Description: "Looks Like A Bird" Well, it was one more case of pareidolia as I wandered around the Cannonball Concretions area in the North Unit of Theodore Roosevelt National Park. The formation on the left looks like a perched bird to me.

Description: "Cannonball Concretion" There were many concretions in this area of Theodore Roosevelt National Park in the North Unit. Many were irregular shapes, but this one is a sphere, and it made me understand why this area was named Cannonball Concretion! National Park in North Dakota. I condensed some information I read: As iron carbonate dissolves in groundwater, it forms around a fragment in the rock, such as a leaf, shell, bone, or fossil. The iron compound grows around this nucleus, and a concretion begins. As water and wind erode the calcite-bonded sandstone, concretions appear as spheres, pipes, or irregular shapes that are often harder than the surrounding sedimentary rock.

Description: "What Is Inside That Opening" The dark area in the upper middle looked like an open door to me.

Description: "Ring-billed Gulls at the Spillway" I go to the Great Salt Plains State Park in northern Oklahoma often. My main reason is for birdwatching, and normally, I make my first stop at the spillway. Why? Because there will almost always be some birds standing on one of the tiers where the water flows over and down to the river below. The morning light gives the water a nice color and provides reflections as well. ©Debra Martz, All Rights Reserved In My Collection: "Feathered Friends" 2026-02-25-_DSC0607 AI Text: Two seagulls glide gracefully over the reflective surface of the water.

Description: "Eroded Cliffside and Rock Formations" Erosion is the main shaping force of the badlands of North Dakota. On this cliffside, harder layers create rust-colored shelves that, in turn, help protect the softer gray sediments beneath. Desert-like plants such as Sagebrush and Junipers grow in several areas on the hillside and at the base along the trail. And in the Cannonball Concretions area, you will see unique, hardened shapes known as concretions, which first form inside layers of sedimentary rock, often around something like a small rock, leaf, or shell. As more mineral-rich water flows through the area, the sediments bind together like glue, becoming larger and larger over time. An example of a concretion lies in the lelft light gray area
Description: "Badlands Differential Erosion" Differential erosion is the main shaping force of the badlands of North Dakota. Harder layers create shelves that, in turn, help protect the softer gray sediments beneath. Desert-like plants such as Sagebrush grow in several areas on the hillside and at the base along the trail.

Description: "Otherworldly Rock Formations" Not far into the drive, I called out to stop the truck. These formations were right along the side of the road, but no pullout anywhere near. Approaching these eroded rocks, I thought it looked like a lineup of people, then thought of a choir standing, or were they spooky goblins? None of those descriptions were anywhere in the brochure; actually, this sight was not even mentioned or shown on the map we were given at the entrance. Such was the beginning of the North Unit of Theodore Roosevelt National Park that I knew we had a good day of scenic adventures ahead. ©Debra Martz, All Rights Reserved 20250806-DSC_2963 AI Text: Natural erosion has sculpted unique formations in the rock face.

Description: "Rocky Embrace" Since I was young, I would always watch the clouds to find shapes and faces. As time went on, I would see things in all forms of nature. Here I see two rock figures standing next to each other, and they appear to have arms around each other's shoulders, giving me the title of "Rocky Embrace" for this image. Pareidolia, they call it...can you see it? This was found in the Cannonball Concretions area of the North Unit of Theodore Roosevelt National Park. It was a favorite stop of mine in this unit, walking the trail near so many unusual rock formations.

Description: "Bright Pink Spherical Flower" Is it a Shameplant? I was at the start of a trail to do some birdwatching when I saw this bright pink flower. Not sure what it was, so later I used an ID app, which revealed that it was known as Mimosa pudica, aka the Shameplant. Mimosa pudica goes by many names: The Sensitive Plant. The Shy Plant. Touch Me Not. The Tickle-Me Plant. The Sleepy Plant. The Humble Plant. All of its names stem from the plant's response to stimulus: when it is touched, its leaves fold up and its branches droop. ©Debra Martz, All Rights Reserved 20251017-DSC_9135 AI Text: A vivid pink flower stands out against a blurred natural background.
