Area codes 708 and 464 are telephone area codes in the North American Numbering Plan (NANP) for the southern and western suburbs of Chicago in the U.S. state of Illinois. The numbering plan area comprises most of western and southern Cook County, and eastern and southern Will County. Area code 708 was created on November 11, 1989, in a split of area code 312. It once served almost all of Chicago's suburbs in Illinois. In 1996, its numbering plan area was reduced in a three-way area code split. The northern suburbs received area code 847, while the western suburbs were assigned area code 630. Area code 708 was Illinois' first new area code since 309 had been created in 1957, and the second new code for the state since the announcement of the original North American area codes in 1947, when the state was divided into four numbering plan areas (217, 312, 618, and 815). The Illinois side of the Chicago area–312/773/872, 708/464, 847/224, 630/331, and portions of 815/779–is one of the largest local calling areas in the United States; with few exceptions, no long-distance charges are levied from one portion of the metro area to another.Prior to October 2021, area code 708 had telephone numbers assigned for the central office code 988. In 2020, 988 was designated nationwide as a dialing code for the National Suicide Prevention Lifeline, which created a conflict for exchanges that permit seven-digit dialing. This area code was therefore scheduled to transition to ten-digit dialing by October 24, 2021.On June 30, 1999, area code 464 was reserved for future relief in 708. Implementation was held off for over two decades until it became clear in 2021 that relief would be necessary. Area code 464 went into effect on January 21, 2022.

Sauk Trail Woods are located within the Cook County Forest Preserves in Park Forest and Chicago Heights, Illinois. They are part of the Thorn Creek Trail System. They contain miles of paved bike trails and off-trail dirt paths. Sauk Trail Woods contains Sauk Lake and Thorn Creek. The topography is fairly hilly, featuring ravines and steep, eroded hillsides. The elevation is the highest on the outskirts of the preserve. Then, as one goes into the Thorn Creek River Valley, you descend steep hills and sandy bluffs. There is an abundance of ravines that have been cut by creeks flowing into the valley. Many of the ravines are surprisingly deep near the bottom of the valley. Most of the Sauk Trail Woods Preserve is covered by dense woods, however there are some open prairie areas. In the northwest section of the woods, there is a fairly large marsh, that is surrounded by thick pampas grass and shallow bogs. The woods are located on the Valparaiso Moraine, which accounts for the hilliness of the area. There are many parking lots with pavilions situated throughout the preserve.
