Walnut Canyon National Monument is a United States National Monument located about 10 mi southeast of downtown Flagstaff, Arizona, near Interstate 40. The canyon rim elevation is 6,690 ft; the canyon's floor is 350 ft lower.
Come gaze across curved canyon walls. Among the remarkable geological formations of the canyon itself, the former homes of ancient inhabitants are easily evident. Along the trails you can imagine life within Walnut Canyon, while visiting actual pueblos and walking in the steps of those who came before.
Walnut Canyon National Monument is located approximately 7.5 miles (12 km) east of Flagstaff. From Interstate 40, take Exit 204, and turn south. The Walnut Canyon Visitor Center is located at the end of this 3-mile (5 km) road.
Walnut Canyon Visitor Center
The visitor center features architecture from both the Civilian Conservation Corps and the Mission 66 era. The visitor center is the starting point for all visits to Walnut Canyon and is staffed daily by park rangers. Children may pick up Junior Ranger activities here.

Inventory and Monitoring Data Help Flagstaff Area National Monuments Meet Resource Management Challenges
From inventory data, to long-term monitoring data sets, to special projects, Southern Colorado Plateau Network data on vegetation communities, wildlife, and hydrology has informed much of the work being done in the network’s 19 parks.

The Colorado Plateau
The Colorado Plateau is centered on the four corners area of the Southwest, and includes much of Arizona, Utah, Colorado, and New Mexico.

Southern Colorado Plateau Exotic Plant Inventory
Exotic plants take a heavy toll on biodiversity around the world. In the United States, exotic plant species invade tens of thousands of hectares every year, outcompeting native species and causing many to become threatened or endangered. Fire, flood, and other natural disturbance regimes can also be altered by exotic plants, broadly affecting land management.

Wildland Fire in Douglas Fir: Western United States
Douglas fir is widely distributed throughout the western United States, as well as southern British Columbia and northern Mexico. Douglas fir is able to survive without fire, its abundantly-produced seeds are lightweight and winged, allowing the wind to carry them to new locations where seedlings can be established.

Walnut Canyon NM Headquarters Area Historic District Cultural Landscape
The Walnut Canyon Headquarters Area Historic District is part of Walnut Canyon National Monument, located southeast of Flagstaff in Coconino County, Arizona. The layering of features makes the Walnut Canyon Headquarters Area a significant example of projects completed during early conservation efforts in the United States—most notably the “New Deal” era of the 1930s‑1940s and the “Mission 66” era of the 1950s‑1960s.

Wildland Fire in Ponderosa Pine: Western United States
This forest community generally exists in areas with annual rainfall of 25 inches or less. Extensive pure stands of this forest type are found in the southwestern U.S., central Washington and Oregon, southern Idaho and the Black Hills of South Dakota.

Vegetation Characterization and Mapping on the Southern Colorado Plateau
Vegetation mapping is a tool used by botanists, ecologists, and land managers to better understand the abundance, diversity, and distribution of different vegetation types across a landscape.

Climate Change on the Southern Colorado Plateau
The combination of high. elevation and a semi-arid climate makes the Colorado Plateau particularly vulnerable to climate change. Climate models predict that over the next 100 years, the Southwest will become warmer and even more arid, with more extreme droughts than the region has experienced in the recent past.
One result of climate change may be more, larger floods, like this flash flood in Glen Canyon NRA

Series: Geologic Time Periods in the Paleozoic Era
During the Paleozoic Era (541 to 252 million years ago), fish diversified and marine organisms were very abundant. In North America, the Paleozoic is characterized by multiple advances and retreats of shallow seas and repeated continental collisions that formed the Appalachian Mountains. Common Paleozoic fossils include trilobites and cephalopods such as squid, as well as insects and ferns. The greatest mass extinction in Earth's history ended this era.

Series: Defining the Southwest
The Southwest has a special place in the American imagination – one filled with canyon lands, cacti, roadrunners, perpetual desert heat, a glaring sun, and the unfolding of history in places like Tombstone and Santa Fe. In the American mind, the Southwest is a place without boundaries – a land with its own style and its own pace – a land that ultimately defies a single definition.
Maize agriculture is one component of a general cultural definition of the Southwest.

Substitute Rangers
As the 1940s dawned, the United States was still dealing with the economic woes of the Great Depression and trying not to get drawn in WWII. Even as it continued to manage New Deal Program work in national and state parks, the NPS remained understaffed as a government bureau. The emergency relief workers and about 15 percent of NPS staff enlisted or were drafted during the first couple of years of WWII.

Find Your Park on Route 66
Route 66 and the National Park Service have always had an important historical connection. Route 66 was known as the great road west and after World War II families on vacation took to the road in great numbers to visit the many National Park Service sites in the Southwest and beyond. That connection remains very alive and present today. Take a trip down Route 66 and Find Your Park today!

Changing Patterns of Water Availability May Change Vegetation Composition in US National Parks
Across the US, changes in water availability are altering which plants grow where. These changes are evident at a broad scale. But not all areas experience the same climate in the same way, even within the boundaries of a single national park. A new dataset gives park managers a valuable tool for understanding why vegetation has changed and how it might change in the future under different climate-change scenarios.

Studying the Past and Predicting the Future Using Rat Nests
In the western United States, packrat middens are one of the best tools for reconstructing recent environments and climates. These accumulations of plant fragments, small vertebrate remains, rodent droppings, and other fossils can be preserved for more than 50,000 years. Packrat middens have been found in at least 41 National Park Service units.

Series: Geologic Time—Major Divisions and NPS Fossils
The National Park System contains a magnificent record of geologic time because rocks from each period of the geologic time scale are preserved in park landscapes. The geologic time scale is divided into four large periods of time—the Cenozoic Era, Mesozoic Era, Paleozoic Era, and The Precambrian.

50 Nifty Finds #17: Common Threads
Each National Park Service (NPS) employee has a unique story. We can't tell them all, but sometimes there's a personal account—like that of Sallie Pierce Brewer Van Valkenburg Harris—that speaks to common experiences. Although her NPS connections ran from 1933 to 1971, many of her joys, challenges, and frustrations can still be recognized in the NPS today. Sallie's story resonates regardless of era, gender, or position. How will it speak to you?
