Prefabricated by the Weyerhaeuser Sales Company in 1950, Pig Iron Lookout is probably one of a kind. No other examples of this kit have been identified. Similar to an L-4, the 10' x 10' cab has 3' x 3' solid pane windows and a catwalk atop a 10' wooden tower. This Umpqua National Forest lookout, located a half mile below the summit to get a better view, has been restored and it is used as an emergency detection site.

Former lookout Gary Wilson has contributed the following information: "I manned this lookout in the summer of 1951. At that time I believe it was an L4 type cab. The usual paned windows were present and the shutter assembly opened up for shading. It was a brand new lookout which allowed me to do some painting and trimming of Douglas Fir trees felled to improve the view. In 2001 or so I visited the site and found the cab to look similar to the photo. There may have been a lookout structure at site before the current structure. A friend of mine served as a lookout the previous summer living in a tent near the site with an Osborne situated outside on a large log. He joked that he wore out his shoes on one side due to the steep slope he was working on. The current structure was built during this time and into the Fall of 1950."
