What is one interesting fact about the Sunset Crater?
Sunset Crater in northern Arizona is one of the youngest volcanoes in the USA. It is named for its brilliantly colored scoria deposits on the cone and only one of more than 550 vents of the vast San Francisco volcanic field. The last eruption took place sometime between about 1080 and 1150 AD.
How was the Sunset Crater formed?
Sunset Crater is a colorful volcanic cone composed of lava fragments called cinders. It was created when molten rock spewed from a crack in the ground, high into the air, solidified, then fell back as cinders or ash. Over the next 200 years, the heavier debris accumulated around the vent creating the 1,000-foot cone.
Why is Sunset Crater called Sunset Crater?
Sunset Crater, a basaltic cinder cone in the San Francisco Volcanic Field, Arizona, erupted in 1085 A.D. (Credit: Brugger-Schorr, Carrie. Public domain.) Sunset Crater erupted about 1085 A.D. The cone is named for the topmost cap of oxidized, red spatter, which makes it appear bathed in the light of the sunset.
Has Sunset Crater killed anyone?
No evidence has been found that people died as a direct result of the eruption, so it seems there was enough warning for people to evacuate from their homes. After the eruption, pithouses for miles around were burned and filled with cinders, and others were buried beneath the lava.

What type of volcano is Sunset Crater?
cinder cones
The San Francisco Volcanic Field Sunset Crater Volcano is one of around 600 cinder cones in the Flagstaff area. This is a region of intense volcanism that began around 3 million years ago with the formation of a lava dome called Bill Williams Mountain.
How old is the Sunset Crater?
Is Sunset Crater an active volcano?
Sunset Crater Volcano, part of the San Francisco Volcanic Field, is an extinct cinder cone. Sunset Crater Volcano erupted over 900 years ago, making it the youngest cinder cone in a field of over 600 volcanoes. It is now extinct and not anticipated to erupt again.
Is Sunset Crater active?
Can you climb Sunset Crater?
Though you can’t climb Sunset Crater, you can walk up to the top and even inside a cinder cone when you take the trail on Lenox Crater. The 1.6-mile round trip to the top of the crater consists of a trail that’s shaded by tall ponderosa pines and features switchbacks on black sand and lava pebbles.
Is Sunset Crater still active?
Local cinder cones are created by a one-time eruption event and are not known to erupt more than once. Sunset Crater Volcano erupted over 900 years ago, making it the youngest cinder cone in a field of over 600 volcanoes. It is now extinct and not anticipated to erupt again.
How big is the Sunset Crater Volcano?
900 square miles
The eruption and formation of Sunset Crater Volcano incinerated the surrounding landscape, covering almost 900 square miles (2300 square km) with lava and ash.
What kind of volcano is the Sunset Crater?
Sunset Crater is a cinder cone volcano. Among the smallest of the volcanoes, a cinder cone erupts gently, spewing small globs of lava that cool into volcanic pebbles called cinders. Over the course of the eruption, cinders pile into a steep-sided cone, forming a deep crater around the volcano’s vent. Cinder cones are also known as scoria cones.
What to expect at Sunset Crater in Arizona?
And so do human visitors, intrigued by this opportunity to see natures response to a volcanic eruption. Arizona’s Sunset Crater Volcano reshaped the nearby landscape, and now offers hiking, scenery of flora like Ponderosa Pines, and an array of wildlife. When visiting Sunset Crater Volcano, prepare for extreme weather conditions.
Is it possible for Sunset Crater to erupt again?
No. Sunset Crater is extinct and will not erupt again. However, there is still an active magma chamber (underground pool of molten rock) under the area, which will undoubtedly produce more eruptions in the future. These eruptions will produce brand new cinder cone volcanoes, some of which might even form right next to Sunset Crater.
How old is Sunset Crater and Meteor Crater?
Sunset Crater is an extinct volcano, while Meteor Crater is a meteorite impact site 40 miles southeast of Sunset Crater. The one-mile wide, 550 foot-deep crater is about 50,000 years old (once again, young by geologic standards) and is the best-preserved meteorite impact site on Earth.
