Outstanding among interesting features of the Jackson Lake Lodge at Moran, Wyoming, are reinforced concrete exterior walls which resemble wood. Plywood panels used as sheathing were steel-brushed to accent the natural pattern in the wood, creating the sculptured surface effect. The finished concrete was cleaned and stained with brown acid stain to give a rustic appearance. Patterns of vertical and horizontal lines in the concrete also help to create the illusion of wood construction. Because of the volcanic ash in the subsoil, piers were used for foundations. Holes were drilled to a depth of 30 feet with a 24 inch diameter auger and filled with concrete. Lightweight concrete joists, prefabricated in Salt Lake City and brought by truck to the site, were used in floor and roof systems. Corrugated metal forms over the joists supported the mesh-reinforced concrete slabs. This type of construction was chosen to save time in erection where so short a working season prevailed.
