Native building materials are becoming more popular in North Dakota, and each year an increasing amount of construction utilizes native-made brick and locally quarried sandstone. An interesting development in the use of native materials is the rammed-earth building, the walls of which consist of earth tamped until it is hard as rock. A house and garage of this construction erected on the Scoria Lily ranch near Hettinger (_see Tour 9_), because of their unusually low building cost, have attracted wide attention. The use of native boulders as a building material is well illustrated in the Cairn, home of Mr. and Mrs. Clell G. Gannon in Bismarck. Even with these attempts there is no native North Dakota architecture. The schools, farms, grain elevators, and false-front business buildings are common to the entire Midwest. Many of these, although old, do not mellow, but have an air of impermanence, as though intended to serve only until something better came along. A few houses, on the other hand, follow the good, substantial precedent of the older Eastern homes of the country. New buildings which go up represent a variety of forms, a constant flux in ideas. As evinced by buildings ranging from statehouse to filling stations, North Dakota is architecturally in an irresolute frame of mind, striving, willing to try anything suggested, yet unable, to date, to evolve from these many trials a distinctive architectural contribution of its own. RECREATION North Dakota offers many diverse forms of recreation among scenes varying from the spectacle of the fantastically carved Badlands to the severe beauty of the far reaching prairies. The Badlands are probably the best known recreation area of the State. Here the two Roosevelt Regional State Parks have been set aside, and many miles of bridle paths and automobile roads are being built. The strangely colored buttes form one of the most unusual scenic and geologic areas in the United States, and contain endless treasures of petrified wood and fossils of prehistoric plant and animal life. More conventional is the beauty of the wooded Turtle Mountains, where many attractive lakes provide swimming, fishing, and boating. In the woods are countless varieties of wild flowers, and many species of song birds. Of the many lakes in the Turtle Mountains, the largest and best known are Metigoshe in the northwest part of the hills and Upsilon in the east. Here well-equipped resorts have been established for the accommodation of summer visitors.
