July 31, 1984: "Melissa Carlson, a staff member of the Detroit ranger station, said Phil Willet, the U.S. Forest Service's lead carpenter, e\expects the work to be completed by mid-August so the new lookout will be in service during most of the high risk fire season. Lookout Mike Rountree is using a temporary canopy shelter to protect the Osborne fire-finder sighting instrument and map which used to locate smoke spotted in the forest. A pack train from the Forest Service's Fish Lake Guard Station took in additional supplies Monday, Carlson said. The new structure will replace one that has been atop the mountain for about 50 years. The existing lookout was built in the 1930's by the Civilian Conservation Corps. Continued exposure to harsh weather at the 5,771-foot elevation has caused extensive deterioration. For awhile, the lookout was abandoned, and its windows were removed. It was remodeled during the late 1970's and early 1980's, but its condition is not satisfactory for use, Carlson said. The new structure will be a typical square building with a catwalk around the outside and large windows on all four sides. Some type of lookout has been atop Coffin Mountain since the first decade of this century, Carlson said. The earliest was a pole construction and was built between 1905 and 1910, when the only transportation was by pack animals. Now there is a road to within a mile and a half of the summit. Some supplies still are taken up each year by mule train, but most of the construction materials for the new lookout were airlifted by helicopter in mid-June, Carlson said." (The Register-Guard)
