Due to the erosional powers of wind and water over thousands of years, the soft sediments of the Santa Fe Formation were carried away. Without any support beneath it, the heavy basalt caprock broke and collapsed over the side, creating today’s West Mesa escarpment or edge.
What formed the mesas in New Mexico?
The Frijoles Canyon and mesas, which include the Bandelier National Monument, are part of the Pajarito Plateau, which was formed over a million years ago from powerful volcanic eruptions. Over time, the erosion-formed canyons, including Frijoles Canyon, were home to Ancestral Pueblo peoples for many years.
What formed the rock formations in New Mexico?
Six to seven million years ago, a period of intense volcanic activity from the Jemez Volcanic Field resulted in “pyroclastic flows”, that being avalanches of rock fragments and hot gases, and the deposition of pumice and ashes, forming a layer nearly 1,000 feet thick.
What caused mesas to form?
Mesas are formed by erosion, when water washes smaller and softer types of rocks away from the top of a hill. The strong, durable rock that remains on top of a mesa is called caprock. A mesa is usually wider than it is tall. Mesas are usually found in dry regions where rock layers are horizontal.
How were the New Mexico mountains formed?
Southern Rocky Mountains • North Central New Mexico
These mountains were formed by the folding and faulting of the North American continent about about 80 to 55 million years ago (around the same time as the end of the Age of Dinosaurs).
Why is New Mexico so rocky?
The north central section of New Mexico is covered by a series of mountain ranges that are part of the Rocky Mountains. The Rio Grande River cuts through the Rocky Mountains from north to south. East of the Rio Grande, is the Sangre de Cristo (Blood of Christ) Mountain range.
Why are mesas flat on top?
Combined with strong winds, these heavy rains erode the softer sedimentary layers over time. As a result of this type of erosion, mesas end up as tall landforms with steep sides and wide, flat tops. The top, durable layer (called cap rock) remains while the softer rock along the sides erodes away over time.
What is unique about New Mexico?
Two of New Mexico’s most unique physical features are the caverns near Carlsbad, which are among the most spectacular natural rock formations in the world, and the extensive gypsum sand dunes at White Sands National Monument in south-central New Mexico, which were created by wind and water erosion.
How long does it take to form a mesa?
Its north side rises nearly 2,000 feet (610 meters) above the valley below. Over millions of years, erosion has carved out the sides of the mesa. Overhangs and alcoves have developed where sections of softer sandstone layers have broken away. Mesa Verde is perhaps more noted as a cultural landscape.

What is Lava mesa?
Lava flows and sills, in particular, are very resistant to weathering and erosion, and often form the flat top, or caprock, of a mesa. The less resistant rock layers are mainly made up of shale, a softer rock that weathers and erodes more easily.
