Black Canyon of the Gunnison National Park was shaped by powerful forces over millions of years. The canyon formed as the Gunnison River cut through layers of rock, including some rocks that are nearly 2 billion years old. Uplift, volcanoes, erosion, and weathering all helped create the deep, narrow canyon we see today.

Gunnison Uplift: About 70 million years ago, a large block of land called the Gunnison Uplift was pushed upward. This exposed very old rocks that had formed deep underground. These rocks are mostly gneiss, schist, and other hard rocks. They are nearly 2 billion years old.

Ancient River: The Gunnison River has been flowing through this region for millions of years. Scientists believe the modern river course was established about 10 to 15 million years ago. The river first cut through softer volcanic and sedimentary rocks before reaching the much harder rocks below.

Erosion: About 2 million years ago, the Gunnison River began cutting into the hard rocks of the Gunnison Uplift. The river carried sand, gravel, and other materials that slowly wore away the rock. The river continues to shape the canyon today.

Hard Rock and Deep Cliffs: Much of the canyon is made of hard rocks that resist erosion. Because these rocks wear away slowly, the canyon has kept its steep, narrow shape. The Gunnison River drops about 43 feet for every mile through the canyon, giving it strong cutting power.

Volcanic Activity: Volcanoes formed north and south of the Gunnison Uplift millions of years ago. They covered parts of the area with thick layers of volcanic ash and rock. The Gunnison River later eroded much of this softer material as it carved the canyon. The last major volcanic eruptions in the nearby area ended about 18 million years ago.

Tectonic Activity: Movements of Earth's crust helped raise the Gunnison Uplift and bring the ancient rocks closer to the surface. These forces were an important part of the canyon's history. Erosion, weathering, and the Gunnison River continue to change the canyon today.

Black Canyon Today: Black Canyon is about 48 miles long, with about 14 miles inside the national park. Its deepest point is about 2,722 feet. The Gunnison River continues to slowly carve the canyon, showing that the landscape is still changing.

Black Canyon of the Gunnison has a long Native American history. The Ute people have strong historical and cultural connections to the region, and Indigenous people have used the lands around the canyon for thousands of years.

Ancient Use: People have lived in and traveled through the area around Black Canyon for thousands of years. They hunted animals, gathered plants, and used natural materials from the land. The canyon and nearby areas provided food, water, shelter, and other useful resources.

The Ute People: The Ute people have a long history in western Colorado, including the area around Black Canyon. Different Ute bands traveled across the region to hunt and gather food. The canyon was part of a larger landscape that was important to their way of life.

Cultural Connections: The landscape around Black Canyon has cultural importance to Indigenous peoples. However, specific beliefs, stories, or ceremonies connected to the canyon are not always known or publicly shared. It is important to avoid assuming that the canyon was considered a sacred place without evidence.

Rock Art and Archaeology: Archaeological sites in the region provide evidence of Indigenous use of the area. These sites can include tools, campsites, and other objects that help researchers learn about the people who lived here. Some rock art is also found in western Colorado, but individual sites should not be connected to a specific tribe without evidence.

Hunting and Gathering: Indigenous people used the land around Black Canyon to hunt animals and gather plants. Deer, elk, and other animals provided food and materials. Plants were also collected for food, medicine, and other uses.

Travel Through the Region: Indigenous people traveled across the lands around the canyon as they moved between hunting and gathering areas. However, the steep walls and narrow passages of Black Canyon made travel through the canyon itself difficult.

Euro-American Contact: During the 1800s, increasing numbers of Euro-American explorers, miners, and settlers entered western Colorado. This brought major changes for the Ute people and other Indigenous communities. The U.S. government later forced many Ute people from their traditional lands and onto reservations.

Continuing Connection: Native American history is an important part of the story of Black Canyon of the Gunnison. The Ute people and other Indigenous communities continue to have connections to western Colorado. Learning about these connections helps visitors better understand and respect the history of the park and the surrounding region.
