The name Glenwood was first used for this locale around 1880. Glenwood post office was established in 1886, though it was not always in the same location. In the 1920s, the Gales Creek and Wilson River Railroad had a terminal station there named Aagard after Olaf Aagard, owner of the Aagard Lumber Company. The name of the station was soon changed to Glenwood to match the post office.
Glenwood is located South East of Mt. Adams in Washington State, in a small valley, 13 miles below its timberline. Glenwood hosts the annual Ketcham Kalf Rodeo during Father’s Day weekend. Close to Mount Adams, Glenwood has gorgeous aspen stands, rivers, and lakes, and a small town feels.
