Slot canyon facts for kids
A slot canyon is a very special type of narrow channel or pathway carved into rock. Imagine a long, deep crack in the earth with tall, smooth rock walls! These canyons are usually found in sandstone or other sedimentary rock. They are much deeper than they are wide, often 10 times deeper than their width, and sometimes even 100 times! You can find many of these amazing places in the dry areas of the southwestern United States, especially in a region called the Colorado Plateau. Slot canyons are beautiful but can be dangerous because of sudden floods. They also have unique plants and animals that are different from the drier areas around them. Some slot canyons can be less than 1 metre (3 ft) wide at the top but drop more than 30 metres (100 ft) to the bottom!
Most slot canyons form in sandstone and limestone rock. However, they can also be found in other rock types like granite and basalt. Only a few streams create slot canyons. This happens because of a special mix of rock types and how much rain an area gets.

Exploring Slot Canyons
What Are Slot Canyons?
Slot canyons are natural wonders formed over thousands of years by flowing water. Even a small amount of water, carrying sand and pebbles, can slowly carve through solid rock, creating these incredible, winding passages. The walls are often smooth and colorful, showing layers of rock that tell a story of Earth's past. Exploring them feels like stepping into another world!
Where Can You Find Them?
Slot canyons exist in many parts of the world, especially in places that don't get a lot of rain. These dry conditions help preserve their unique shapes.
Slot Canyons in Australia
Australia has a huge number of slot canyons, with over 900 found in the Blue Mountains, west of Sydney. These canyons are mostly in a long strip of sandstone. Many are in the Wollemi Wilderness and are quite hard to reach. Some parts of these canyons have never even been explored by people! A few are popular for "canyoners" (people who explore canyons) during the summer. For example, the Grand Canyon near Blackheath has a path along its edge, but to see it all, you might need to use ropes to go down (called abseiling or rappelling) or swim through water.
Other slot canyons in Australia can be found in remote areas like Karijini National Park and the Bungle Bungles in Purnululu National Park, both in Western Australia. You can also find them in Carnarvon Gorge in Queensland.
Slot Canyons in the United States
The southern part of Utah is home to more slot canyons than almost anywhere else in the world—over a thousand! You can find them in famous places like Zion National Park (especially a part called The Narrows), Canyonlands National Park, Capitol Reef National Park, and the Grand Staircase–Escalante National Monument. One of the longest slot canyons in the world, Buckskin Gulch, starts in southern Utah and goes into northern Arizona.
Northern Arizona also has many slot canyons, including the very famous Antelope Canyon and Secret Canyon. These are near Page on land owned by the Navajo Nation. It's important to remember that these lands are sacred and require special permission to visit.
In New Mexico, the Slot Canyon Trail at Kasha-Katuwe Tent Rocks National Monument is special because it was carved into tuff (rock made from volcanic ash). More can be found in the basalt mesas around Mt. Taylor. The Plaza Blanca Slot Canyon, with its white cliffs, even inspired some paintings by the artist Georgia O'Keeffe.
In California, you can explore several slot canyons within Death Valley National Park.
Slot Canyons in Europe
Europe also has its share of slot canyons. In Spain, especially in the dry foothills of the Pyrenees mountains, you can find many. This region is popular for "canyoning" tourism, where people explore these natural waterways.
In Czechia, there's a spectacular slot canyon in the Teplice Mountains called Little Siberia. It's known for its cooler temperatures and pillar-like rock formations that look like animals. This area was even used as a filming location for The Chronicles of Narnia movies!
Staying Safe in Slot Canyons
Exploring slot canyons can be an amazing adventure, but it's very important to be aware of the dangers. These canyons can have falling rocks, slippery surfaces, very narrow passages, deep pools of cold water, and places where you have to swim or climb. Sometimes, getting help from rescue teams can be difficult because of how remote and enclosed these places are.
Understanding Flash Floods
The biggest danger in slot canyons is flash floods. A flash flood is a sudden, powerful rush of water that can fill a canyon in minutes. These floods can be caused by storms happening miles away, even if it's sunny where you are! The water collects and rushes down the narrow canyon, becoming incredibly strong and dangerous.
It is extremely important that hikers never enter a slot canyon if there is any chance of rain in the surrounding area. Once you are inside, it can be many miles before you find a safe exit or a place where rescuers can reach you.
Important Safety Lessons
Sadly, there have been incidents where people have lost their lives due in slot canyons to flash floods or dangerous water conditions. On January 31, 1982, three people died in Claustral Canyon because of a flash flood.
A well-known incident happened on August 12, 1997, in Lower Antelope Canyon. Eleven tourists were killed by a flash flood. Very little rain fell at the canyon that day, but a big thunderstorm seven miles upstream sent a huge amount of water rushing through. The only survivor was the tour guide, who had special training for fast-moving water. After this tragedy, many safety improvements were made. Today, strong ladder systems are bolted into the rock, and special nets can be deployed at the top of the canyon. There's also a weather radio from the National Weather Service and an alarm horn to warn visitors of danger.
