| FORMATION | PRESENT DEPTH (Feet) | GEOLOGICAL AGE | DESCRIPTION | |
|---|---|---|---|---|
| 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 Cretaceous | Gray to buff sandstone and drab shales, alternating with occasional coal beds. | |
| McElmo Formation | 800 | Lower Cretaceous | Shales and sandstones of many 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 Conglomerate | 100 | Late Triassic | Brown, yellow and gray conglomerate and sandstone, celebrated for its petrified trees. | |
| Moenkopi Formation | 1600 | Early Triassic | Purple, yellowish-gray, dull 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 Carboniferous | The same gray, massive limestone seen on the Rim of the Grand Canyon. The road from Cedar City to Zion Canyon runs over it for several miles. |
II.—FROM THE GRAND CANYON RIM TO THE GRANITE GORGE
| Kaibab Limestone | 800 | Late Carboniferous | Grand Canyon | Gray limestone formed in the sea, as indicated by many Carboniferous fossil shells. At the Grand Canyon it is the surface rock. In the Plateau Country to the north, it lies at the bottom of the series. |
| Coconino | 300 | Carboniferous | Very massive, cross-bedded yellow sandstone. | |
| Supai Formation | 1100 | Carboniferous | Alternating red shale and red and brown sandstone, the latter forming low cliffs. This constitutes the greatest red body of the Canyon wall. | |
| Redwall Limestone | 600 | Carboniferous | Extremely hard blue or gray limestone, forming the greatest cliff of the Grand Canyon. It is stained a vivid red by the wash of the red Supai shales above. The cliff is a conspicuous feature of the Canyon everywhere. | |
| Missing Strata | Devonian Silurian Ordovician | During Devonian, Silurian and Ordovician times, extensive strata were deposited upon the Cambrian rocks below, but were wholly eroded away during a long uplift period and the limestone known as the Red Wall was deposited on the Tonto during a succeeding period. | ||
| Tonto Group | 950 | Cambrian | Olive green shale and limestone, forming the broad green floor of the Grand Canyon, through which winds the Granite Gorge. | |
| Unkar and Chuar Groups known as the Grand Canyon Series | Algonkian | Greenish sandstones, fine quartzites and vividly red shales, once 13,000 feet thick, but here eroded away till they appear only in places. | ||
| Granite Gorge | 1200 | Archean | Schists metamorphosed from sedentary rocks, and intruded igneous rocks. |
