Sep 05, 2013 Canyoneering in Zion National Park turns deadly when four canyoneers are caught in a massive flash flood, pinning them under a 300 foot waterfall. Behunin Canyon, Utah. See more at ericrhanson.com. Slot canyons are particularly dangerous due to the risk of flash floods. Storms more than 50 miles (80 km) away can send 100-foot-high (30 m) walls of water down the narrow canyons, and hikers have been killed in such events. Hikers should check conditions carefully and not rely on. I filmed a flash flood in Buckskin Wash / Gulch on 7/29/17. Earlier that day a group of 7 hikers had been dropped off at the Wire Pass trail head to hike Buckskin Gulch. They were later hit.
A slot canyon is a long, narrow, deep and tortuous channel or drainageway with sheer rock walls that are typically eroded into either sandstone or other sedimentary rock. A slot canyon has depth-to-width ratios that typically exceed 10:1 over most of its length and can approach 100:1. The term is especially used in the semiarid western United States, including the Colorado Plateau region. Slot canyons are subject to flash flooding and commonly contain unique ecological communities that are distinct from the adjacent, drier uplands.[1] Some slot canyons can measure less than 1 metre (3 ft) across at the top but drop more than 30 metres (100 ft) to the floor of the canyon.
Many slot canyons are formed in sandstone and limestone rock, although slot canyons in other rock types such as granite and basalt are possible. Even in sandstone and limestone, only a very small number of streams will form slot canyons due to a combination of the particular characteristics of the rock and regional rainfall.

Slot canyons around the world[edit]
Slot canyons are found in many parts of the world, predominantly in areas with low rainfall. Some of the best-known slot canyons are to be found in the Southwestern United States. Other significant areas include the Sierra de Guara in northern Spain, the Pyrenees on the border of France and Spain, and the Blue Mountains in New South Wales, Australia.
Australia[edit]
The largest known area of slot canyons in Australia is in the Blue Mountains, west of Sydney. They occur in a narrow band of sandstone that runs roughly 30 kilometres (19 mi) from east to west, and about 100 kilometres (62 mi) from south to north. The majority of these canyons are in the Wollemi Wilderness, and are difficult to access. A small number are regularly visited by canyoners on weekends in summer. The Grand Canyon, near Blackheath, has a tourist track along its rim, but requires abseiling (rappelling) or swimming to visit fully.
Sandstone slot canyons can also be found in a few more remote parts of Australia, including Karijini National Park and the Bungle Bungles in Purnululu National Park, both in Western Australia, and Carnarvon Gorge in Queensland.
United States[edit]
Southern Utah has the densest population of slot canyons in the world with over one thousand slot canyons in the desert lands south of Interstate 70.[2] Utah's slot canyons are 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.
Drowning danger[edit]
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.[3] In many slot canyons, it can be miles before a safe exit or rescue is possible.
On August 12, 1997, eleven tourists, including 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.[4][5] Very little rain fell at the site that day, but an earlier thunderstorm had dumped a large amount of water into the canyon basin, seven miles upstream. The lone survivor of the flood was tour guide Francisco 'Poncho' Quintana, who had prior swift-water training. At the time, the ladder system consisted of amateur-built wood ladders that were swept away by the flash flood. Today, ladder systems have been bolted in place, and deployable cargo nets are installed at the top of the canyon. A NOAA Weather Radio from the National Weather Service and an alarm horn are stationed at the fee booth.[6]

Slot Canyons Utah
The Buckskin Gulch, a canyon in southern Utah, is one of the main tributaries of the Paria River, which is itself a minor tributary of the Colorado River. It is the longest and deepest slot canyon in the southwest United States and may be the longest in the world.[citation needed] As such it is one of the premier destinations for slot canyon hikers, and receives a high amount of foot traffic.
At over 13 miles (21 km) in length it is often visited in conjunction with the longer Paria Canyon, although some prefer to make a long day trip out of the hike. With a distance of 20 miles (32 km), hiking this canyon in one day is possible. Wire Pass, a short tributary to the Buckskin, is an ideal alternative for a short day hike that still takes hikers through the narrow, curving features that are the hallmark of slot canyons.[1]
Access[edit]
Buckskin Gulch is reached via US Highway 89 or U.S. Highway 89A, and is approximately halfway between the towns of Kanab, Utah and Page, Arizona. There is a ranger station right near the bridge over the intermittently flowing Paria River, and the dirt road to the Gulch is approximately 2 miles (3.2 km) west of the station. You then go 8.4 miles (13.5 km) down the dirt road to the jump-off point. The Wire Pass entrance shares the same trailhead, Wire Pass Trailhead, with the equally spectacular Coyote Buttes, home to The Wave, a famous sandstone rock formation.
Regulations[edit]
Permits are required by law for both day hiking and overnight backpacking in the Buckskin Gulch-Paria Canyon-Vermilion Cliffs Wilderness Area. Permits can be obtained from the Bureau of Land Management office online. Only twenty overnight permits per day are allowed and group sizes are limited to ten persons. The overnight fee is $5.00 per person per day while day use permits are $6.00 per person per day. There is also a $6 fee per dog, per day. Due to the popularity of the canyon, permits typically sell out several months in advance. Campfires are prohibited and human waste cannot be buried and must be packed out in order to preserve the pristine condition of the area.[2][3] Buckskin Gulch lies within the Grand Staircase-Escalante National Monument and Paria Canyon-Vermilion Cliffs Wilderness Area of the Bureau of Land Management.
Hazards[edit]
Wire Pass and Buckskin Gulch generally do not require rappelling equipment, but there may be a few pour-offs or the necessity to wade in ankle- to chest-high water and/or mud. Hiking Buckskin Gulch is extremely challenging. Be prepared with extra clothes to wear for warmth after wading through cold, stagnant pools of water, rather than depending on campfires, which are prohibited in this confined environment. Additionally, the lack of sunlight in the canyon can make it much colder than the surrounding exposed desert. At one point along the route, there is a 15-foot (4.6 m) drop-off that usually has rope, but it is a good idea to bring at least 30 feet (9.1 m) of rope to navigate some of the pour-offs. Small areas of quicksand can also be found along the route.
Slot canyons are particularly dangerous due to the risk of flash floods. Storms more than 50 miles (80 km) away can send 100-foot-high (30 m) walls of water down the narrow canyons, and hikers have been killed in such events. Hikers should check conditions carefully and not rely on seeing the sky to judge the weather. If there is even a slight chance of rain, do not enter slot canyons.
