[Mile-marker 7]
Throughout most of its 6-mile length the Redlands fault is a vertical or
nearly vertical normal fault, but along and near this 0.7-mile stretch
it is a reverse fault that dips from 45° to 60° to the southwest, as
shown in figure 40 and in the cross section of figure 8. Good views of
the fault are seen all along the fence, but especially at points
one-tenth and four-tenths of a mile northwest of the first turn, the
second of which is shown in figure 40. Just after turning north on South
Broadway, let us turn west a few hundred feet on paved Wingate Drive to
see the northwest end of the Redlands fault, which passes through a col
to the left of updragged remnants of the thinned red Chinle Formation
and the Wingate Sandstone, as shown in figure 41.
[Illustration: REVERSE PART OF REDLANDS FAULT, looking N. 65° W.
from point on South Broadway along boundary fence. Most of Chinle
Formation has been squeezed out, but lower part of Wingate Sandstone
may be seen dipping about 45° southwestward beneath dark Proterozoic
rocks. Next pink band to right is Entrada Sandstone. Jumbled mass of
white sandstone slabs at right of photograph is part of Salt Wash
Member of Morrison Formation and is known locally as “White Rock”.

Canyon monocline in next canyon to northwest. Looking west from
point just south of Wingate Drive a few hundred feet west of South
Broadway. (Fig. 41)]
