Blue Mesa Trail: a 1-mile hike through badlands and petrified wood

The Blue Mesa Trail in Petrified Forest National Park, Arizona, is a 1-mile loop trail that takes hikers through a valley of multicoloured badlands and fossilised wood. The trail is relatively easy, with benches along the path, although there is a slightly moderate finish as you ascend from the badlands. The trailhead is located halfway around the loop road at a sunshelter.

The Blue Mesa Trail offers an immersive encounter with the region's geology. The journey begins with a descent into a valley, where hikers encounter sweeping panoramas of the multicoloured badlands. These clay hills, rich in mineral deposits, display a spectrum of hues that shift with the light. The blue, purple, grey, and peach banded badlands are a spectacular sight. The funky shapes of the badlands are amazing, but it is the striated mineral rainbow that makes these formations unforgettable. The trail, though paved, is pretty narrow and bumpy, so it is not suitable for strollers.

Along the route, interpretive panels are placed to provide insights into the geological history of this area and the powerful natural forces that sculpted this extraordinary landscape. The unique formations and fossilised wood contribute to an experience that connects visitors with both the past and present of this captivating environment. Chunks of contrasting, brightly-coloured petrified wood can be found tucked in crevices and out in the open spaces.

The Blue Mesa is a significant landform located on a spur road halfway through Petrified Forest National Park. The road is around 5 miles round trip and goes on top of the mesa with scenic overlooks of the landscape, badlands, trail, and hoodoos. The mesa consists of the Blue Mesa and Sonsela Members with petrified wood deposits.

Mesas are isolated, flat-topped hills or mountains with steep sides. They are formed through the process of differential erosion, where less resistant rock layers are worn away while the more resistant caprock remains. Mesas can be found in various arid regions around the world, including the American Southwest, Australia, and the Middle East. The size of mesas can vary significantly, ranging from vast areas of 350 square kilometers (140 square miles) to smaller formations of just 0.1 square kilometers (0.039 square miles). The flat tops and steep sides of mesas create different environments that support a wide range of ecosystems and wildlife.

The Painted Desert: a desert of badlands with brilliant and varied colours

The Painted Desert is a desert of badlands in the Four Corners area of the United States, spanning about 120 miles (190 km) in length and 60 miles (100 km) in width, with an area of roughly 7,500 square miles (19,420 square km). It is characterised by its brilliant and varied colours, including common red rock shades and rarer hues of lavender. The desert gets its name from Spanish explorer Francisco Vázquez de Coronado, who passed through the area during his 1540 quest to find the Seven Cities of Cibola. He named the area "El Desierto Pintado", which translates to "The Painted Desert".

The Painted Desert is located in Arizona, running from near the east end of Grand Canyon National Park southeast into Petrified Forest National Park. The desert is known for its colourful collection of petrified wood, as well as its multihued mesas of stratified layers of mudstone, shale, and siltstone pigmented by iron and magnesium deposits. These mesas, with their flat tops and steep sides, offer stunning views of the surrounding desert and mountains. They are formed by the weathering and erosion of horizontally layered rocks, which creates their distinctive shape. The resistant rock types that make up mesas include sandstone, conglomerate, quartzite, basalt, chert, limestone, lava flows, and sills.

One notable mesa within the Painted Desert is Blue Mesa, located on a spur road halfway through Petrified Forest National Park. Blue Mesa offers spectacular views of blue, purple, gray, and peach banded badlands. The Blue Mesa Trail is a popular hiking trail that takes visitors through these colourful badlands and petrified wood deposits. The trail is moderately strenuous, paved, and gravelled, stretching for about 1 mile (1.6 km).

In addition to Blue Mesa, there are other notable mesas in the Painted Desert, such as Black Mesa and Horseshoe Mesa in Grand Canyon National Park. Black Mesa, the second-largest plateau, offers breathtaking views and trails, while Horseshoe Mesa showcases the unique shape formed by erosion. The Painted Desert Rim Trail is another popular trail that provides remarkable views of the Painted Desert, including panoramic vistas of red, orange, pink, and purple rocks from Kachina Point.

The Painted Desert has a cold desert climate, with hot, dry summers and chilly, snow-free winters. The annual precipitation in the region is among the lowest in northern Arizona. The desert is accessible through major highways and paved roads, with the towns of Cameron and Tuba City, both on the Navajo Nation, being two major settlements.

Grand Canyon National Park: home to the second-largest plateau, Black Mesa

The Grand Canyon National Park is home to the second-largest plateau, Black Mesa. A mesa is an isolated, flat-topped elevation, ridge, or hill, bounded by steep escarpments and standing above a surrounding plain. They are formed by the weathering and erosion of horizontally layered rocks that have been uplifted by tectonic activity. This process, known as differential erosion, results in the distinctive shape of mesas, with their flat tops and steep sides.

Black Mesa is located in the heart of Arizona, within the Grand Canyon National Park. It offers breathtaking views and trails for visitors to explore. The Grand Canyon National Park also boasts another notable mesa, Horseshoe Mesa, known for its unique shape that showcases the power of erosion.

The Painted Desert, a United States desert of badlands, is located in the Four Corners area, extending from near the east end of Grand Canyon National Park to the Petrified Forest National Park. This desert is known for its brilliant and varied colours, including the more common red rock and shades of lavender. The Painted Desert was named by a Spanish expedition led by Francisco Vázquez de Coronado in 1540.

Within the Painted Desert, Blue Mesa stands out as a significant landform. It is located on a spur road halfway through the Petrified Forest National Park. Blue Mesa offers spectacular views of blue, purple, gray, and peach-banded badlands. The mesa consists of the Blue Mesa and Sonsela Members with petrified wood deposits.

Petrified Forest National Park: the world's largest collection of colourful petrified wood

Arizona's Petrified Forest National Park is a destination for those seeking otherworldly landscapes. The park covers about 346 square miles (900 square kilometres) and is known for its fossils, colourful badlands, and one of the world's largest collections of colourful petrified wood.

The park is located in Navajo and Apache counties in northeastern Arizona. The park's headquarters is about 26 miles (42 km) east of Holbrook, with the BNSF Railway's Southern Transcon, the Puerco River, and historic U.S. Route 66 crossing the park roughly east–west. The park received 644,922 recreational visitors in 2018, and its elevation above sea level varies from 5,340 feet (1,630 m) to 6,230 feet (1,900 m), with an average elevation of about 5,400 feet (1,600 m to 1,650 m). The terrain varies from gentle hills to eroded badlands and major petrified wood deposits.

The petrified wood in the park comes mainly from tall conifers that grew more than 200 million years ago along waterways, where periodic flooding uprooted trees. The downed trees were buried by sediment containing volcanic ash, and groundwater dissolved silica (silicon dioxide) from the ash, carrying it into the logs and forming quartz crystals that replaced the organic matter. Traces of iron oxide and other substances combined with the silica to create the varied colours in the petrified wood. The park contains vast, colourful, and well-preserved deposits of petrified wood, with exceptionally large deposits in five areas termed "forests".

The park offers scenic views of the landscape, badlands, trail, and hoodoos. The Blue Mesa trail, located halfway around the loop road, provides access to the top of the mesa and overlooks the colourful badlands. The park is also home to a diverse range of wildlife, including more than 16 kinds of lizards and snakes, seven types of amphibians, and various plant species.

The Petrified Forest National Park is a significant site for understanding the ecosystem of the Late Triassic Epoch, with its large deposits of petrified wood and fossils of early dinosaurs, plants, and other animals. The park was designated a national monument in 1906 and a national park in 1962 to preserve its scientific value and protect its unique resources.

Mesas: isolated, flat-topped hills or mountains with steep sides

A mesa is an isolated, flat-topped elevation, ridge, or hill, surrounded by steep escarpments and standing distinctly above a surrounding plain. Mesas are formed by the weathering and erosion of horizontally layered rocks that have been uplifted by tectonic activity. This process, known as differential erosion, results in the wearing away of softer rocks, leaving behind harder rock tops. The resistant rock types that often form the flat tops, or caprock, of mesas include sandstone, limestone, basalt, lava flows, and sills. These rock types are very resistant to weathering and erosion.

Mesas can vary significantly in size, ranging from vast areas of 350 square kilometers (140 square miles) to smaller formations of just 0.1 square kilometers (0.039 square miles). They are found in various arid regions around the world, including the American Southwest, Australia, and the Middle East. In Arizona, the Painted Desert, located within the Petrified Forest National Park, is known for its brilliant and varied colors, including red rocks and shades of lavender. The Blue Mesa Trail in the Painted Desert offers scenic views of the landscape, badlands, trail, and hoodoos.

The mesa landforms in Arizona's Monument Valley have become a symbol of the American West. These sandstone formations, shaped by wind and water, stand tall in the desert and offer opportunities for hiking, driving, and guided tours. Black Mesa and Horseshoe Mesa in Grand Canyon National Park are other notable mesas in Arizona, providing breathtaking views and trails. Canyonlands National Park in Utah is also home to mesa landmarks that attract visitors from around the world.

While there may not be a specific size limit that distinguishes mesas from other landforms, their distinct flat tops and steep sides create unique environments that support diverse ecosystems. The dry lands around mesas support drought-resistant plants and trees, which provide food and shelter for animals such as bighorn sheep, coyotes, and birds of prey. The vertical walls of mesas are particularly appealing to rock climbers, offering thrilling challenges that test their strength and agility.

In summary, mesas are isolated, flat-topped hills or mountains with steep sides, found in various arid regions worldwide. They are formed by differential erosion, leaving behind harder rock tops. The Painted Desert in Arizona showcases the beauty of mesas with its vibrant colors and scenic views. Arizona's Monument Valley and Canyonlands National Park in Utah also feature prominent mesas that have become symbols of the American West.
