I’L.VTK VII.— Tho Jurassic Cliffs or White Cliff's, consisting of very massive, cross-hodilcd sandstone. 
This is tho more common aspect of the cliffs in this formation and the view is quite 
typical. Heliotype. (Opposite page 34.) 
-A Midsnmmerday’s Dream on the Coloh. Showing the curious and quaint forms given to 
the remnants of the Jurassic white s.audstone in an advanced stage of denudation. 
Drawn by W. II. Holmes from a photograph. Wood-cut. (Opposite page 36.) 
-Tho Jurassic terrace on the Colob. The subject is of the same general nature as the pre- 
ceding. The curious forms are duo in great part to the cross-bedding of the J urassic 
white sandstone. In the distance are tho summits of the Temples of the Virgen. 
Drawn from a photograph by Thomas Moran. Wood-cut. (Opposite page 38.) 
-The Vermilion Cliffs at Kanab. Illustrating the general character of theTriassic escarp- 
ment east of the Pipe Spring Promontory. The altitude of the cliffs back of the vil- 
lage varies from 1,100 to 1,300 feet. Heliotype. (Opposite page 40.) 
-Land of the Standing Rocks. Showing the characters of the Permian buttes in the heart 
of the Plateau country. The scene here represented is near the junction of the 
Grand and Green Rivers. Drawn from a photograph by W. H. Holmes. Wood-cut. 
(Opposite page 46.) 
-Permian Butte. Hlustrating the character of the upper Permian, with the Shinarump 
conglomerate above. The finely bedded shales are the brilliantly colored beds of 
this form.ation. Drawn by W. H. Holmes. Photo-engraving. (Opposite page 52.) 
-Towers at Short Creek. Showing the buttressed and columnar aspect of the Vermilion 
Cliffs as we approach the Valley of the Virgen from the southeast. These cliffs rise 
about 1,800 feet above the plain. The columnar portion is the great sandstone bed 
of the upper Trias. Drawn by W. H. Holmes. Photo-engraving. (Opposite page 54.) 
-Summit of the Western Temple of the Virgen. Drawn by W. H. Holmes in the style of 
an etching. Wood-cut. (Opposite page 58.) 
-Summit of the Eastern Temple of the Virgen. Drawn by W. H. Holmes. Wood-cut. 
(Opposite page 57.) 
-A pinnacled gable of the Toroweap. Drawn by W. H. Holmes. Wood-cut. (Opposite 
page 84.) 
-The Grand Canon at the foot of Toroweap looking up stream. This view is taken from 
the great esplanade at the brink of the Inner Gorge, The river is about 3,000 feet 
below, and the summit of the wall, of which a fragment is seen in the distant gable, 
is about 1,900 feet above the esplanade. Heliotype. (Opposite page 86.) 
—Dikes in the canon wall. A view from the opposite side of the Inner Gorge. Tho darkly 
shaded portions represent the protruding dikes in the wall. Upon the further brink 
is the remnant of a basaltic cinder cone, now largely undermined and destroyed. To 
the left are sheets of colunmar basalt, and near the left margin the effect of the 
Toroweap fault shearing these beds is shown. Its effect also is shown in the back- 
ground where the horizontal continuity of the strata is broken. Drawn by W. H. 
Holmes. Photo-engr.aving. (Opposite page 92.) 
-Lava falls in the Grand Canon. These occur immediately beneath the scene of the pre- 
ceding illustration. From a X’hotograph. Drawn by Thomas Moran. Wood-cut. 
(Opposite page 98.) 
!. — View of Mount Trumbull from Mount Logan. Mount Trumbull consists of Permian 
strata, heavily capped by basalt of considerable antiquity, probably early Pliocene. 
Upon the right flank of the mountain is a knob, which is a much more recent basaltic 
cinder cone, sending down heavy streams of lava to the plain below. Drawn by W. 
H. Holmes. Wood-cut. (Opposite page 106.) 
-Recent lava flow on the Uiiikaret. This basalt field appears to be extremely recent, and 
the lava looks as fresh as the eruptions which have come firom Vesuvius within the 
last twenty or thirty years. Drawn by W. H. Holmes. Wood-cut. (Opposite page 
112 .) 
. — The Hurricane Fault in the Queantoweap Valley. The fault here has four branches, of 
which three appear in the sketch, and they are very manifest in the topography.
