Period: 300 BCE to 250 BCE
Permian Period
300 - 250 million years ago -
275 BCE
Sedimentation
275 million years ago
During this time, the land that would become Zion was covered by a shallow sea. As sand, gravel and mud eroded from the surrounding mountains, the materials were deposited in layers. As they accumulated, the basin started to sink but the top layer remained near sea level. This process continued over 10,000 feet -
Period: 252 BCE to 201 BCE
Triassic Period
252 - 201 million years ago -
240 BCE
Moenkopi
240 million years ago
This layer of Zion was deposited with shallow seas. There are deposits of sandstone, mudstone and limestone. They contain ripple marks which proves this desert climate was around the sea. There are also footprints of reptiles and amphibians that have been preserved in the mudstone. -
215 BCE
Chinle
215 million years ago
This layer is the Petrified Forest member, and the deposits found here were from low energy rivers. The layers are bright and colorful mudstone, clay and weathering ash. -
Period: 210 BCE to 190 BCE
Late Triassic/Early Jurassic
210 - 190 million years ago -
200 BCE
Moenave
200 million years ago
This formation is thin layers of red/brown sandstone, siltstone that was deposited in streams floodplains and lakes. This material erodes easily which makes it highly visible. This formation is also where you can find footprints left behind by Dinosaurs walking in the muddy sediments. -
Period: 195 BCE to 165
Jurassic
195-165 million years ago -
190 BCE
Kayenta
190 million years ago
The Kayenta Formation is red/brown and pink sandstone, mudstone and siltstone deposited in an environment similar to Moenave. The layers of sandstone represent actual stream channels -
180 BCE
Navajo Sandstone
180 million years ago
The Navajo Sandstone is thick layers of cross-bedded sandstone formed by windblown sand dunes in a desert. This area had significantly dried out creating the largest known sand desert in history. Cross-beds are diagonal patterns found in rocks. It shows the direction of the wind. In the photo above they dip downwards showing the wind went left to right -
170 BCE
Temple Cap
170 million years ago
The Temple Cap is Sandstone and mudstone formed by costal sand dunes. The environment Zion was born in was complicated and the Temple Cap preserves the history of it. There was a shallow sea that came into the area, and it deposited many different types of rocks. The Temple Cap is very easy to see but hard to get to -
160 BCE
Carmel
160 million years ago
Only a portion of the Carmel layer remains in Zion, the rest has eroded away. It is not visible from the canyon but can be seen near Zion's east entrance on top the Temple Cap.
The Carmel Formation has lots of marine fossils, similar to those of today. They were left behind and deposited when the Sundance Sea had returned inland. -
Period: 145 BCE to 66 BCE
Cretaceous
145-66 million years ago -
120 BCE
Cedar Mountain Formation
The Cedar Mountain Formation is the highest point in Zion National Park. These sediments were deposited by rivers flowing in the mountains. All sedimentary layers younger than Cedar Mountain have eroded away but could be found where erosion has not cut so deep yet. -
13 BCE
Elevation 10,000 ft
13,000,000 years ago, Zion first elevated to 10,000ft in elevation. -

The People History Starts
-
First European Exploration
Silvestre Velez de Escalante and Dominguez Escalante explored the Kolob Canyons -
Mormon Settlers
Zion's first settler, Isaac Behunin lived in a log cabin near where Zion Lodge is today. Mormon settlers left their mark, giving Zion the name that would eventually stick. Mormons awed by the immense beauty of the canyon, referred to it as, "Zion" since its magnificence reminded them of a heavenly city described in the Little Zion - Old Testament. -
Zion becomes Famous

Zion Canyon Survey
Federal Land Survey of Zion Canyon -
Declared a National Monment
The canyon was declared a National Monument by President Taft after receiving the survey results. The Paiute name Mukuntuweap (sacred cliffs or straight canyon) that Powell used during his exploration was chosen and farming of the canyon by Mormon settlers came to an end. -
Zion becomes "Zion National Park"
Congress declares the Monument to be Zion National Park, becoming Utah's oldest National Park. -
Zion gets bigger
President Obama signs the Omnibus Public Land Management Act of 2009, adding 124,406 acres of park land as Zion Wilderness.
