found in Zion National Park at The Narrows, along Canyonlands National Park's Joint Trail, throughout Capitol Reef National Park, within the San Rafael Swell and the Grand Staircase–Escalante National Monument, especially along the Escalante River drainage including Coyote Gulch. Many more slot canyons are located on public Bureau of Land Management and state-owned lands in southern Utah, in areas surrounding the aforementioned parks and monuments. Buckskin Gulch—one of the longest slot canyons in the world—begins in southern Utah and continues into northern Arizona within the Paria Canyon-Vermilion Cliffs Wilderness. Northern Arizona also has a high concentration of slot canyons including Antelope Canyon and Secret Canyon, which are two of the most famous slot canyons located near Page on land owned by the Navajo Nation. Slot canyons are also located in the valley between U.S. Route 89 and the Vermilion Cliffs in Arizona, and can be seen as one descends into the valley on U.S. 89, but these are on the Navajo reservation and are closed to the public. The Kasha-Katuwe Tent Rocks National Monument's slot canyon trail in New Mexico is unique as it was carved into tuff (volcanic ash). In California, several slot canyons are located within Death Valley National Park. Europe There are a number of slot canyons in Spain, especially in the arid foothills of the Pyrenees, such as on the Balcez river. There is an extensive tourism industry built around canyoning in this region. In Czechia, there is a spectacular slot canyon in the Teplice Mountains called Little Siberia due to the microclimate, which is several degrees colder than the surrounding area. The canyons in Teplice are surrounded by pillar-like rock formations which resemble various animals and were the site where The Chronicles of Narnia were filmed. Drowning danger Local as well as distant storms can cause dangerous flash flooding in slot canyons, and hikers should not enter them if there is any sign of rain in the surrounding area. In many slot canyons, it can be miles before a safe exit or rescue is possible. Australia's Blue Mountains in particular have claimed the lives of several often due to flash flooding. On August 12, 1997, eleven tourists, seven from France, one from the United Kingdom, one from Sweden and two from the United States, were killed in Lower Antelope Canyon by a flash flood.
