Four miles east of the Roosevelt Dam and eighty miles east of Phoenix, Arizona, are two small groups of cliff-dwellings which together form the Tonto National Monument. The southern group occupies a cliff cavern a hundred and twenty-five feet across. The masonry is above the average. The ceilings of the lower rooms are constructed of logs laid length-wise, upon which a layer of fibre serves as the foundation for the four-inch adobe floor of the chamber overhead.
There are hundreds of cliff-dwellings which exceed this in charm and interest, but its nearness to an attraction like the Roosevelt Dam and glimpses of it which the traveller catches as he speeds over the Apache Trail make it invaluable as a tourist exhibit. Thousands who are unable to undertake the long and often arduous journeys by trail to the greater ruins, can here get definite ideas and a hint of the real flavor of prehistoric civilization in America.
