What is special about Black Canyon of the Gunnison?
Black Canyon is home to the fastest bird in the world, the Peregrine falcon. Scientists estimate that Peregrines can reach speeds of over 200 mph in an aerial dive. Poison ivy is abundant at the bottom of Black Canyon. It can grow over 5 feet tall along the Gunnison River.
What type of rock is the Black Canyon of the Gunnison?
Gneiss, the rock that makes up a significant portion of the Black Canyon, is a high-grade, foliated metamorphic rock whose protolith was originally granite or schist.
What is unique about the Black Canyon?
The Black Canyon Is Over 2,700 Feet Deep 1 For comparison, Hells Canyon in Idaho and Oregon is the deepest canyon in North America at just over 8,000 feet. Black Canyon is unique in that it is much narrower, ranging from 1,000 feet to as narrow as 40 feet.
What rock is Black Canyon made of?
The steep, “black” walls of Black Canyon are composed of Precambrian granites, gneisses, gabbros, diorites, pegmatites, and schists. The canyon itself is considered one of the best exposures of these ancient rocks in the world. Directly atop the Precambrian rocks, lie Mesozoic and Cenozoic sedimentary strata.
How was Gunnison canyon formed?
About 30 million years ago, large volcanoes erupted on either side of this uplift, burying it in volcanic rock (blow). Then, as early as 2 million years ago, the Gunnison River began flowing in force (flow). The river and time eroded all of the volcanic rock and cut a deep canyon in the metamorphic rock below.

Why is the Grand Canyon such a valuable site for geologists studying the history of the changing earth?
Because the Canyon so clearly lays out many layers of the earth’s crust, geologists from around the world have been drawn here, many making important scientific discoveries and changing the way that people understand our planet, how it was formed and how it continues to change.
Why is it called the Black Canyon?
The Black Canyon, so named because the walls are often shrouded in shadows making them appear black, has some of the world’s oldest exposed rock — Precambrian or “basement” rock that is nearly 2 billion years old.
How did Black Canyon became a national park?
Creation of the park The Black Canyon of the Gunnison was established as a national monument on March 2, 1933, and was redesignated a national park on October 21, 1999. During 1933-35, the Civilian Conservation Corps built the North Rim Road to design by the National Park Service.

Is Black Canyon of the Gunnison deeper than the Grand Canyon?
Depth (feet) of the Black Canyon at Warner Point. That’s impressive, but not by comparison to the true monsters. Hells Canyon, the deepest canyon in North America, is 7,913 feet deep at Hedevil Point (on the Idaho side). The Grand Canyon averages about 5,000 feet deep.
What’s the biggest canyon on earth?
Kali Gandaki Gorge in Nepal is the world’s largest canyon in the world. Sandwiched between the Himalayas, the Kali Gandaki Gorge of Nepal is surrounded by the imposing mountains of Annapurna and Dhaulagiri, rising up for more than 8,000 m over the gorge.
Why is the Grand Canyon important to geologists?
Geology in the Grand Canyon attracts the attention of the world for many reasons, but perhaps its greatest significance lies in the geologic record preserved and exposed here. The rocks at Grand Canyon are not inherently unique. Similar rocks are found throughout the world.
What is the geology of the Grand Canyon?
Grand Canyon’s Rock Layers Sedimentary rocks form the middle and top layers of Grand Canyon. Layers of sediment hardened into sedimentary rocks over time. Most of the canyon’s igneous and metamorphic rocks make up the bottom layers of Grand Canyon, near the Colorado River. Igneous rocks formed when liquid magma cooled.

What type of geological feature is the Grand Canyon?
In the Grand Canyon, unconformities are common in the Grand Canyon Supergroup and the Paleozoic Strata. The three main types of rock are igneous, sedimentary and metamorphic. Igneous rocks are cooled magma (melted rock found underground) or lava (molten rock found above ground).
