laboratory, NBL provides reference materials, measurement and interlaboratory measurement evaluation services, and technical expertise for evaluating measurement methods and safeguards measures in use at other facilities for a variety of Federal program sponsors and customers. NBL functions as a Network Laboratory for the International Atomic Energy Agency (IAEA). NBL was reorganized into the NBL Program Office in 2016, and its nuclear reference materials were transferred to a new distribution center located near Oak Ridge, Tennessee. It is part of the National Nuclear Security Administration's Office of Defense Programs.

Chicago Pile-5 (CP-5) was the last of the line of Chicago Pile research reactors which started with CP-1 in 1942. The first reactor built on the Argonne National Laboratory campus in DuPage county, it operated from 1954-1979.CP-5 was a thermal-neutron reactor using enriched uranium as fuel and heavy water as coolant and as a neutron moderator. It produced neutrons for use in research. The reactor had an output rating of 5 megawatts.Cleanup and decommissioning of the site of CP-5 was started in 1991 completed in 2000. The cleanup process included removal of all contaminated equipment and spent fuel, decontamination of the reactor vessel and associated plumbing, and removal of the spent fuel pool, reactor internals and the hot cell liner. The accessible areas of the structure have been certified as having radiation levels equivalent to background radiation.

The Chicago Sanitary and Ship Canal, historically known as the Chicago Drainage Canal, is a 28-mile-long (45 km) canal system that connects the Chicago River to the Des Plaines River. It reverses the direction of the Main Stem and the South Branch of the Chicago River, which now flows out of Lake Michigan rather than into it. The related Calumet-Saganashkee Channel does the same for the Calumet River a short distance to the south, joining the Chicago canal about halfway along its route to the Des Plaines. The two provide the only navigation for ships between the Great Lakes Waterway and the Mississippi River system. The canal was in part built as a sewage treatment scheme. Prior to its opening in 1900, sewage from the city of Chicago was dumped into the Chicago River and flowed into Lake Michigan. The city's drinking water supply was (and remains) located offshore, and there were fears that the sewage could reach the intake and cause serious disease outbreaks. Since the sewer systems were already flowing into the river, the decision was made to reverse the flow of the river, thereby sending all the sewage inland where it could be diluted before emptying it into the Des Plaines. Another goal of the construction was to replace the shallow and narrow Illinois and Michigan Canal (I&M), which had originally connected Lake Michigan with the Mississippi starting in 1848. As part of the construction of the new canal, the entire route was built to allow much larger ships to navigate it. It is 202 feet (62 m) wide and 24 feet (7.3 m) deep, over three times the size of the I&M. The I&M became a secondary route with the new canal's opening and was shut down entirely with the creation of the Illinois Waterway network in 1933. The building of the Chicago canal served as intensive and practical training for engineers who later built the Panama Canal. The canal is operated by the Metropolitan Water Reclamation District of Greater Chicago. In 1999, the system was named a Civil Engineering Monument of the Millennium by the American Society of Civil Engineers (ASCE). The Canal was listed on the National Register of Historic Places on December 20, 2011.
