Denver was officially settled on November 22, 1858; its coordinates are 39.7392° N, 104.9903° W. As of 2026, the city’s population is estimated at 735,000, with the Denver-Aurora-Lakewood metro area home to over 2.9 million people.
What’s Denver’s geographic story?
Denver sits in the Front Range of the Rocky Mountains, right where the High Plains meet the peaks. That spot where Cherry Creek flows into the South Platte River? That’s what made it such a natural meeting point—first for trade routes, then for railroads and highways. The elevation ranges from about 5,280 feet at the Colorado State Capitol to just over 5,300 feet downtown, which is why Denver earned the nickname “Mile High City.” Its location also put it on a historic path for Indigenous travel, westward expansion, and early farming settlements.

Any interesting background on Denver’s early days?
Long before Denver existed, the Cheyenne and Arapaho peoples used the South Platte River valley for seasonal hunting and gathering. Spanish explorers wandered through in the late 1500s, but permanent European settlement didn’t happen until gold turned up along the South Platte in the 1850s. On November 22, 1858, General William Larimer staked his claim and named the place “Denver City” after Kansas Territory Governor James W. Denver. Within months, thousands of prospectors—the “Fifty-Niners”—poured in during the Pike’s Peak Gold Rush. By 1861, Denver became the capital of the new Colorado Territory. The arrival of the railroad in 1870 sealed its fate as a major commercial hub, linking the mining West with the agricultural Great Plains.
Geologically, the Denver Basin formed from sediments piled up over millions of years, including layers packed with dinosaur fossils. Stegosaurus bones found near Morrison prove Denver sits in one of North America’s richest Late Jurassic fossil beds. Today, Dinosaur Ridge preserves some of the world’s most accessible dinosaur tracks and bones.
What should visitors know about getting around Denver?
Denver International Airport (DEN) sits 25 miles northeast of downtown and offers nonstop flights to over 200 destinations. The Regional Transportation District (RTD) runs buses and light rail that connect downtown with suburbs like Aurora, Lakewood, and Westminster. Denver basks in over 300 days of sunshine a year, with mild winters and warm summers—but don’t be surprised by sudden temperature swings. Top spots include the Denver Art Museum, Red Rocks Park and Amphitheatre, and the historic Union Station. As of 2026, Denver’s transit system ranks among the most reliable in the West, though most people still drive thanks to the metro’s sprawling layout. After the post-pandemic price surge, home values have settled around $610,000 as of mid-2026.
What was the first settlement in Colorado?
Fort Bent
When did the first people arrive in Colorado?
The first Europeans to explore Colorado were the Spanish, who came looking for gold in the sixteenth century. Hispanic Americans started settling in the San Luis Valley in the 1840s, making them the earliest non-Indigenous residents.
What was Colorado’s original name?
Jefferson Territory, which later became the State of Colorado, was established around the same time as Denver City. Early proposals for the territory’s name included Colona, Osage, and Idaho.
How long ago was Colorado underwater?
About 92 million years ago, nearly all of Colorado was underwater. A hundred million years back, the landscape was a flat sandy beach with rivers flowing into the ocean.
What dinosaur bones have been found in Colorado?
Stegosaurus (Colorado’s state dinosaur), Apatosaurus (originally called Brontosaurus), Diplodocus, and Allosaurus—these big names put Colorado on the map as the first state west of the Mississippi where nearly complete skeletons of large dinosaurs were discovered.
What civilization thrived in Colorado long ago?
Ancestral Pueblo culture, also called Anasazi, flourished from roughly AD 100 to 1600, centered where modern-day Arizona, New Mexico, Colorado, and Utah meet.
Can shark teeth be found in Colorado?
Shark teeth, bryozoans, bivalves, cephalopods, and other marine fossils dating back over 300 million years have turned up in parts of Colorado. Early conifer fossils like Walchia show up too.
Can you find Megalodon teeth in Colorado?
Nope—unlike Florida, where they’re everywhere, Colorado doesn’t have the right conditions for Megalodon teeth to turn up in parks or beaches.
Where are trilobites found in Colorado?
The Manitou Formation (Manitou Dolomite) is the main trilobite hotspot. This Lower Ordovician layer is mostly limestone, dolomite, and red dolomite.
Are there dinosaur tracks in Colorado?
Yes—head to Picketwire Canyon in La Junta for a 11.2-mile round-trip hike to the largest dinosaur track site in North America. The Comanche National Grasslands in southeastern Colorado hold a 150-million-year-old snapshot of the past.
What dinosaur had 500 teeth?
Nigersaurus
Did T. rex live in Colorado?
A few scattered T. rex teeth were found near Golden, Colorado, back in 1874.
Where did dinosaurs live in Colorado?
Dinosaur Ridge
What kinds of dinosaurs lived in Colorado?
Stegosaurus roamed Colorado during the Late Jurassic Period (155 to 145 million years ago). Some of the most important Stegosaurus discoveries have been made here, which is why it became the state fossil.
Did dinosaurs live in the Rocky Mountains?
Eventually, the Rockies rose high enough to push the sea back, opening up vast inland territory for dinosaurs to roam. That shift slowed how quickly new species evolved in the region—new species popped up only every few million years.
