Leave No Trace Principles

Arizona Climbing and Adventure School (ACAS) is a supporting partner of LNT. ACAS practices and instructs in Leave No Trace Principles and philosophy of outdoor ethics:

1. Plan Ahead and Prepare
2. Travel and Camp on Durable Surfaces
3. Dispose of Waste Properly
4. Leave What You Find
5. Minimize Campfire Impacts
6. Respect Wildlife
7. Be Considerate of Other Visitors

Plan Ahead and Prepare
• Know the regulations and special concerns for the area you'll visit.
• Prepare for extreme weather, hazards, and emergencies.
• Schedule your trip to avoid times of high use.
• Visit in small groups. Split larger parties into groups of 4-6.
• Repackage food to minimize waste.
• Use a map and compass to eliminate the use of marking paint, rock cairns or flagging.

Travel and Camp on Durable Surfaces
• Durable surfaces include established trails and campsites, rock, gravel, dry grasses or snow.
• Protect riparian areas by camping at least 200 feet from lakes and streams.
• Good campsites are found, not made. Altering a site is not necessary.

In popular areas:
• Concentrate use on existing trails and campsites.
• Walk single file in the middle of the trail, even when wet or muddy.
• Keep campsites small. Focus activity in areas where vegetation is absent.

In pristine areas:
• Disperse use to prevent the creation of campsites and trails.
• Avoid places where impacts are just beginning.

Dispose of Waste Properly
• Pack it in, pack it out. Inspect your campsite and rest areas for trash or spilled foods. Pack out all trash, leftover food, and litter.
• Deposit solid human waste in catholes dug 6 to 8 inches deep at least 200 feet from water, camp, and trails. Cover and disguise the cathole when finished.
• Pack out toilet paper and hygiene products.
• To wash yourself or your dishes, carry water 200 feet away from streams or lakes and use small amounts of biodegradable soap. Scatter strained dishwater.

Leave What You Find
• Preserve the past: examine, but do not touch, cultural or historic structures and artifacts.
• Leave rocks, plants and other natural objects as you find them.
• Avoid introducing or transporting non-native species.
• Do not build structures, furniture, or dig trenches.

Minimize Campfire Impacts
• Campfires can cause lasting impacts to the backcountry. Use a lightweight stove for cooking and enjoy a candle lantern for light.
• Where fires are permitted, use established fire rings, fire pans, or mound fires.
• Keep fires small. Only use sticks from the ground that can be broken by hand.
• Burn all wood and coals to ash, put out campfires completely, then scatter cool ashes.

Respect Wildlife
• Observe wildlife from a distance. Do not follow or approach them.
• Never feed animals. Feeding wildlife damages their health, alters natural behaviors, and exposes them to predators and other dangers.
• Protect wildlife and your food by storing rations and trash securely.
• Control pets at all times, or leave them at home.
• Avoid wildlife during sensitive times: mating, nesting, raising young, or winter.

Be Considerate of Other Visitors
• Respect other visitors and protect the quality of their experience.
• Be courteous. Yield to other users on the trail.
• Step to the downhill side of the trail when encountering pack stock.
• Take breaks and camp away from trails and other visitors.
• Let nature's sounds prevail. Avoid loud voices and noises

The UIAA is the International Mountaineering and Climbing Federation. In the spirit of sport and friendship it brings together nearly three million men, women and children joined by their passion for mountains. As a global community of volunteers, our members exchange ideas, give guidance and work together on the following areas:
• Lobbying for the opportunity for everyone to responsibly access the world’s special and beautiful mountain environment. 
• Giving young people the opportunity to overcome differences and form friendships across borders and cultures – building a peaceful and better world through sports.
• Preserving mountain environments for the good of all by supporting local communities to achieve sustainable development and respect nature.
• Providing reliable safety standards for climbing equipment and advice on medical issues related to mountaineering. 
• Organising competitions in ice climbing with the ultimate aim of competing in the Winter Olympic Games. We fight doping.

The UIAA was founded in 1932. It started as a European organisation, but now all continents are represented with 90 member organisations from 62 different countries. The UIAA is recognised by the International Olympic Committee as the international federation for mountaineering.

Since 1964 climbers have been able to look for the UIAA Safety Label when they buy climbing equipment. The label means that products have been tested to the highest standards. Since 2004 the UIAA has also awarded the Environment Label to those who follow UIAA environmental guidelines when organising activities in the mountains.

Protection of the mountain environment is a central issue to the UIAA. In order to keep mountains free for rubbish and pollution caused by visitors it is necessary that everyone involved in mountaineering activities do their part. Unfortunately not everybody who organises mountaineering activities take the necessary steps to protect fragile mountain environments. Therefore we created the UIAA Environment label, which can be awarded to providers of organised activities such as a training centre, trekking or expedition organisation, qualified instructor or guide.

The UIAA want to make it easier for you to make the right choices when you are looking for someone to take you out in the mountains. When you see the UIAA Environment label, you know that the people who organise your trek or expedition have committed themselves to acting according to the UIAA’s Environmental Objectives and Guidelines.
