T. Lee observed a dip to the northeast of 11°. In the Juniper Hills near Juniper post-office he noted a dip of 3° N. in the Redwall limestone. 46445°— Bull. 435—10 5 Digitized by Google 66 RECONNAISSANCE IN NEW MEXICO AND ABIZONA. The Aubrey Valley is due to the red beds of the Supai formation, which extend to the railroad at the Yampai divide. Just west of this place there is a hill of Redwall limestone 200 feet high; which indicates a relatively steep rise of the strata locally. An easterly d...ip of 5° or more is indicated by the relations of the Supai formation and Redwall limestone in outcrops west of Seligman and in the boring at Seligman. In Chino Valley south of Seligman the sandstone at the base of the Ton to lies on granite at an altitude of 6,000 feet; and the well at Seligman, 1,479 feet deep, which ended near the bottom of the Red- wall limestone at an altitude of 3,620 feet, indicates that the base of the Tonto group is here about 2,700 feet above sea level. This would require a dip to the north of 2,300 feet in.
