Entering Zion Park from the East side, one of the first sites to catch the eye is the Checkerboard Mesa, the most famous landmark in Zion National Park. It’s geology is unique due to the cross-bedding. It showcases the rock formation that has eroded over millions of years in rare sections of Navajo Sandstone.
The horizontal furrows were cut during the Jurassic period by blown sands of the huge ancient sand dunes that once stood in place of the Monoliths you see today. The vertical slits were formed much later after brittle rock had formed.The formations of Zion are still changing today, slowly over time the great monoliths you see will return to the Great Sand Dunes from where they were born in ancient days. The forces of Nature will force their way through layers of sedimentary rock every day of our future, just as they have in our past. The largest monolith in the world, the great white throne will be reduced to layers of sand.

The East section of Zion Park is known as "slick rock country.” Here the rocks are a mixture of white and varied tints of brown or orange, due to the minimal presence of iron-oxide that the other layers of sandstone posses in greater amounts.
The slickrock section of Zion showcases the powerful effects of erosion over a great period of time. The geology of Zion transforms dramatically as one travels from the east section of the park through Zion's long tunnel.

The 1.1 mile long Tunnel was blasted and cut in the thick Navajo sandstone during early 1900. Imagine cutting through 2,000 foot thick sandstone with the machinery available in the early 1900’s. In those days the whole process was considered a technological wonder.
My Grandmother lived here during the time the tunnel was cut and tells vivid stories of the process. Zion National Park was the first area to be named a National Park in Utah and as such is the oldest of the Parks. The scenic drive through the tunnel to the east section of the park is often said to be the most magnificent.
1.1 mile long Zion tunnel
The Canyon Overlook Trail offers an incredible view of the lower Zion Canyon. The trail climbs above the1.1 mile long Zion-Mt.Carmel tunnel, one of two tunnels in Zion Park. This trail is an easy 1 mile hike that leads the hiker through hoodoos and a cool, wet rock alcove with hanging gardens. The trail ends in a nest of Hoodoos high above the canyon floor. Looking down over the fenced edge you see the stunning view of the Canyon floor from high above with sandstone cliffs rising in every direction. Directly below is Pine Creek, following the creek up stream from this point there are deep swimming holes surronded by giant boulders. If you are driving through the park, think about taking the time to hike this short trail. The view from the point is the most incredible in Zion Park. After leaving the tunnel there is a rapid drop to the bottom of the canyon floor as you enter the area of the Kayenta Formations and the towering Navajo.

Note the massive Beehives in the photo to the left, exhibiting a show of turrets carved into the very top of the Navajo sandstone. As you travel down the six switchbacks, look for the Great Arch (photo below) carved into the mountain side by the storms of nature and time. The unique geology of this arched structure was caused from jointing. Zion Park is a small park, measuring only 147,000 acres, but the diversity of plants, animals, rock formations is amazing. |

Like Zion’s other features, the park hosts a wide variety of hikes, from a short jaunt to difficult over night backpacking Park at the junction of Scenic Byway 9 and the turn off to Zion Canyon. A short shuttle ride will take you to the end of the Canyon. Zion Canyon was carved over time by the steady flow of water from the Virgin River, a process that continues even today. The river seems mild, but it is still capable of transporting tons of debris down its stream. |
An isolated Hoodoo in Bryce Canyon located along the Mosey Cave trail
The Geology in Bryce Canyon National Park - The hoodoos in Bryce literally crowd together to form the magnificent views. The hoodoo formations are crowded next to each other making up the twenty mile long series of amphitheaters of Bryce Canyon. The hoodoos of Bryce are sculpted Claron rock formations. Claron is a colorful combination of pinks and oranges caused by trace amounts of iron oxide, the white formations you see in the park are lacking the iron oxide. The patterns of Bryce’s rock formations show off their unique crisscross design formed though a long process of freezing and thawing.

The process still continues today, as the rock formations continue to be designed by nature. Water weeps into fractures at the rocks surface turning to ice as temperatures drop, then the ice expands pushing the fractures open. The overnight freezing and daytime thaw are abundant, occurring 2-3 hundred times a year.
Comparing the Claron of Cedar Breaks and Bryce Canyon shows that that of Cedar Breaks is thicker and more colorful. This is a smaller amphitheater, but certainly worth the visit. Cedar Breaks is located off Hwy 14.
Turning off ten miles past Mt. Carmel Jct. takes you to one of the few entrances of the Grand Staircase National Monument. Follow the Bench road located in the tiny town of Glendale into the Monument. Stay on this graded dirt road for fifteen miles and you come to a turnoff that leads to the Lick Wash trail. This is a wonderful and secluded slot canyon. Return to Mt. Carmel Jct. and head towards Kanab to reach the North Rim of the Grand Canyon. The Slot Canyon hikes in the Grand Monument are Incredible!
The drive from Mt.Carmel Jct. to the North Rim of the Grand Canyon is beautiful. From Mt. Carmel Junction (the Jct. to Zion, Bryce and Grand Canyon) to Kanab the light and dark stained Vermillion Cliffs are eye catching with a beauty of their own much different of that from any of the parks in Southern Utah. Traveling down Scenic Byway 89A on the way to the Grand Canyon leads you through the Kaibab Forest. Here from a distance the five stairsteps of the Grand Staircase National Monument are evident, no wonder the name Grand Staircase.
The Monument is huge, consisting of two-million acres of plateaus, mesas, buttes, slot canyons all in a primative setting. This staircase extends 150 miles from bottom to top and rises 3500 feet in elevation. The old bottom step is seen in the photo above, it is the North Rim of the Grand Canyon and stretching past all other steps to the young section of Bryce Canyon. Each of the main risers in the staircase are named for their colors: Pink, White, Grey, Vermillion and Chocolate.The Monument is huge, consisting of two-million acres of plateaus, mesas, buttes, slot canyons all in a primative setting.

The Canyon is two billion years in the making, over a mile deep and almost three-hundred miles long, the Grand Canyon is a geologic wonder. Over vast amounts of time mountains were built, eroded away and sediment set down in unparalleled configurations and forms, shifting, uplifting - forming the Grand Canyon. Millions of years ago water flowed through the mountains, starting as just a stream, the Colorado River carved its way through the many layers of soft rock. The erosion continued until the stream of water became the Colorado River
Grand Canyon North Rim
The Geology of the Grand Canyon - Located near Zion National Park (less than 2 hour drive from Zion) is the North Rim of the Grand Canyon. This section of the Canyon is said to be more spectacular than the crowded south side. The view of the North Rim, is exilerating. The North Rim is 1,000 feet higher (9,000 feet) than the south, leading to cooler temperatures and a different environment.
The force of the water drilled through the Kaibab Limestone to the Coconio Sandstone and Hermit Shale, and on through the other layers until, finally – the oldest rocks existing were uncovered. This wonder located in Arizona is a must to see. Mt. Carmel Jct., the junction to Zion National Park, Bryce Canyon, Cedar Breaks, Grand Staircase Monument and the Grand Canyon offers you a location from which you can visit all the wonders of Color Country.
