September 5, 1926: "Plans are being made by the national forest service to build a lookout house or tower before next fire season on one of three points in the Cascade forest, according to Nelson F.

August 1, 1928: "One piece of concrete work which owners may be sure will not have too much water in it for the amount of cement, gravel and sand is being done in the Cascade national forest. Work will start today on packing lumber for a lookout house to be built at the top of Indian Ridge in the forest. The lumber has been cut to size at McKenzie Bridge by Mason Warner. Dee Wright and Ed Woods are to pack materials to the top if the ridge, about 12 miles. All materials for the house must be packed in, including the water for mixing the concrete for foundation. That's why water will probably not be wasted in mixing process. The water is being packed in 10 gallon casks. Forest officials hope to finish the building this year. A carpenter will probably help frame it and the lookout will finish it." (Morning Register)
