The Three “R”s of Folding Time
Grand Canyon Style
By Leigh Anderson
There is a place—like no other in the world—where time seems to fold in on itself. Where the past meets the here-and-now, mountains meet oceans, beauty meets danger, and discovery meets mystery. This place is the Grand Canyon.
The Grand Canyon is 277 river miles long. At certain points, it’s more than a mile deep and as much as 18 miles wide. Going 50 miles per hour, it would take over five hours to drive its entire length! At such speed, you’d hardly see any of what makes the canyon truly grand: dazzling, glittering colors; fossils and wildlife; a great river snaking through . . . rock; and many-layered canyon walls giving glimpses of Earth’s history.
Geologists1 have many, different . . . [ideas] about how and when the Grand Canyon was formed. The story of the canyon’s beginnings is like a jigsaw puzzle with many pieces missing. There are a few things geologists do agree on. We’ll call them the three “R”s: Rocks, River, and ‘Rosion (actually, Erosion,2 but we’re going to cheat a bit!).
Rocks
The Grand Canyon’s walls are made up mainly of three types of rock: limestone, sandstone, and shale. Over . . . [thousands of] years, the rock built up layer by layer. Each new layer of rock pressed down on the layers beneath it. Then the Colorado River began to cut through these layers like a knife, exposing them for us to see. At the Grand Canyon today, 18 or more layers of Earth’s history are laid out for us to see. We can see backward in time! The rocks near the top of the canyon are . . . [very] old, but those toward the bottom of the canyon are . . . [thought to be over six times older]. What an amazing place for scientists to study the history of Earth.
Limestone, sandstone, and shale: Each of these types of rock was formed in a different way. Limestone is made from the fossilized skeletons of tiny organisms that lived in ancient seas. (Fossils are the super hard remains of plants or animals . . .) Sandstone is actually sand, pressed so hard over . . . [thousands of] years that it stuck together into rock. And shale is basically mud, left over from the bottoms of ancient lakes and marshes. Some rock is softer, some is harder, and they erode at different rates. When a layer of hard rock is on top of a layer of softer rock, amazing cliffs are created. . . .
River
Without the Colorado River, there would be no Grand Canyon. The river flows southwest from the Rocky Mountains to the Gulf of California, crossing through an area called the Colorado Plateau. As it flows, the river crosses Colorado, Utah, Arizona, and Nevada before flowing into Mexico and the Gulf. But the ancient Colorado was not the same river we know today. In fact, long ago it was probably more than one river. When those ancient rivers joined, the newly formed Colorado began flowing southwest. It bucked over dangerous rapids and frothed like chocolate milk in a blender as it carried mountains of dirt downstream. Like sandpaper repeatedly rubbing the same piece of wood, the fast-moving, sand-filled water slowly carved a groove in the rock beneath it.
But the Colorado River didn’t carve the canyon by itself. As ancient glaciers melted, the river and its tributaries3 flooded again and again. The floods cleared away the sand, gravel, and other sediment at the bottom of the river. Then, rocks and boulders, which had tumbled into the river, were able to grind and scrape the bedrock at the river’s bottom, further deepening the canyon.
As water moves through the canyon, it flows “downhill,” dropping in elevation. This makes the water flow faster, with more power to carve out the rock. Also, long ago, the land around the Colorado River began to rise bit by bit, bubbling upward like a giant blister. Known as uplift, this process continued over . . . [many] years. Uplift helped form the canyon we know today.
What Do You Think? The Colorado River Today
Today, the Glen Canyon and Hoover Dams tightly control the Colorado River. The river now runs more slowly. Floods no longer sweep away the sediment at the bottom of the river. The river-bottom sediment is 75 feet deep in some places! Because of the slower water and the thick “blanket” of sediment, the carving of the canyon has slowed down. . . .
‘Rosion
When rain falls on rocks, water seeps into the cracks in the rock. When the weather gets cold and that water freezes, it expands, or gets bigger. Over and over, water freezes and expands in the cracks. And slowly, the rock splits apart. Pieces of broken rock (from tiny to huge) fall into the canyon below. As they fall, they might hit another rock and send it tumbling too. When they finally reach bottom, some rocks are carried away by the Colorado. Others remain where they landed.
Heavy rains send great slabs of sediment, mud, and rock crashing down cliff faces, widening the canyon and carving new shapes into the giant red walls. The Colorado’s tributaries are busy, too, carving smaller side canyons. Sometimes these side canyons erode into each other, further widening the canyon. This is all part of the process of rocks, river, and ‘rosion that makes this canyon so GRAND!
1geologists: people who study rocks, minerals, and soils of the earth or a particular area
2erosion: a process by which rock, soil, or sand is gradually worn away by water, wind, or ice
3tributaries: smaller rivers and streams that flow into a larger river

**The Grand Canyon: A Journey Through Time and Nature**
In a land where the earth's beauty is raw and unrefined, the Grand Canyon reigns supreme. It stands as a monument to both nature's magnificence and its relentless passage of time. My expedition began at dawn, when the sun's first rays spilled over the distant peaks, illuminating the vibrant hues of the canyon walls. The air was crisp, laden with the earthy aroma of sagebrush, and the gentle whisper of the Colorado River flowed beneath me. As I stood at the precipice, the sheer drop made my heart race, yet the breathtaking panorama captivated me. This is a place where one feels both infinitesimally small and profoundly connected to the larger tapestry of existence.
As daybreak painted the landscape with strokes of gold, I descended into the canyon, sharing the path with a diverse ensemble of characters: fellow adventurers, families eager to delve into nature, and solo travelers seeking solace in the wild. Among them was Sarah, a spirited nature enthusiast, constantly in search of the next thrilling story hidden among the rocks, and James, a stoic geologist, his rugged hands tracing the many layers of sedimentary rock exposed along our trail. Their stories intertwined with my own, each voice echoing with awe at the Grand Canyon's grandeur. Together, we became witnesses to the echoes of history written in stone.
Midway through our trek, the true conflict of the journey emerged—not merely with the demanding terrain, but within ourselves. Each twist in the trail urged us to confront our deepest fears: the challenge of our physical limits, the wild unpredictability of nature, and the passage of time itself. I vividly recall the moment when the clouds thickened, casting shadows that danced across the canyon, reminding me of life’s uncertainties. The wind howled through the crevices, lifting both the dust and our spirits, each gust propelling us forward. I felt an exhilarating mix of vulnerability and strength as we navigated steep cliffs, sharp rocks, and the narrow paths alongside gushing rapids.
As we paused for breath at a ledge overlooking an expansive view, I took in the erosion patterns carved into the canyon walls, visible proof of the relentless forces of nature. I marveled at the centuries-old whispering rocks that might have watched civilizations rise and fall. Here, geology and ecology narrated tales of ancient seas teeming with life, cannibalistic glaciers that shaped the landscape, and the mighty Colorado River that acted as both artist and architect transforming stone into majesty.
Ultimately, we emerged back at the rim as the sun dipped below the horizon, casting an ethereal glow. With the last rays of sunlight illuminating the canyon, it was clear that this expedition had transformed us. We were no longer mere explorers; we had become stewards of this grand metaphor for life itself—a reminder of resilience, change, and the beauty of impermanence. We left the canyon not just with stories but with a deeper understanding of our own stories woven into the vast narrative of the earth.
Leaving the Grand Canyon behind was bittersweet, yet I couldn’t shake the deep connection I felt to the place. I had ventured into the heart of a natural wonder and returned with insights woven into the tapestry of nature, and through every layer of rock, I discovered pieces of myself. In its folds, I learned not just about geology and erosion, but about life—a journey through time and a reminder that we are all part of an unfolding story, just like the magnificent Grand Canyon itself.
