Cedar Breaks, some 2,000 feet higher than Bryce Canyon, is eroded from
similar formation to that at Bryce Canyon.
FORMATION PRESENT GEOLOGICAL DESCRIPTION
DEPTH AGE
(_Feet_)
Basalt Bryce Sheets of very dark lava,
resting unconformably upon
the Pink Cliff below.
Pink Cliff 500 Eocene ″ Richly colored shales,
limestones and conglomerates,
most of them red, and
containing fossils.
Cretaceous Rocks 3000 Upper Gray to buff sandstone and
Cretaceous drab shales, alternating with
occasional coal beds.
McElmo Formation 800 Lower Shales and sandstones of many
Cretaceous colors.
Jurassic Rocks 600 Jurassic Drab shale, chocolate colored
limestone and occasional gray
gypsum beds.
White Cliff 1000 Jurassic Zion White, cross-bedded
sandstone. Modern geology
considers the White and
Vermilion Cliffs part of the
same formation, but
scenically they will always
be distinguished.
Vermilion Cliff 2000 Jurassic ″ Brilliant red, variegated,
massive sandstone.
Chinle Formation 350 Late Triassic ″ Mauve sandstone above, purple
and red shale below.
Shinarump 100 Late Triassic Brown, yellow and gray
Conglomerate conglomerate and sandstone,
celebrated for its petrified
trees.
Moenkopi 1600 Early Purple, yellowish-gray, dull
Formation Triassic red and coffee-brown
sandstones, in a great body
of rich red shale. Contains a
few layers of hard red, brown
and gray limestone and some
light-colored gypsum beds.
Known also as the Belted
Shales.
Kaibab Limestone 1800 Late The same gray, massive
Carboniferous limestone seen on the Rim of
the Grand Canyon. The road
from Cedar City to Zion
Canyon runs over it for
several miles.
