Monitor

Before the existence of Monitor, the area was known by settlers as Brown's Flat, named after Reuben Brown who settled there in 1885. At the site of Monitor a school was built to serve school districts on both sides of the Wenatchee River.

The Great Northern Railway passed through in 1892, causing little stir in the area but jump-starting the construction of the Peshastin irrigation ditch, which would bring water the area and make it a prime place for agriculture. 

Monitor emerged as an agricultural shipping point along the railroad and a small community grew around the warehouses. A post office was established in 1902 and the citizens chose to rename the community in honor of the Ironclad warship USS Monitor. The town currently has a post office and several small businesses located along U.S. 2 which now bypasses Old Monitor on the north side of the Wenatchee River.
