Visitor Guide National Park Service U.S. Department of the Interior Arches We Need Your Help The La Sal Mountains with the Windows Section in the foreground NPS / PAUL STOLEN BY RACHEL JOHA Arches National Park is a destination for over 1.5 million people a year. Numbers like that can have a huge impact on the landscape. No matter your experience in the outdoors, we all play a role in protecting and preserving our public lands. The Seven Principles of Leave No Trace are helpful guidelines to minimize your impact here at Arches or anywhere you visit. Plan Ahead and Prepare Plan your trip activities to match your goals, skills, and abilities. Research the park and current conditions ahead of time. Bring enough water, a map, food, and appropriate gear so you don’t need rescuing. Dozens of hikers at Delicate Arch and Devils Garden get in trouble every year from lack of preparation. Dispose of Waste Properly “Pack it in, pack it out.” Don’t leave behind any trash or food scraps. In arid climates like ours, organic litter like orange peels or nut shells does not decompose quickly. “Go before you go.” Before starting a hike, use the bathroom and carry a human waste disposal bag for emergencies. Travel and Camp on Durable Surfaces Concentrating your activity on nonvegetated durable surfaces (e.g. a trail, rock, a drainage path, or pavement) spares vegetation, sand dunes, and soil crust from damage. Don’t walk through desert puddles, whether they are wet or dry. They contain living organisms. Leave What You Find Chalking, carving, scratching, or painting on the rocks is considered graffiti and is illegal. Cairns (stacks of rocks) mark routes in the park. Don’t change existing ones or build your own, which can mislead other hikers. Welcome to Arches Drink water. It is easy to become dehydrated here, even in cold temperatures. Plan on drinking at least 1 gallon (4 L) of water per day. You can get water at Arches Visitor Center and Devils Garden. Minimize Campfire Impacts Never leave a fire unattended, and thoroughly extinguish all fires. Fires are only allowed in designated pits at Devils Garden Campground and in picnic areas. Collecting firewood or kindling is not allowed in the park. Respect Wildlife Do not feed wild animals. Secure your food and trash so clever ravens can’t get into it. Keep pets under control and on a leash so they don’t harm or stress wildlife. Pets are not allowed at overlooks, on trails, or in the backcountry, even in carriers. Observe wildlife quietly from a safe distance so as not disturb them. Be Considerate of Other Visitors Avoid disrupting natural quiet with loud music or shouting. Remember— you share public lands with other visitors. Respect and protect the quality of everyone’s outdoor experience. Thank You! Practicing these Leave No Trace outdoor principles is a powerful way to show your love and help preserve public lands for future generations. Have a safe and enjoyable visit by remembering these rules and advisories. Keep off the arches. It’s prohibited—and dangerous—to climb on any arch or on prominent features like Balanced Rock. The sun is intense, and shade is rare. Avoid exertion during peak heat (>90°F /32°C). Protect yourself with sunscreen, sunglasses, and a hat. Do not rely on cell service at Arches. Coverage varies throughout the park. There are pay phones at the visitor center. Emergency? Call 911 Walk on hard surfaces. Stay on trails to protect fragile biological soil crusts and plant and animal habitat, and to reduce your risk of getting lost. Watch your step. Rocks fall. People fall. Sandstone is slippery when wet or icy. In winter, avoid snowy or icy trails. Respect nature. Leave plants, rocks, and artifacts where you see them. Do not feed or disturb animals. Leave drones at home. Launching, landing, or operating unmanned aircraft (such as model airplanes, quadcopters, or drones) is prohibited. Leave the rocks as you see them. Graffiti—carving, scratching, chalking, or any type of marking—is illegal and unsightly. Find your way. Cairns (small rock piles) mark routes. Don’t build your own; they could mislead other hikers. If you get lost, stay where you are, and wait for rescue. Preserve natural darkness. Using artificial light sources to illuminate features for photography at night is prohibited. Do not use ATVs. It’s prohibited to use any type of ATV or OHV. There are many roads outside the park where you can use ATVs and OHVs. Emergencies call 911 National Park Service U.S. Department of the Interior Park Information i HOURS OF OPERATION ` PETS The park is open 365 days a year.

Along the way, hikers encounter another natural wonder, Frame Arch. Also known as Twisted Donut Arch, Frame Arch truly does “frame” Delicate Arch when viewed from just the right angle. Unfortunately, in April 2016 Frame Arch was tragically damaged. “andersen,” deeply chiseled and nearly six feet (1.8 m) in length along the base of Frame Arch was an act of vandalism park staff discovered that spring morning. Vandalism: action involving deliberate destruction of or damage to public or private property. Some American Indians believe, as their ancestors did, that Arches National Park is a sacred place. Some recognize arches as portals in space and time, allowing access to perspectives from the past, present, and future. Today’s technology allows visitors from around the world the opportunity to share moving experiences inspired by visiting Arches National Park. Across cultures, arches are widely treasured. So, for countless park visitors, graffiti applied anywhere in the park is a senseless and selfish act that alters a hallowed place. Graffiti upsets park visitors—and staff too. Some deeply incised graffiti requires the use of power grinding by a skilled operator. But the harm to Frame Arch was too severe. Grinding away a six-footlong, ¾-inch-deep (2 cm) area would have drastically changed Frame Arch, destroying a large portion of what nature took so long to create. Fortunately, treatments to reclaim deep graffiti continue to be developed. Two methods include infilling with a mixture of ground sandstone and an acrylic bonding agent, and in-painting with organic pigments. In October 2017, after studying the damage and carefully matching colors, we began partial infilling and in-painting on Frame Arch. We completed repairs in 2018. We continue to monitor the infilling and may use this same technique in other areas of the park. National parks are places where shared experiences bring people from around the world together. Why do a few people choose vandalism as a park experience? How can the act of defacing geological masterpieces be justified in the mind of one who vandalizes? Regardless of the answer, we require vigilance to mitigate graffiti at Arches. We must act quickly to discourage additional harm by copycat offenders. N P S / C H R I S W O N D E R LY We find graffiti in the park frequently. In October 2017, we began filling some carved graffiti with a mixture of ground sandstone and an acrylic bonding agent. We continue to monitor the filling and may use the technique in other parts of the park. Your involvement is crucial. Choose to leave no trace by not marking on rocks. Talk to friends and family about why graffiti is not OK, and promptly report any violations you witness. Share the Scenery Since 2010, Arches’ visitation has topped 1 million people. The park is popular for good reasons. The breathtaking scenery attracts people from around the world. • • Park staff have been working to manage traffic in the park since 2006. We continue to consider traffic management options, • and are gathering information, data, and analysis to guide future planning. In the mean time, you can use these tips to have an enjoyable experience and to help preserve these timeless landscapes for others to enjoy: B Y M AT T S M I T H • • Start your day early. Enter the park before 8 am. Sunrise is just as beautiful as sunset. Allow extra time. There is plenty of scenery for all to enjoy, and the rocks aren’t going anywhere—at least, not on a human time scale. Carpool. Parking is very limited, so consider leaving extra vehicles, large RVs, or trailers at the hotel, campground, or visitor center parking lot. When parking lots fill, staff may delay vehicle entry for several hours. If the park is too busy, visit other parks and public lands nearby. See page 8 for some options. An Extra Note about Parking During the busy season, you may see rangers assisting in crowded parking lots. Please follow their directions. Acceptable parking places include individually marked stalls, parking “lanes” along fences, and existing turnouts along the roads. Never park on vegetation or in a manner that blocks traffic, and please don’t hold up the flow of cars by waiting for a parking spot. If there isn’t room, move to another area and come back later. Moving forward together, our partnership of shared care and concern can help preserve our national parks and monuments. Hey Kids— This One’s For You! NPS / ANDREW KUHN Do you want to explore Arches and help protect the park? Then become a junior ranger! Becoming a junior ranger is a serious and important task, but it’s lots of fun too. Ask at the visitor center how you can get involved. Options include completing a booklet or checking out a Red Rock Explorer Pack. You’ll earn a badge and certificate and join the ranks of the many junior rangers who help protect this special place.

These bold, playful passerines are one of the most common wildlife sightings in the park. If you’re a “people-watcher” then you may become a “raven-watcher” by the end of your visit; these birds are remarkably like you and me. Like humans, ravens speak their mind. Their sophisticated avian vocabulary is complex with over 30 types of calls. From the low, croak-like “kraaaah” to the deep, nasal “brooonk,” ravens are expressive communicators. Their vocal repertoire includes hunger calls, defense calls, flight calls, alarm calls, whistles, and territorial announcements. These loud-mouthed birds also make nonvocal sounds like wing whistling and bill snapping. The Common Raven can also mimic sounds from their environment including human speech. 6 Arches National Park A Microscopic Community not as social as crows and magpies, their Biological soil crust is a living groundclose relatives, they are often spotted with cover that forms the foundation of or near their mates. high desert plant life in Arches and the surrounding area. Cyanobacteria “Bird brain” isn’t an insult when it comes dominates this knobby crust, but it also to the raven; they actually have large includes lichens, mosses, algae, brains and are extremely intelligent. microfungi, and bacteria. Cognitive processes such as imitation, insight, and the superb ability to solve problems truly set them apart from other bird species. Scientists believe that ravens memorize locations of food sources and have observed ravens using sticks as tools to raid other ravens’ food caches. We humans are not the only species that relies on retaining and recalling past experience as we soar through life. Ravens are opportunists and will eat just about anything they can get their claws on. Most of their diet consists of carrion, lizards, bats, insects, and seeds, but they aren’t opposed to human food as well. These clever scoundrels have been known to break into unsecured coolers and vehicles for tasty yet unhealthy human treats. In an effort to keep wildlife wild, avoid feeding ravens by keeping your food properly stored in a secure location. NPS / ANDREW KUHN Aerial acrobatics, demonstrations of intelligence, and providing food are key behaviors during the courting process. Once paired, ravens nest together for life, usually in the same location. Though B Y M I C H A E L M AT T H E S © TYLER NORDGREN Cyanobacteria, previously called blue-green algae, are one of the oldest known life forms. Scientists think that these organisms were among the first colonizers of Earth’s early land masses, and played an integral role in the formation and stabilization of Earth’s early soils. Extremely thick mats of these organisms converted the planet’s original carbon dioxide-rich atmosphere into one rich in oxygen and capable of sustaining life. When wet, cyanobacteria move through the soil and bind soil particles, forming an intricate web of fibers. The fibers join loose soil particles together, and an otherwise unstable surface becomes very resistant to both wind and water erosion. This soil-binding action does not require living filaments. One can still find layers of abandoned sheaths, built up over long periods of time, clinging tenaciously to soil particles, providing cohesion and stability in sandy soils up to 4 inches (10 cm) deep. Vascular plants can’t utilize nitrogen as it occurs in the atmosphere. Cyanobacteria convert atmospheric nitrogen to a form plants can use. This is especially important in desert ecosystems, where nitrogen levels in the soil are low, which often limits plant productivity. Soil crusts also trap and store water, nutrients, and NPS / NEAL HERBERT organic
