From Boulder Colorado Landmarks & Nature: Adult Coloring Book
Journey to the highest peaks of the Rockies! Discover 10 amazing facts about Colorado, from the Mile High City to ancient cliff dwellings, and learn how to bring these landscapes to life through art.
Welcome to colorful Colorado! Whether you are an outdoor enthusiast, a history buff, or an artist looking for your next muse, this square-shaped state in the American West has something spectacular to offer. Known for its majestic Rocky Mountains, high plains, and arid deserts, Colorado is a land of stunning contrasts and breathtaking elevation.
From the urban energy of Denver to the quiet aspen groves of the high country, Colorado captures the imagination of millions of visitors every year. But how much do you really know about this mountainous region? Grab your hiking boots (and your colored pencils), because we are about to climb into the fascinating history and geography of the Centennial State.
1. Why is it called the "Centennial State"?
Let’s start with the nickname. Colorado is officially known as the "Centennial State." This moniker stems from the year it was admitted to the Union. President Ulysses S. Grant signed the proclamation admitting Colorado as the 38th state on August 1, 1876. This was exactly 28 days after the United States celebrated its 100th birthday—the Centennial of the Declaration of Independence. It was the perfect birthday gift for a growing nation!
2. The Mile High City is Exactly One Mile High
Denver, the state capital and most populous city, isn't called the "Mile High City" just for marketing purposes. It is a geographical fact. The official elevation of the city is measured at the 15th step of the State Capitol building, which sits exactly 5,280 feet (one mile) above sea level.

Denver is a unique blend of urban sophistication and outdoor adventure. It is one of the few places where you can enjoy world-class museums in the morning and hike a mountain trail in the afternoon. For those who love urban sketching, the city offers a stunning skyline set against the backdrop of the Front Range. You can explore the intricate details of the city's unique buildings in our Denver City Landmarks & Architecture: Adult Coloring Book, which captures the spirit of this high-altitude metropolis.
3. Home to the Highest Paved Road in North America
If you love a scenic drive, Colorado takes it to the next level—literally. The Mount Blue Sky Scenic Byway (formerly Mount Evans) is the highest paved road in North America. It climbs up to 14,130 feet above sea level. The drive offers dizzying views of the Continental Divide and the chance to see mountain goats and bighorn sheep grazing near the summit. Just remember to drink plenty of water; the air is thin up there!
4. Pikes Peak and the Garden of the Gods
Located near Colorado Springs, Pikes Peak is perhaps the most famous mountain in America. It was the inspiration for Katharine Lee Bates to write the song "America the Beautiful" after she stood at the summit in 1893.
Just below this towering giant lies the Garden of the Gods, a National Natural Landmark featuring dramatic red sandstone rock formations that jut out of the ground against the blue sky. These ancient rocks, some towering over 300 feet tall, create a landscape that feels almost otherworldly. The contrast of the red rocks, green pines, and white snow-capped peak of Pikes Peak is a favorite subject for artists. You can bring these natural wonders to life with the Colorado Springs Landmarks & Nature: Adult Coloring Book.

5. A State of "Fourteeners"
Colorado has the highest mean elevation of any state in the US. It is famous for its "14ers"—mountain peaks that exceed 14,000 feet in elevation. The state boasts 58 of these majestic peaks, more than any other state. Climbing a 14er is a rite of passage for many locals and visitors.
Among the most photographed of these peaks are the Maroon Bells near Aspen. These twin peaks are reflected in Maroon Lake, creating a scene of perfect symmetry that changes colors with the seasons. Aspen isn't just for skiing; it is a year-round haven for nature lovers. You can escape to these high-altitude sanctuaries from the comfort of your home with the Aspen Colorado Mountain Escape: Adult Coloring Book.
6. The Great Sand Dunes
When you think of Colorado, you probably think of snow. But did you know the state is home to the tallest sand dunes in North America? Located in the San Luis Valley, the Great Sand Dunes National Park and Preserve features dunes that rise up to 750 feet tall. These massive deposits of sand were formed by wind and water over thousands of years, trapped against the base of the Sangre de Cristo Mountains. It is a surreal landscape where you can go sledding on sand in the morning and hike an alpine trail in the afternoon.
7. Boulder and the Flatirons

Just northwest of Denver lies the city of Boulder, a vibrant town known for its university, its pearl street mall, and its incredibly distinct geography. The town is watched over by the Flatirons, massive slanted rock formations that look like old-fashioned clothing irons.
These reddish-brown sandstone formations are the symbol of the city and a playground for climbers and hikers. The interplay of light and shadow on the Flatirons makes them a dynamic subject for art. If you appreciate the mix of college-town culture and dramatic geology, the Boulder Colorado Landmarks & Nature: Adult Coloring Book is a perfect way to explore the area's charm.
8. Ancient History at Mesa Verde
Colorado history goes back much further than the Gold Rush of 1859. In the southwest corner of the state, Mesa Verde National Park protects some of the best-preserved Ancestral Puebloan archaeological sites in the United States.
Famous for its Cliff Palace, a massive dwelling built directly into the cliffside alcove, this site offers a glimpse into the lives of people who lived there for over 700 years, from AD 600 to 1300. It is a UNESCO World Heritage site and a powerful reminder of the deep human history embedded in the landscape.
9. Beautiful State Symbols

To really get to know Colorado, you have to know its symbols.
* State Flower: The Rocky Mountain Columbine. This beautiful white and lavender flower was discovered in 1820. It is illegal to pick them on public land—they are for everyone to enjoy!
* State Bird: The Lark Bunting. While many expect a raptor, this small bird is a native of the plains.
* State Tree: The Colorado Blue Spruce. Known for its silvery-blue needles, it grows throughout the Rocky Mountains.
* State Animal: The Rocky Mountain Bighorn Sheep. These agile animals can be seen scaling steep canyon walls.
10. 300 Days of Sunshine?
It is a popular claim that Colorado gets 300 days of sunshine a year. While climatologists might debate the exact definition of a "sunny day," there is no denying that the state is incredibly bright. Even in the middle of winter, after a heavy snowfall, the sun usually pops out the next day to make the snow sparkle. This abundance of light makes the colors of the landscape—the red rocks, the green pines, the golden aspens, and the blue skies—incredibly vivid.
