One of the most important watering places of northeastern Arizona is LeRoux Spring, seven miles northwest of Flagstaff on the southwestern slope of the San Francisco Mountains. This never-failing spring was a welcome spot to the pioneers who traveled the rocky road along the 35th parallel of latitude. San Francisco Spring (or Old Town Spring) at the present Flagstaff, was much less dependable and at the time of the construction of the Atlantic & Pacific railroad in 1881-2, water often was hauled to Flagstaff from the larger spring, at times sold for $1 a barrel. The importance of this water supply appears to have been appreciated early by the long-headed directing body of the Mormon Church. Early in 1877, under direction of John W. Young, son and one of the counselors of Brigham Young, from the Little Colorado settlements of St. Joseph and Sunset, was sent an expedition, that included Alma Iverson, John L. Blythe and Jos. W. McMurrin, the last at this writing president of the California Mission of the Church, then a boy of 18. According to Ammon M. Tenney, this LeRoux spring was known to the people of the Little Colorado settlements as San Francisco spring. Mr. McMurrin personally states his remembrance that the expedition proceeded along the Beale trail to the spring, near which was built a small log cabin, designed to give a degree of title to the water and to the locality, probably also to serve as a shelter for any missionary parties that might travel the road. There is no information that it was used later for any purpose. The men were instructed to build a cabin at Turkey Tanks, on the road to the Peaks, this cabin to be lined with pine needles and to be used as a storage icehouse, Counselor Young expressing the opinion that there would be times in the summer heat of the Little Colorado Valley when ice would be of the greatest value. The tanks were hardly suitable for this purpose, however, and the icehouse was not built. Location of the LeRoux spring by the Iverson-Blythe party in 1877 appears to have been sufficient to hold the ground till it was needed, in 1881, by John W. Young, in connection with his railroad work. About sixty graders and tie cutters were camped, mainly in tents, on LeRoux Prairie or Flat, below the spring, according to Mrs. W. J. Murphy, now of Phoenix, a resident of the Prairie for five months of 1881, her husband a contractor on the new railroad. She remembers no cattle, though deer and antelope were abundant.
