12 Fun Facts About Arches National Park
1. Arches National Park has the largest concentration of natural arches in the world!
How many arches are in Arches National Park?
There are over 2,000 arches at Arches National Park. The exact number of arches is changing all the time as new ones form and old ones collapse.
Did you know there are four types of natural arches in the park?
- Cliff Wall Arches appear on the side of or adjacent to rock walls or cliffs.
- Free-Standing Arches are the most obvious kind of arch: they stand alone, independent of other rock walls or fins. A few arches of this type have been called “windows” for the scenic views they frame.
- Pothole Arches form when a pothole on top of a rock mass merges with an alcove on a rock face.
- Natural Bridges sit astride a stream or stream channel.
2. The most famous arch in Arches National Park is featured on Utah’s license plate
The most famous arch in the national park (the world?) is Delicate Arch. It is a rare completely free-standing arch with a dramatic location. It’s the largest free-standing arch in the park, with an opening 346 feet high and 32 feet wide.
Delicate Arch is reached at the end of a 3-mile hike that goes along a narrow ledge near the end, the arch sits atop the rim of a sandstone bowl near the edge of a cliff. It will collapse one day, btu for now,
3. There have only been a few deaths at Arches National Park
It is possible to slip and fall to your death in Arches national park. However, there have only been 6 deaths in total. 2 falls, one environmental, 2 natural deaths and one undetermined. That may seem a lot, but compared with the 900 people who have died in Grand Canyon National Park, that’s not many at all!
If this kind of thing is of interest, there’s a fun book Over the Edge: Death in Grand Canyon – get it here.
4. The Balanced Rock is the Size of Three School Buses
Balanced Rock is not an arch, but is nonetheless one of the most iconic features in Arches National Park. It looks like a large rock pillar with another rock balanced on top of it. The total height is 128 feet tall – and the rock ‘balanced’ on top is as big as three school buses!
The name is a misnomer, however. Although it looks – from some angles – as if the large rock is balanced on top f the pedestal, they are actually joined together. They are two different types of rocks – the top rock is Entrada Sandstone and the pedestal is Dewey Bridge mudstone.
One day is will erode so much that it will fall down. In fact, it used to have a smaller sibling “Chipo-Off-The-Old-Block”, which collapsed in 1975-76.
5. The 4th longest natural span in the world is in Arches National Park
Landscape Arch has a span of 306 feet, making it the longest natural arch in North America. Its length is surpassed only by three natural arches in China.
To get to the arch, take the easy 1.8-mile round trip trail that starts the Devil’s Garden Trail. You can continue on to Double O Arch or turn around. Read my full Devil’s Garden Trail Guide.
6. The arch with the tallest opening is Double Arch
The southern span of Double Arch is an incredible 112 feet tall. It’s also the third-widest arch in the park, at 144 feet across.
The arch is reached along a short trail in the Windows Section.

7. Temperatures can vary by over 40 degrees in one day
Arches National Park is in the middle of the desert – but also at a high altitude. Day time temperatures in summer can soar well over 100°F and it can snow in winter. In one day, day and night time temperatures can vary dramatically. Weather can also change rapidly, so it’s important to always wear layers.
These extremes in temperatures help form the natural arches. Water seeps into cracks in the rocks in the day, then freezes at night, expanding the cracks and helping weather the rocks.
8. Arches National Park is officially an International Dark Sky Park
Arches National Park was designated an official International Dark Sky Park in 2019. This means that area is free of light pollution and is one of the best places in the United States for star gazing and to see the Milky Way.
When getting to your photography spot, be sure to wear a headlamp with a red light. The red light is less harsh than white light, so improves your night visions. You can get one here if you need one.
9. Arches National Park has featured in many iconic movies
Do you remember the opening scene of Indiana Jones & The Last Crusade? The boy scouts (including a young Indiana Jones) ride horses through the Double Arch section of Arches National Park.
How about the scene in Thelma and Louise where they take the trooper’s gun and leave him locked up in the trunk of his car? That was filmed at the Courthouse Towers section of Arches National Park.
10. Arches National Park Has paintings that are 4,000 years old
The Courthouse Wash panel at Arches National Park feature pictographs that are between 1,400 and 4,000 years old. These incredible hand paintings reveal even more detail when photographed with infrared light. The pictographs lie just outside the park entrance and there is a small parking area and a short walk to get to get to them.
11. The entire park used to be under water
In between the sections of the national park that have arches is a giant salt valley. This whole area dry seabed used to be an inland sea. The sand formed dunes that petrified and turned into the rock that then eroded to form the natural arches in the park.
12. The soil in Arches National Park is alive
What looks like dark soil on the ground is biological soil – or cryptobiotic crust. It’s made up of cyanobacteria, fungi, lichen, algae, and mosses. The biological crust lies dormant when it’s dry and grows when it gets wet. It helps prevent soil erosion and is an essential part of the local ecosystem. It moves around when wet and plays an essential role in protecting the land from erosion.
You can tell it by its darker color and sponge-like appearance. It can take decades to grow and can be killed in an instant if you walk on it, so it is super important to stay on trails and avoid walking on the living soil.
