Орегон штатының Даллас қаласының тарихы мен географиясы

Dallas is a city and the county seat of Polk County, Oregon, United States. The population was 16,854 at the 2020 census. Dallas is along Rickreall Creek, about 15 mile (24 km) west of Salem, at an elevation of 325 feet (99 m) above sea level. It is part of the Salem Metropolitan Statistical Area.

Pioneers in the 1840s started the settlement that became known as Dallas on the north side of Rickreall Creek. It was originally named "Cynthian" or "Cynthiana". A 1947 Itemizer Observer article states: "[T]he town was called Cynthiana after Cynthiana, Ky., so named by Mrs. Thos. Lovelady." According to the county historical society in 1987, Mrs. Thomas J. Lovelady named the new settlement after her home town of Cynthiana, Kentucky. Another source claims that Cynthia Ann, wife of early pioneer Jesse Applegate, named the settlement. In 1902, Louis's son George T. Gerlinger organized a group of investors to build related railroad lines in the area. On May 29, 1903, the first train ran from Dallas to Falls City. At the end of June, passenger trains began regularly scheduled, daily trips to and from Dallas and Falls City; the 9 mile (14 km), 40 minute, one way trip cost 35 cents. Willamette Industries was founded in Dallas in 1906. At that time the company name was Willamette Valley Lumber Company. Louis Gerlinger, Sr. was president of the new company and H. L. Pittock, vice president. George T. Gerlinger served as secretary and manager, and F. W. Leadbetter was treasurer. George Cone served as director and mill superintendent. In the early 21st century, this and other local businesses were taken over by others from outside, which eventually affected the local economy. In March 2002, Willamette Industries was officially acquired by Weyerhaeuser Company in a hostile takeover. In early 2009, Weyerhaeuser's Mill formally closed the Dallas operation. Similarly, Gerlinger Carrier Company in Dallas was taken over by Towmotor.

According to the United States Census Bureau, the city has a total area of 4.81 square miles (12 km2), all of it land.
