Lybrook Fossil Area is a colorful, stark spectrum of earth tones, ranging from yellow, brown, pink, and purple to stark, tall hills of layered black and white. It is a cornucopia of peculiar rock formations, including tall spires, hoodoos, towering caprocks, and other bizarre geologic specimens.

The Kasha-Katuwe Tent Rocks in New Mexico is a magical place. Cone-shaped tent rock formations from volcanic eruptions over 6 million years ago.

Looking upward at the cone-shaped tent rock formations with blue sky above. The rugged rocks reveal lines or layers that are the products of volcanic eruptions that occurred 6 to 7 million years ago and left pumice, ash, and tuff deposits over 1,000 feet thick. Tremendous explosions from the Jemez volcanic field spewed pyroclasts (rock fragments), while searing hot gases blasted down slopes in an incandescent avalanche called a pyroclastic flow. Precariously perched on many of the tapering hoodoos are boulder caps that protect the softer pumice and tuff below. Some tents have lost their hard, resistant caprocks, and are disintegrating. While fairly uniform in shape, the tent rock formations vary in height from a few feet up to 90 feet. https://www.blm.gov/visit/kktr Looking toward the vista of cone-shaped tent rock formations with blue sky above.

A complex badlands terrain showing deeply eroded pinnacles, hoodoos and steep-sided faces composed of mudstone and harder caprocks. A myriad of whimsical figures may be imagined. The sky is featureless.

A pair of irregularly-shaped hoodoos stand atop a low ridge of mudstone under a deep blue sky with scattered clouds. The caprocks atop these rock formations are an iron-red sandstone, with hundreds of smaller ironstone pebbles scattered on the hillside below.

A huge red boulder takes up the lower-right portion of this image, with a group of disorganized hoodoos uphill and behind. The basal rock is heavily-eroded mudstone of a lighter hue than the red caprocks.

A diverse collection of landforms is visible in this single view, with the central rock formation having a sphinx-like shape. At left are several towering flowstone features, while the pinnacles at right have caprocks of stratified deposition. Here, sandstone takes many forms.

...and speaking of hoodoos, here's a fine stocky fellow who appears to be gazing with disapproval or contempt at the #scape at large.

The image is dominated by a bulky sandstone monument in the center of the image - it wears a cap of ironstone and appears to have its arms folded before it. Several other, lesser, ironstone caprocks are scattered about the ground, while the shaded area to the left suggests the presence of another towering feature out of frame.

A towering, three-pronged mudstone pinnacle overlooks a desolate flatland with low hills in the distance at left. The layers that make up the pinnacle are clearly stratified, with two of the three peaks bearing caprocks. There is scattered ironstone debris at the foot of the promontory.

Nah, the methane will most likely stay below the reservoirs' caprocks and should stay underground imo.

Thanks! It really is a wild area. In the nearby De-Na-Zin, there is a remote canyon where some stones have been weathered into perfect giant spheres and those have also become caprocks on hoodoos. I will show those later.

I don't know why that abstract refers to the Cap Rock Member of the Ogallala when Bob Differendal had a paper years ago saying you can't distinguish it in Nebraska, there are multiple cemented "caprocks" in the Ogallala there.

Assessing Caprock Sealing via Breakthrough Pressure Tests
In a groundbreaking study published in Environmental Earth Sciences, researchers have unveiled new insights into the sealing capabilities of caprocks used in underground gas storage facilities. The study addresses a critical challenge in the energy sector: ensuring the long-term containment of gases stored deep beneath the Earth’s surface. By exploring the breakthrough pressures of caprocks under complex stress conditions, this research provides an advanced understanding of how subterranean geological formations behave when subjected to dynamic stress paths, which is vital for safe and efficient underground gas storage.

I photographed these geological shapes of Kasha-Katuwe Tent Rocks National Monument, a protected public landscape located about 40 miles southwest of Santa Fe, New Mexico.
Origin: Pyroclastic flows deposited thick layers of pumice, ash, and tuff following massive explosive volcanic eruptions from the Valles Caldera volcanic field roughly 6 to 7 million years ago.Shape: Over millennia, wind and water eroded the soft material away, forming distinctive cone-shaped formations called hoodoos or tent rocks. Caprocks: Many cones retain a harder stone caprock on top, protecting the softer rock beneath from crumbling under the weight of overhead rain.

The unique landscape in my photo is the Kasha-Katuwe Tent Rocks National Monument in northern New Mexico. The name "Kasha-Katuwe" translates to "white cliffs" in the Keresan language of the Cochiti Pueblo.
The cone-shaped formations you see are called hoodoos or tent rocks. They are the result of volcanic eruptions from the Jemez volcano six to seven million years ago, which left behind thick layers of pumice and tuff. Over millions of years, wind and water eroded these softer volcanic materials, often leaving behind harder "caprocks" that protect the underlying rock, creating distinct tower shapes that can reach up to 90 feet tall.
