With a population of 170, Monument is one of Oregon's smallest incorporated cities. This community is situated along the banks of the North Fork John Day River in Grant County. The town is situated southwest of La Grande, between Kimberly and Long Creek along Kimberly Long Creek Hwy.
The area surrounding what is now Monument was first settled on in 1852 by Isaac Vilott. During the early dates, the Shahaptin Indians passing through what is now Monument Valley, called it the area "Man-Mint." Incorporated in 1947.
Though the area is considered a desert area, there are many farms (various livestock) and orchards along the river that grow hay and a large variety of fruits. Rocky Mountain elk and mule deer are seen feeding in the local alfalfa fields and hay stacks. Steelhead & trout spawn in the small creeks that feed into the John Day River.
There is also a Monument, Colorado.
