History

The park’s history dates back to the mid-1800s when Mormon pioneers first settled in the region. The park’s name, Zion, comes from the Bible and means a place of refuge or sanctuary. The name reflects the park’s importance as a sanctuary for a variety of plant and animal species, including the endangered California condor and the threatened Mexican spotted owl.

Zion National Park was established as a national monument in 1909, and in 1919 it was designated as a national park. Today, the park is managed by the National Park Service and receives over 4 million visitors annually.

Geology

Zion National Park is situated on the Colorado Plateau, which is a large geological province covering parts of Utah, Arizona, New Mexico, and Colorado. The region was once a vast inland sea, and as the sea level rose and fell over millions of years, layers of sediment were deposited on the sea floor. These sediments were eventually uplifted and exposed to the forces of erosion, resulting in the stunning rock formations we see today.

The oldest rocks in Zion National Park are the Navajo Sandstone, which date back to the Jurassic period, approximately 200 million years ago. The Navajo Sandstone is a thick layer of cross-bedded, fine-grained sandstone that forms the towering cliffs that are the most prominent feature of the park. The sandstone was formed from ancient sand dunes that were buried and compressed over millions of years.

Above the Navajo Sandstone is the Kayenta Formation, which is composed of sandstone, shale, and siltstone. The Kayenta Formation is approximately 190 to 170 million years old, dating back to the early Jurassic period. The Kayenta Formation is known for its distinctive iron-rich layers, which give it a reddish-brown color.

The next layer in Zion National Park is the Moenave Formation, which is composed of sandstone, siltstone, and mudstone. The Moenave Formation is approximately 170 to 145 million years old, dating back to the middle to late Jurassic period. The Moenave Formation is known for its thin, white sandstone layers, which are often interbedded with red sandstone layers.

Above the Moenave Formation is the Temple Cap Formation, which is composed of sandstone and conglomerate. The Temple Cap Formation is approximately 145 to 135 million years old, dating back to the late Jurassic period. The Temple Cap Formation is known for its distinctive cross-bedded sandstone layers, which are often capped with a layer of dark volcanic rock.

The youngest rocks in Zion National Park are the Carmel Formation, which is composed of limestone, sandstone, and shale, and the Entrada Sandstone, which is composed of cross-bedded sandstone. The Carmel Formation is approximately 135 to 155 million years old, dating back to the late Jurassic period, while the Entrada Sandstone is approximately 135 to 160 million years old, dating back to the late Jurassic to early Cretaceous period.

The geology of the park is characterized by a series of steep-walled canyons and narrow gorges, which have been carved out by the erosive forces of water and wind. One of the most famous of these canyons is the Zion Canyon, which is approximately 15 miles long and up to half a mile deep. The canyon was formed by the Virgin River, which has been eroding the Navajo Sandstone for millions of years.

Another unique feature of the geology of Zion National Park is the presence of rock arches. These natural arches are formed when water and wind erode the rock layers, leaving behind a thin, flat layer of rock that is suspended between two larger rock formations. The most famous of these arches is the Kolob Arch, which has a span of approximately 287 feet and is one of the largest natural rock arches in the world

Features & Activities

One of the park’s most iconic features is the Zion Canyon, which is a 15-mile-long gorge cut by the Virgin River. The canyon is home to some of the park’s most popular hiking trails, including the famous Narrows hike, which takes hikers through the river and narrow slot canyons.

The park’s sandstone cliffs are also a popular attraction, with the most famous being the 2,200-foot-high Zion Canyon Narrows. The park’s cliffs are home to a variety of unique plant and animal species, such as the desert bighorn sheep and the Zion snail, which is only found in the park.

The park offers a wide variety of outdoor activities, including hiking, camping, rock climbing, canyoneering, and horseback riding. The park has over 90 miles of hiking trails, ranging from easy walks to challenging hikes for experienced hikers. The park also offers guided tours and ranger-led programs, allowing visitors to learn more about the park’s history, geology, and wildlife.

One of the most popular hiking trails in the park is the Angels Landing trail. This trail is a 5.4-mile round trip that takes hikers up to the top of a towering sandstone peak. The hike is strenuous and requires hikers to climb up a narrow spine with steep drop-offs on both sides. However, the views from the top are breathtaking and make the hike well worth the effort.

Another popular hike is the Zion Narrows hike, which takes hikers through the Virgin River and narrow slot canyons. This hike is unique and challenging, as hikers must wade through the river and navigate through narrow canyons with high walls. The hike is only possible during the warmer months when the water levels are low.

For those interested in rock climbing, Zion National Park offers some of the most challenging and rewarding climbs in the world. The park’s sandstone cliffs provide a variety of climbing routes, from easy boulder problems to multi-pitch climbs for experienced climbers. Climbing is allowed in the park with a permit, and the park has several guide services that offer guided climbing tours.

Camping is also a popular activity in Zion National Park, with three campgrounds within the park. The campgrounds offer a range of amenities, including restrooms, showers, and picnic areas. The park also offers backcountry camping permits for those interested in exploring the park’s wilderness areas.

Despite its popularity, Zion National Park faces several challenges, including overcrowding and environmental impacts. The park has implemented a number of measures to address these issues, including a shuttle system that reduces traffic congestion and limits the number of visitors in certain areas. The park also has a number of initiatives to reduce waste and protect the park’s natural resources.
