A number of the cliff dwellers must have gone into northern Arizona to join the friendly Hopi, with whom they had long established trade relations. Modern Hopi traditions still indicate some ancestral origins in the Verde Valley. _Montezuma Well_ Another example of prehistoric Indian work can be seen at Montezuma Well, a detached part of Montezuma Castle National Monument, 7 miles by road northeast of the Castle. This area contains a large limestone sink, half filled with water which continually flows out at the rate of 1,500,000 gallons a day. The Indians, who constructed their small cliff dwellings and pueblos around this well, diverted the water into irrigation ditches which carried it to their farmlands below. These ditches are visible today because they were cemented up by the lime content of the water which flowed through them. The story of the Indians at Montezuma Well is similar to that at Montezuma Castle. _How To Reach the Monument_ Montezuma Castle is 5 miles north of Camp Verde, 60 miles south of Flagstaff, and 65 miles east of Prescott. It may be reached by U. S. 89 Alternate from Flagstaff via Oak Creek Canyon and Sedona, or by the same highway from Prescott through Jerome, Clarkdale, and Cottonwood, then on a State road through Cornville. It may also be reached by State Routes 69 and 79 from Phoenix, 95 miles to the south. Another approach from the south is the graveled road from Roosevelt Dam, via Payson, Pine, and Camp Verde. _About Your Visit_ You will find small museums at both Montezuma Castle and Montezuma Well, to help you understand the area and its history. The monument is open daily from 8 a. m. to 5 p. m. There are very limited picnic facilities in both sections. The nominal admission fee is waived for children under 12 years of age. [Illustration: _Cliff Dwelling at Montezuma Well_] _Mission 66_ Mission 66 is a program designed to be completed by 1966 which will assure the maximum protection of the scenic, scientific, wilderness, and historic resources of the National Park System in such ways and by such means as will make them available for the use and enjoyment of present and future generations. _Administration_ Montezuma Castle National Monument is administered by the National Park Service of the U. S. Department of the Interior. It was established by Presidential proclamation in 1906 and contains 783 acres in 2 sections. A superintendent, whose address is Camp Verde, Ariz., is in immediate charge. [Illustration: U. S. DEPARTMENT OF THE INTERIOR; NATIONAL PARK SERVICE] UNITED STATES DEPARTMENT OF THE INTERIOR Fred A.
