Building A Legend

Red Rocks Park has evolved from a phenomenon of nature to one of the world’s most beloved performance venues. The Vision and perseverance it took to achieve this transformation is a remarkable piece of Denver history.

Early Days In the Park
Before John Brisben Walker purchased the Park of the Red Rocks in 1906 and renamed it the Garden of the
Titans, it had long been known to visitors as the Garden of the Angels. Tourists would travel to Morrison on the railroad, walk west through town to the Gateway Stables and hire burros to take them through the rocks and up for a picnic at the natural amphitheater. This photo probably dates from after 1916, by which time Denver businessman John Brisben Walker had purchased the land that makes up today’s park and developed it as a tourist attraction. He built a funicular railway to the top of Mount Morrison and charged 60 cents for park admission. In 1927, the City of Denver purchased the property from him for $54,133.

The Trading Post: A National Historic Landmark
You are standing in the historic Trading Post, designed by architect W.R. Rosche. Constructed in 1931, it was designed in the Pueblo Revival style to reflect indigenous architecture from the American Southwest and to harmonize with the surrounding landscape. It was a popular first stop for mountain park visitors in the early days of automobile touring, offering a nature museum, lunch counter, and gift shop to Denver citizenry exploring the Colorado mountains.

Ancient Inspiration for Ancient Rocks
The ancient Greek amphitheater at Taormina, on the southern Italian island of Sicily, was Denver Parks manager George Cranmer’s inspiration for the theater at Red Rocks. It was built by Greek colonists in the third century BC and reconstructed by the Romans five centuries later.

Before: The boulder-strewn field filled the area between Creation Rock and Ship Rock before Civilian Conservation Corps crews moved over 50,000 cubic feet of earth and rock debris. The project took 5 years.

After: A dedication concert on June 15, 1941, featured an organist, the Denver Municipal Chorus and Orchestra, and a performance by world famous Metropolitan Opera star Helen Jepson, along with many speeches.

The Men of CCC Camp SP-13-C, Company No. 1848 – Artisans of the Amphitheatre
The Civilian Conservation Corps (CCC) put to work thousands of young men across Depression-era America, most notably in constructing trails, bridges, and other amenities in public parks. Supervised by army officers and local craftsmen, they earned food, clothing, shelter, and $30 a month — $25 of which was sent home to their families.

“I predict that someday thousand people will assemble there to listen to the world’s greatest masterpieces.” – Opera singer Mary Garden, 1911

Beyond Competition
Red Rocks is as highly respected as a concert site by promoters and artists as it is by audiences. The amphitheatre won first-place award among performance venues so many times in Pollstar,
the professional journal of concert promotion, that Pollstar finally removed Red Rocks from competition and named the award the “Red Rocks Award.”

On August 4, 2015, Red Rocks Park and Mount Morrison Civilian Conservation Corps Camp were designated as a National Historic Landmark. This designation recognizes the national significance
of Red Rocks Park in architecture, landscape architecture, and performing arts. Many consider this another ‘Golden Age’ for Red Rocks as it hosts more events and visitors than any other time in its
history.

If Rocks Could Talk

Distinctive rock shapes: Water, ice, and wind slowly transform the rocks, depending on their hardness. But vertical cracks can form suddenly when layers collapse or lightning strikes.

Gauging age: How can you tell if a crack is ancient or recent? What secrets does the lichen hold?

Crevices create habitat: Smooth hard sandstone resists weathering, so horizontal crevices often form in weaker layers above or below. Look up to see how plants (and
animals) take advantage of these ledges. The uniform blocky layers can be deposited quickly, as by floods.

Cool condos for birds: Rushing water carries larger pebbles and scrapes mudballs from streambanks. Pebbles drop to form bands of conglomerate, but the
mudballs quickly weather out, leaving rock shelters used by birds and small animals.

What made the Sphinx’s neck?
Soft mudstone weathers quickly, leaving indents between more durable sandstone layers. Sometimes bizarre shapes such as this beautiful Sphinx form. What might eventually happen to the Sphinx’s head?

Picture a different world
You are standing on the Foundation Formation, a 300-million-year-old rock formation. Long before the dinosaurs, an earlier mountain range, called the Ancestral Rockies, rose to the west.

Strange scale-trees such as Lepidodendron and Sigillaria occupied wetlands along streams. Tree ferns covered the slopes of foothills nearby.

An ancient mammal-like reptile, Dimetrodon was 6 to 15 ft (2 to 4 m) long, one of the largest land predators of Late Paleozoic times, when these sediments were deposited.

These red rocks, known as the Fountain Formation, are more than 1,000 feet (300 m) thick. Look closely to see coarse red sand layers and deep purple mud layers, reflecting the fall and rise of water levels along the coastline.

Why are the rocks red?
“Redbeds” like these were deposited around the world between 300 and 260 million years ago. High levels of oxygen in the air reacted with the iron in the sediments washed from the mountains, making the rocks look rusty. More than that, the extra oxygen supported giant insects! Today, oxygen levels are too low to form redbed deposits. Where else in Colorado can you see rocks like these? (By the way, ‘Colorado’ means ‘red’!)

The Naming of Rocks

Through time and imagination, these rocks have been named and often renamed. Red Rocks is full of “gateway” rocks and others that have been compared to ships, or named for their parks, caves, and other features. Cracks become crevices, then enlarge to grottos, caves, and labyrinths, inspiring fanciful names like Fat Man’s Misery or Demon’s Grotto.

Early in the 1900s, when J.B. Walker named his park Garden of the Titans, many of the features were named after those ancient Greek gods, including Rock of Cronus, Rock of Mnemosyne, Cave of Saturn, Spring of Rhea, and Rock of Tethys.

What is a Park? A grassy open space within a large outcrop is often called a park. Nine Parks Rock has nine of these gardens. Can you spot miniature parks on the rocks nearby? These spots are where moisture collects, plants grow, and animals find islands of habitat among the barren rocks.

REMEMBER: ROCK CLIMBING IN RED ROCKS PARK IS PROHIBITED!
Climbing on these rocks is extremely dangerous, and can be deadly. Rock climbing anywhere in the park is strictly prohibited.

Ranger Hiking Tips In Red Rocks Park

Be prepared

  • Wear appropriate hiking attire for the current season and bring plenty of water and sunscreen.
  • Plan your hike ahead of time and know when it gets dark.
  • If coming from a lower altitude, avoid overexertion.

Keep wildlife wild

  • Stay on the trail and respect wildlife habitat.
  • If you encounter a snake or any other wildlife, back away.

Leave what you find

  • Leave plants, rocks, and other natural features where you find them for others to enjoy.
  • Rocks in the park are millions of years old. Climbing rocks is prohibited.
  • Pack out all trash and dog waste.
  • Help us minimize human impact.

Rock Dwellers

When you head out for a scenic day hike, look closely at the rock formations for signs of birds and other wildlife who may be nesting, napping, or tending to their young. White stains on the rock can be a sign of bird activity.

Peregrine Falcon
Capable of diving for prey at 250 mph, the peregrine is considered one of the fastest animals on earth.

Cliff Swallows
Nesting in the rocks or soaring high above the trail, watch for these graceful flying acrobats.

Bobcat
Stealthy and adept, these cats share the park with mountain lion, bear and fox.

Snakes

Look Twice: Bullsnake or Rattlesnake?
Snakes play a vital role in the park ecosystem by controlling population of rodents and insects, which helps maintain balance in the food web.

They serve as both predator and prey, supporting a variety of species including raptors and mammals. While several species of snakes call Red Rocks home, snake sightings are a rare treat. Visitors are most likely to encounter the bullsnake or prairie rattlesnake, which look similar.

Bullsnakes are not dangerous. They will bite if provoked, but they are non-venomous.

  • They have a narrower, rounder head that is about as wide as the neck.
  • They may mimic rattlesnakes by shaking their striped tail to fool predators.

Prairie rattlesnakes may be dangerous, but they are not aggressive and will not attack humans unless provoked.

  • Their triangular-shaped head is substantially wider than the neck. Heat-sensing “pits” (indentations) between the eyes and nostril help locate prey.
  • They have a distinctive rattle at the end of the tail which they sometimes shake as a waring. Older snakes often have longer rattles.

Ranger Tip
If you see a snake in the wild make sure to give it plenty of space and leave it alone! Never try to touch or pick up a snake. Stay on the trail to avoid unexpected encounters.

Nature's Music (Listen)

Canyon Wren
The canyon wren’s distinctive call can be heard echoing throughout the park.

Mexican Free-Tailed Bat
The Mexican Free-Tailed bat uses high-pitched clicks and squeaks to communicate and locate insects.

Mormon Cricket
The Mormon cricket is a variety of katydid that makes a rapid chirping sound by rubbing its forewings together.

Peregrine Falcon
The peregrine falcon has multiple vocalizations, including wailing and a kak-kak! sound warning enemies that they should leave.

Elk
During the fall mating season, the male elk make loud bugling and grunting sounds to attract female elk and advertise their dominance to other males.

Great-Horned Owl
The great-horned owl has a deep stuttering call that sounds similar to “ho hoo hoo hoododo hooo ho.

Rattlesnake
The rattlesnake’s hollow tail rattles when shaken signifying danger to any who venture too close.

Listen
Red Rocks has long been a haven for music lovers. But wait! What about the music being made, day and night, all around the amphitheatre? Coyotes, birds, insects, and other music-makers all take the stage throughout the seasons and around the clock.

“I am enchanted by a tiny bird with a voice that rivals the greatest singers on the amphitheatre stage.” – Doris Cruz, past president of the Audubon Society of Greater Denver speaking about the Canyon wren.

Twilight Creatures

Crepuscular Creatures
Masters of Dawn and Dusk 

Creatures such as raccoons, bats, foxes, and owls are most active during twilight making them crepuscular! This behavior has evolved to avoid daytime predators, resulting in bigger eyes and wider pupils for excellent nighttime vision. To best avoid predation, many twilight critters have unique adaptations to stay silent while moving. From extra padded paws to stealth wings, the best crepuscular critters are the very quiet ones.

Ranger Tip
Raccoons are especially active at Red Rocks. Avoid littering trash and do not feed them.

The shape of the pupil tells a story. What’s yours?

Bear
Large predatory animals like this bear as well as lions, wolves and humans, have round pupils. When located on the front of the head, round-pupil eyes allow for good binocular depth perception and a large amount of light to enter–helpful for hunting both day and night.

Deer
Prey animals, like this deer and other grazing animals, have horizontally elongated pupils, often located on the sides of their head. These allow prey animals to see sharp images ahead and behind, and creates a horizontally panoramic view to effectively detect predators.

Fox
Ambush predators, like this fox and the domestic cat, have vertically elongated pupils, and are likely to be active day and night. Their forward facing slit-shaped pupil adjusts quickly to low light, and aids the predator in judging distance from prey.
