The Leave No Trace Seven Principles are the bedrock of the Leave No Trace program. They provide guidance to enjoy our natural world in a sustainable way that avoids human-created impacts. The principles have been adapted so they can be applied in your backyard or your backcountry. More information at www.lnt.org/

Unique combinations of geologic color and erosional forms decorate a canyon that is 277 river miles (446km) long, up to 18 miles (29km) wide, and a mile (1.6km) deep. Grand Canyon overwhelms our senses through its immense size.
The story of how Grand Canyon came to be begins with the formation of the layers and layers of rock that the canyon winds through. The story begins about 2 billion years ago when igneous and metamorphic rocks were formed. Then, layer upon layer of sedimentary rocks were laid on top of these basement rocks.
The Kaibab Limestone, the uppermost layer of rock at Grand Canyon, was formed at the bottom of the ocean. Yet today, at the top of the Colorado Plateau, the Kaibab Limestone is found at elevations up to 9,000 feet.
Uplift of the Colorado Plateau was a key step in the eventual formation of Grand Canyon. The action of plate tectonics lifted the rocks high and flat, creating a plateau through which the Colorado River could cut down
The way in which the uplift of the Colorado Plateau occurred is puzzling. With uplift, geologists generally expect to see deformation of rocks. The rocks that comprise the Rocky Mountains, for example, were dramatically crunched and deformed during their uplift. On the Colorado Plateau, the rocks weren’t altered significantly; they were instead lifted high and flat.
The Colorado River has been carving away rock for the past five to six million years. Remember, the oldest rocks in Grand Canyon are 1.8 billion years old.
Geologists call the process of canyon formation downcutting. Downcutting occurs as a river carves out a canyon or valley, cutting down into the earth and eroding away rock.

Follow the paths where ancient native people and pioneers walked. Gaze up at massive sandstone cliffs of cream, pink, and red that soar into a brilliant blue sky. Experience wilderness in a narrow slot canyon. Zion’s unique array of plants and animals will enchant you as you absorb the rich history of the past and enjoy the excitement of present day adventures.
When you enter Zion National Park you will experience a feeling that won’t quite fit inside your camera. Your eyes will search to take it all in; your voice will falter as you try to express the emotion. The only place you’ll truly comprehend it is in your heart. Zion will change you, from the inside out. The colors will astound you. The perspective will humble you.
Leave No Trace is a national program that protects the outdoors by teaching and inspiring people to enjoy it responsibly. The seven principles of Leave No Trace promote responsible outdoor recreation through education, research, and partnerships. Leave No Trace is dedicated to building awareness, appreciation, and most of all, respect for our public lands.
Established in 1972, Buffalo National River flows freely for 135 miles and is one of the few remaining undammed rivers in the lower 48 states. Once you arrive, prepare to journey from running rapids to quiet pools while surrounded by massive bluffs as you cruise through the Ozark Mountains down to the White River in central Arkansas.
The Ozark Mountains are known to have one of the largest karst networks in the midwest United States. The Buffalo National River alone has more than 500 caves within its boundaries, making it one of the most cave-rich units in the National Parks. Karst systems are a type of topography that typically forms in contact with carbonate rock units of limestone and dolomite.
You can find additional geological information about the park on the NPS Fieldnotes page at https://nature.nps.gov/geology/parks/buff/index.cfm
The challenge for 2019 will be to complete 100 miles of physical activity on any public lands within the state of Arkansas. This means any activity you do in an Arkansas National Park, Arkansas State Park, US Forest Service site, National Wildlife Refuge site, Army Corps of Engineers site, or city park can be counted. Activities include walking, running, hiking, biking, and paddling. So get out there and enjoy your public lands!
The Buffalo River flows freely for 151 miles. Typically, the float season begins on the upper Buffalo in the spring. More water makes this section attractive for visitors seeking a higher level of challenge with whitewater kayaking. The season moves downstream with the months, varying from month to month with rainfall. Unlike rivers that are fed by perennial springs, the Buffalo is largely rainfall dependent. In dry years, the floating season is short and quickly moves down into the Middle and Lower Districts. In wet years use of the upper river is prolonged with floating opportunities spread out through the park for the entire season.

Wilderness areas are set aside by our nation's leaders because of their unique opportunities for solitude, mental and physical challenge, and spiritual enrichment. Those who venture into Wilderness must plan ahead and be adequately prepared with appropriate skills and equipment.To preserve the wilderness experience and character, all visitors should be familiar with Leave No Trace principles and practice them while traversing Buffalo National River. It is also essential to have a realistic understanding of your abilities before entering Wilderness
Buffalo National River has nearly 36,000 acres of designated Wilderness within its boundaries. Three Wilderness areas—the Upper Buffalo Wilderness, Ponca Wilderness, and Lower Buffalo Wilderness—make up more than one-third of the land area of this park unit, and each Wilderness has its own unique story.
General Information: Always check weather and water levels before and during your trip. Heavy or prolonged rains, which may occur upstream and out of sight, can raise river levels rapidly. Rises of over a foot an hour can occur at any time of the year, and the river can rise more than 25 feet in a single day. If an emergency situation occurs, visitors should not depend on cell phones as cell service is very limited along the river. In case of emergency contact the park's 24-hour dispatch center, Midwest Region Ozark Communication Center (MROCC), at 1-888-692-1162.
