“ Erosion is still going on slowly and persistently among the great pillared cliffs of the monument. Some of the most exposed portions have already been worn away. 2 Pedestal or balanced rocks have formed and fallen; others are tottering; more are just taking shape. Within the span of a human life, only minor changes may be noticed, but with the passage of the centuries the face of Nature is ever changing. ”

“ There is a campground in Bonita Canyon, one-half mile above monument headquarters, at 5,340 feet elevation. Drinking water, fireplaces, wood, and picnic tables at 30 campsites; restrooms, showers, and laundry room are centrally located. Campers may heat water for showers or laundry in a wood-burning 4 waterheater. Although the campground is open all year, shower rooms may be closed during freezing weather. ”

“ Living mainly on wild animals and native plants, these resourceful people moved from place to place depending upon the requirements of the season and the supply of food. Occasionally they raided the farmer Indians of the desert valleys, and with the coming of the Spaniards, they found increased incentive to pillage the European cattle, horses, and grains introduced by the white men.
Stolen horses greatly increased the power and widened the range of Indian activities, and the southeastern corner of what is now Arizona became an Apache stronghold. ”
