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. [1] [2] The Des Plaines crater is 5.5 miles (8.9 km) in diameter and covers an area of approximately 25 square miles (65 km ...
This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth. For eroded or buried craters, the stated diameter typically refers to an estimate of original rim diameter, and may not correspond to present surface ...
As of 2016, only two of the structures, Crooked Creek (320 ± 80 Ma) and Decaturville (< 300 Ma), both in Missouri, are listed as confirmed impact craters in the Earth Impact Database. [3] There is evidence that at least some of the features, such as Hicks Dome in Illinois, are volcanic in origin. These features are associated with faults and ...
The Glasford crater was discovered by the Central Illinois Light Company (formerly CILCO, now Ameren) while drilling wells for underground natural gas storage. [10] [11] It is not visible from the surface, as it is covered by agricultural farmland. [12] [11] The present day location is near the intersection of Cowser and Kingston Mines roads. [9]
If the team can determine the site is a crater formed by an ancient impact event, then the next step is researching just when it happened. Of the world’s roughly 200 impact craters, 31 are ...
Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2]
