Open wood platforms on towers were constructed on Pratt Mountain prior to the 1934 steel tower construction.

Although Merritt B. Pratt, reported as early as 1930 that plans were in process to erect a steel tower at the "Pratt Lookout," the facilities were not constructed until 1934. The 45 foot tower is an Aermotor Company product and the residence is the Forest Service's BC-201 design. The CCCs built both buildings.

During the 1950s, CDF remodeled the tower's cab (adding a catwalk and door, and replacing the original windows with aluminum frame, 1/ 1 sliders). The house has undergone several revisions. The front porch has been enclosed and converted to a bathroom. A metal, front door has been installed. Asbestos tiles and asphalt composition roofing have been added. The bedroom windows and walls have been replaced (with non-original type materials). However, the kitchen's interior paneling, windows and doors are original. The station was named in honor of State Forester Pratt.

The lookout is located upon the broad summit of Mail Ridge. Vegetation is oak woodland, with some pine mix. There are numerous radio vaults and towers on the ridge. A 10,000 gallon, concrete water storage tank and small garage (built in 1950) are near the lookout residence. The site is not open to the public, being about 2.2 miles from the nearest paved road.

The steel tower was dismantled some time before 2011. The cab and 14 feet of tower remain as a unit laid on it's side at the original location. The mountain is privately held and continues as a communications site.
