Des Plaines Disturbance 01

The Des Plaines crater or Des Plaines disturbance is recognized as an impact crater in Cook County, Illinois, United States. It is located beneath the eastern part of the city of Des Plaines, which is a suburb of Chicago.The Des Plaines crater is 5.5 miles (8.9 km) in diameter and covers an area of approximately 25 square miles (65 km2). The age of the crater is unknown but is thought to be between 280 million years and 2 million years (Permian or younger). The crater is buried beneath 75 to 200 feet (23–60 m) of glacial till and can only be seen as a series of faults and deformations in well logs and seismic surveys. Faulting in the structure has produced as much as 600 feet (180 m) of vertical displacement. Subsurface strata of Cambrian through Pennsylvanian age has been faulted and tilted by the event. The anomalous area was first noted by water well drillers in 1893, who noted an absence of water in a 1,600-foot (490 m) deep well. Prior to being recognized as an impact structure, the feature was referred to as a cryptoexplosion structure or cryptovolcanic structure, as were several others in the Midwestern United States. The upfaulted central portion and the presence of shatter cone structures support the impact origin.

WMTH

WMTH-FM, located in Park Ridge, Illinois, was among the first FM high school radio stations in the United States when it was licensed in 1959. Established by the Student Council at Maine Township High School, now Maine East High School, the station went on the air during December 1959. The station became known as "The Voice of Maine Township". The radio station was built by electronics teacher, Theron Whitfield, and electronics students in the school. WMTH-FM has studios at all three existing Maine Township High Schools; Maine West High School in Des Plaines and Maine East High School and Maine South High School in Park Ridge. There was also a studio at the former Maine North High School in Des Plaines. The call letters were chosen "MTH" as in Maine Township High (school). The WMTH-FM antenna is located on the highest point of the school building at Dempster and Potter Roads in Park Ridge. The studio from 1959 through 1970 was located in room 147B, across the hall from the auditorium. When the center courtyard building opened in the fall of 1970, the radio station relocated and the first WMTH-TV television studio was built. The original power of the station was 16 watts effective radiated power at a frequency of 88.5 MHz. This continued from 1960 until 1983 when the frequency was changed to 90.5 MHz and the power reduced to 10 watts. This leaves it as one of the lowest powered FM stations in the United States, and one of few remaining under the now-discontinued Class D license. WMTH-TV is another section of WMTH, they broadcast a mixture of music, school sports events, and other programs of local interest. All of the broadcast events are streamed on their respective youtube channels. In addition, all events broadcast are staffed by WMTH Club Members and the broadcasts are in care of their respective instructors.

McDonald's No. 1 Store Museum
McDonald's No. 1 Store Museum

The McDonald's #1 Store Museum was housed in a replica of the former McDonald's restaurant in Des Plaines, Illinois, opened by Ray Kroc in April 1955. The company usually refers to this as The Original McDonald's, although it is not the first McDonald's restaurant but the ninth; the first was opened by Richard and Maurice McDonald in San Bernardino, California in 1940, while the oldest McDonald's still in operation is the third one built, in Downey, California, which opened in 1953. However, the Des Plaines restaurant marked the beginning of future CEO Kroc's involvement with the firm. It opened under the aegis of his franchising company McDonald's Systems, Inc., which became McDonald's Corporation after Kroc purchased the McDonald brothers' stake in the firm. The actual restaurant was demolished in 1984, but McDonald's realized it had a history to preserve, so it built a replica. With gold arches placed over a glass and metal, red-and-white tiled exterior, the building largely followed the McDonald brothers' original blueprints, which they had introduced when they began franchising in 1953. A Phoenix, Arizona, restaurant was the first built in this manner. Kroc's restaurant was the first McDonald's built in a colder climate, and some adaptations were made to the design, including a basement and a furnace. McDonald's announced that the building would be torn down as early as the end of 2017 due to repeated flooding of the site. The completed demolition ended in mid 2018. McDonald's then decided to donate the land to the city for a grassy park area.The entrance sign was original, with early cartoon mascot "Speedee," representing the innovative Speedee Service System, inspired by assembly-line production which the McDonald brothers had introduced in 1948. It was, however, moved from its original location at the south end of the property. The sign boasted "We have sold over 1 million." The replica museum offered irregular summer hours and was often closed; tours were by appointment. The ground floor exhibited original fry vats, milkshake Multimixers (which Kroc had been selling when he first encountered the San Bernardino McDonald's restaurant), soda barrels, and grills, all attended to by a crew of male mannequins in 1950s uniforms. Visitors could walk in through the kitchen or look through the order windows in front (there was no sit-down restaurant section in the 1955 design). In the basement was a collection of vintage ads, photos, and a video about McDonald's history. Upon demolition, various equipment was relocated to McDonald's corporate headquarters in downtown Chicago as well as its R&D facility in the southwest Chicago suburbs. In the 1980s, a new, modern McDonald's was built across the street and to the south, replacing a Howard Johnson's restaurant (then Ground Round). At this McDonald's there are a half dozen glass-enclosed exhibits featuring McDonald's historical artifacts arrayed around the eating tables. Included are red and white tiles from the original restaurant and string ties worn by employees from the 1950s to the early 1970s. A blueprint for the original "Speedee" electrical sign appears on one wall. The Big Mac Museum Restaurant, another McDonald's museum, opened on August 23, 2007, in Irwin, Pennsylvania, on Route 30 Lincoln Hwy. A museum also exists at the Original McDonald's site in San Bernardino on U.S. Route 66 in California. It is a reconstruction operated by the owner of the Juan Pollo chain and is not affiliated with McDonald's Corporation.

Des Plaines River Trail
Des Plaines River Trail

The Des Plaines River Trail is a recreational multiuse trail that follows the course of the Des Plaines River through most of Lake and part of Cook County in northeast Illinois in the United States. Trail uses include hiking/walking, bicycling, equestrian, and even winter cross country skiing and snowmobiling (conditions permitting). Since much of the trail lies in the flood plain along the Des Plaines River, sections of the trail are occasionally closed due to flooding during periods of heavy rain. Though not all sections of the trail connect directly, there is a section more than 31 miles (50km) long running through Lake County starting at Russell Road along the Wisconsin/Illinois state line and running south into Cook County. There are additional disconnected sections south of the town of Des Plaines.Much of the Des Plaines River Trail runs through a protected corridor made up of a series of public lands that are part of the Lake County Forest Preserve District and the Cook County Forest Preserve District]. The numerous forest preserves provide additional recreational opportunities along the trail. Underpasses and bridges are used to facilitate many (not all) of the major road crossings (The underpasses are highly prone to flooding during the spring). Cook County Forest Preserve rangers give lectures at various time during the year. There is a nature house where forest animals reside for the public to view. The trails are very calm and beautiful and especially in the fall when the leaves change colors. A peak time to walk the trails is the second or third week in October. You can picnic right next to the Des Plaines River.
