The trail of the summer vacationist has deviated during the last decade from the old familiar courses to embrace vast areas in Wyoming and Montana. A veritable invasion of eastern tourists, known in the parlance of men of the range as "dudes", has followed the opening up by modern transportation of this beautiful country.

Located in the mountainous regions of these two far western States, on the last frontier, are the dude ranches, in the mouths of canyons, among foothills, or in clearings in the forest. These ranches are not pretentious places, but are rustic and unique. Their popularity began in 1904, when Howard, Willis, and Alden Eaton established the now famous Eaton Brothers' "Dude Ranch" at Wolf, Wyo.

Many of these ranches are situated in territory within easy access to the Grand Teton Park. A complete list may be obtained by addressing the Dude Ranchers' Association, Billings, Mont.
