Black Canyon of the Gunnison National Park is located in western Colorado, near the city of Montrose. The park was established in 1999 and included approximately 30,750 acres of desert. The Gunnison River is 48 miles long, but only 14 miles through the national park.
The park is known for its incredibly narrow gorges, dug for millions of years by the Gunnison River, which flows into a Precambrian metamorphic rock estimated to be 1.7 billion years old. The high gneiss cliffs and slate leave clear the canyon walls and offer beautiful photos of the stone.
The most famous of these outcrops, the mural, is 685 meters high and is the highest cliff in Colorado. The park takes its name from its cliffs, which often hide shadows and darken the walls.
The canyon itself is so steep that the Gunnison River at this highest point in Chasm View rises at 43 feet per mile and 240 feet per mile, making it one of the steepest descents in North America.
Geologic History of Black Canyon of the Gunnison
The iconic metamorphic rocks were created almost two billion years ago in the Precambrian era when the world was most unstable. Mafic (rich in magnesium and iron) and rocky (rich in feldspar and silica) rocks are buried deep in the ground.
The burial took place with intense heat and pressure, which changed these minerals by freezing and prolonging the crystals and, finally, transforming them into gneiss and metamorphic shales. Bugs, prisons, and other tectonic activities further frustrated rock and created the famous group of dark (poisonous) and light (rocky) gneiss.
Some obscene rocks like pegmatite are also found in canyons, but their appearance is very different from metamorphic rocks. By disrupting volcanic rocks such as pegmatite, the long cooling period of magma, which penetrates into the surrounding rock, allows abundant minerals to form.
In places like the painted wall, magma has a relatively slow cooling rate that crystals can reach up to two meters in length. High elevation and erosion are exposed to deeply formed rocks on the surface. Mining is accompanied by thousands of feet of attrition across the Gunnison River.
After cutting the younger rock strata, the Gunnison River reached the magnificent metamorphic rock below. They are more resistant to erosion than the surrounding sedimentary rocks.
A similar regional survey also led to the Sawatch, West Elk, and the San Juan Mountains, which were dumped in the Gunnison Basin. Only a river with a vast reservoir of high-speed water can be cleared of steep rocks like cliffs when the Black Canyon rises.
The Gunnison River is estimated to have eroded metamorphic rocks at a rate of one inch for 100 years. At this rate, it will take over two and a half million years to erase from top to bottom in painted paint.
Metamorphism at depth
Metamorphosis occurs when heat and pressure change the texture and composition of the original stone. Transformation can occur at different scales. Regional modification generally occurs in large areas, for example, at the limits of plate convergence, where compression forces happen when tectonic plates collide. The gneiss, the rock that forms an integral part of the Black Canyon of the Gunnison, is a high-level metamorphic rock with leaves, the protolith of which originated from granite or slate.
This is my third trip to the Black Canyon of the Gunnison National Park, and this time I can’t wait a few more days. The first two trips were cold, rainy, and windy, but it was still worth it. This time it was warmer, but not sunny enough. It was just a short visit to some of the free moments we spent in Grand Junction.
We stopped by to see again and were always surprised that this place was real. So today, I decided to explain why Black Canyon of the Gunnison is worth visiting for your next trip to Colorado.
Pictures really don’t do it justice
Like the truth, This place looks like a painting, and I still can’t reach it. The only way to understand the depth of the bar is to be there and see for yourself. There may not be hundreds of miles of trails like the Great Smoky Mountains National Park, but the view is more than a walk.
There are countless beautiful places along the spectacular South Rim Tour, so you can see the river flowing below and scream when you hear it from above. I love it.
It’s the least visited national park in Colorado
It means fewer people and more parking for you, I mean, who doesn’t want it? You feel alone there. Magnificent, almost. It is not as big as the Great Sand Dunes, but it is not particularly close to everything the people of Colorado are going to.
It is just over an hour from Grand Junction and well worth a visit. Maybe just check the weather to make sure it’s not too cloudy or rainy. If you have only a chance to visit the park, give it a try because you might get lost. Otherwise, you may have disturbing images.
It’s an International Dark Sky Park
This means that you will have excellent options (see what I did there?). If Bullfrog feels like heaven, make sure you have some time here in the dark. The best way to experience the night sky is to camp in the park, but don’t worry if you are not camping. You can stay in Montrose, the closest city, at any time and drive at dusk to admire the Milky Way in all its glory.
It is excellent if you like intense activities like rock climbing and kayaking.
If you are a kayak expert, this is a great place to go for a drink. The park’s rapids are classified in class V, and some are not managed. It is highly technical and contains many long and risky portfolios. Rafting is not an option in part due to poverty and transportation. Climbing is popular here, but only for experts. Visit the park’s website for more detailed information on the fall of the Black Canyon of the Gunnison.
If it’s not rhythm, don’t worry. There are still many tours, and you can even go fishing in the river. Have a nice trip.
