Arches National Park

Arches National Park is a national park that is in Utah's Canyon Country near the town of Moab. It is home to the world's greatest concentration of natural arches, including Delicate Arch, one of the state's most famous icons.

Understand
Arches National Park preserves over 2,000 natural sandstone arches. This area contains the largest concentration of arches found anywhere in the world, including the world-famous Delicate Arch as seen on the Utah state license plate, in addition to a variety of unique geological resources and formations. In some areas, faulting has exposed millions of years of geologic history. The extraordinary features of the park, including balanced rocks, fins and pinnacles, are highlighted by a striking environment of contrasting colors, landforms and textures.

History
Throughout the park, rock layers reveal millions of years of deposition, erosion and other geologic events. These layers continue to shape life in Arches today, as their erosion influences elemental features like soil chemistry and where water flows when it rains. Arches is in a "high desert," with elevations ranging from to  above sea level.

In 1923 Alexander Ringhoffer, a prospector, wrote the Rio Grande Western Railroad in an effort to publicize the area and gain support for creating a national park. Ringhoffer led railroad executives interested in attracting more rail passengers into the formations; they were impressed, and the campaign began. The government sent research teams to investigate and gather evidence. In 1929, President Herbert Hoover signed the legislation creating Arches National Monument, to protect the arches, spires, balanced rocks, and other sandstone formations. In 1971 Congress changed the status of Arches to a National Park, recognizing over 10,000 years of cultural history that flourished in this now famous landscape of sandstone arches and canyons.

Landscape
To many, the most outstanding natural features of Arches are the park's geologic formations. Over 2,000 cataloged arches range in size from a three-foot opening (the minimum considered to be an arch), to Landscape Arch which measures from base to base. Towering spires, fins and balanced rocks complement the arches, creating a remarkable assortment of landforms in a relatively small area.

Two unusual natural features common in Arches intrigue both scientists and visitors: cryptobiotic soil and potholes. Cryptobiotic soil is a living groundcover that forms the foundation of high desert plant life.

Potholes are naturally occurring basins or pools in sandstone that collect rainwater and wind-blown sediment. These potholes harbor organisms that are able to survive long periods of dehydration, and also serve as a breeding ground for many desert amphibians and insects. Both of these communities are very vulnerable to human impacts.

Flora and fauna


The plants and animals in Arches have many adaptations that enable them to survive these conditions. Some species are found only in this area. The diversity of organisms reflects the variety of available habitat, which includes lush riparian areas, ephemeral pools, dry arroyos, mixed grasslands and large expanses of bare rock.

Generally, the trees of Arches grow small and far away from each other. However, mixed stands of Pinyon pine and Utah Juniper, two trees that thrive in dry, rocky environments, can be found throughout the park. In Arches, there is more tree diversity in riparian environments where there is plenty of water. In such locales, trees such as netleaf hackberry, box elder, and Fremont's cottonwood can be found. Nine species of cacti can be found in the park, as well as many types of desert wildflowers and shrubs.

Nearly 50 species of mammals can be found in Arches National Park. Among the more commonly sighted mammals are mule deer, desert bighorn sheep, desert cottontail rabbit, and kangaroo rat. Other large mammals, such as the mountain lion, are present but rarely spotted.

Although Arches National Park is not a birding hot spot, 273 species of birds have been spotted in the park. Species such as Spotted Towhee and Canyon Wren can be found near water in spring and summer. In drier grasslands and pinyon-juniper woodlands of the park, Say's Phoebe, Black-throated Sparrow, Western Meadowlark, Juniper Titmouse, Pinyon and Scrub Jays, and Lucy's and Black-throated Gray Warblers are present. Common Raven will likely be seen by nearly all visitors, and can be spotted throughout the park. Cooper's Hawk and Turkey Vulture are among the birds of prey that glide above Arches' desert landscape.

Arches is home to many reptiles as well. These include 10 species of lizards and 9 types of snakes. Venomous rattlesnakes are present, but are reluctant to attack, so use common sense and caution when observing them.

Climate
Southeast Utah is part of the Colorado Plateau, a "high desert" region that experiences wide temperature fluctuations, sometimes over in a single day. The temperate (and most popular) seasons are spring (April through May) and fall (mid-September through October), when daytime highs average and lows average.

Summer temperatures often exceed, making strenuous exercise difficult. Late summer monsoon season brings violent storm cells which often cause flash floods.

Winters are cold, with highs averaging, and lows averaging. Though large snowfalls are uncommon (except in nearby mountains), even small amounts of snow or ice can make local trails and roads impassable. Winters are also the low season, when the trails are quiet and parking is plentiful.

Local weather conditions and forecasts are available by phone at.

Dust storms can develop in the region, and weather is unpredictable; dust devils are not rare.

By car
The is located 5 miles (8 km) north of Moab along US Highway 191.

By bus
Most visitors see Arches National Park on their own, driving automobiles or riding bikes. However, there are a few privately operated tour companies authorized by the National Park Service to provide visitors with guided trips into the park:



Fees and permits


Entrance fees allow park entrance for seven days. As of 2020 the fees are:
 * $15 per person
 * $25 Motorcycle Fee
 * $30 Private Vehicle Fee
 * $55 Southeast Utah Parks Pass

If the entrance booth is not manned, there is an electronic kiosk to pay the entrance fee and receive a receipt to place on your vehicle's dashboard.

By car
A car is the most common way of exploring the park; most visitors will drive to sites and then take short walks to view the amazing geologic formations of the park. There are several four-wheel drive roads in the park's backcountry that may appeal to those with appropriate vehicles.

By foot
There are numerous trails throughout the park. Hiking at or around sunrise (5-6AM) can provide a less crowded experience and easier parking.

By bike
Although the summer heat can make a bike a masochistic way of viewing the park, in cooler months it can be a popular option. Though there are no bike lanes and traffic can be heavy at times, biking the scenic drive is a great way to see the park. The Salt Valley and Willow Springs roads are less traveled but are more suited to mountain bikes due to washboards, deep sand and other obstacles. Bicycles are only permitted on roads: there is no single track or trail riding in the park. When biking on the main road, please use caution and ride single file on the edge of the lane.

Do


The park is a paradise for photography with reddish brown rocks, distant snow-covered mountains, and fantastic rock formations. As with most places, light can be harsh during the day, so it is best to have the camera ready during the early morning hours and late evening hours. Delicate Arch and the Windows are best photographed at sunset, while the light on Landscape Arch and Double Arch is best near sunrise. Hike to Delicate Arch. The entire arch glows blood red at sunset with the mountains framed within Delicate Arch if you are lucky. The mountains will glow if you wait long enough. In addition, the Windows area is excellent for sunrise photos. Just get to the side where you can see Turret Arch framed by North Window. There is a ledge where you can take your photo although it requires some scrambling over fallen rocks. Those looking for a photograph of Double Arch should be aware that light at sunrise is minimal, although things improve as the sun rises further. Double O Arch is best in the late afternoon if hike through the arch and photograph from the photographers ledge.

The park offers numerous short hiking trails (see above) ranging in difficulty from very easy to moderate. Limited water supplies and a lack of true backcountry trails limit the appeal of backpacking in the park, although backcountry use is allowed. Inquire at the visitor center for details. Rock climbing is not allowed on most features named on USGS maps, but is allowed on other formations.

Wildlife Viewing is also popular. Almost 50 species of mammal are known to live in Arches. Some, like desert cottontails, kangaroo rats and mule deer, are common and may be seen by a majority of visitors. However, many desert animals are inactive during daylight hours or are wary of humans, so sightings can be truly special events. Tracks and scat are the most common signs of an animal's presence. Arches National Park Wildlife has more information on wildlife in the area.

Eat
There is no food available within the park. There is a water fountain at the parking area near the Devil's Garden Trailhead. The nearby town of Moab offers a vast number of restaurants, convenience stores, and grocery stores.

Lodging
There is no lodging within the park, although the nearby town of Moab has an enormous number of hotels to choose from.

Camping
There is only one campground within the park, and reservations are highly recommended. Outside of the park the Bureau of Land Management (BLM) operates several campsites, and there are a number of commercial campgrounds in and around Moab.



Backcountry
Arches is a relatively small park, with very few areas far enough from roads to qualify as backcountry. Outside the developed areas there are no designated trails, campsites, or reliable water sources.

In order to backpack in Arches, you must obtain a backcountry permit at the visitor center. The maximum group size is ten, but smaller groups are strongly recommended to reduce impacts. Permits may not be reserved in advance. Backpackers should know how to navigate with a topographic map, recognize safety hazards and practice low-impact camping specific to the high desert. Primary safety considerations include steep terrain, loose rock, lightning, flash floods, and dehydration.

Pets may not accompany groups in the backcountry.

Stay safe
Stay on the path: Throughout the park and the Southwestern national parks, you will see warnings about cryptobiological soil. Footprints erode the soil and destroy years of growth.

Leave your dog at home: As the climate indicates, there is extreme heat in the summers. Perhaps more importantly, the environment is not supportive of domesticated pets. There are reasons that there are still 1000-year-old corn cobs in archeological sites: items do not deteriorate like they might in your backyard. Cactus and Fido do not make for good bedfellows. Dogs are not allowed on any park trails.

Leave only your footprints, take only photographs: Do not take rocks or any other type of souvenir from the park. Allow your grandchildren's grandchildren to see the park as you see it when you visit it. Throughout the Southwest, you will walk right next to archeological sites. These are rapidly disappearing as people take just one little thing back home.

Summer temperatures can reach or exceed 110°F (43°C), so it is important to carry (and consume) enough liquid to keep you hydrated. One gallon (3.5 L) of water per person per day is recommended. When hiking on open rocky areas, be aware that lightning is a danger during storms. Also, the dry sandstone-dominated terrain is susceptible to flash floods during thunderstorms. The most intense thunderstorms occur from July through September, during monsoon season.

Many of the formations within the park are sandstone and can easily crumble when climbing. Numerous individuals must be rescued each year after they scale a formation and then discover that they cannot easily get back down; know your limitations, and be aware that it is usually easier to climb up a formation than it is to climb back down.
