Powerful explosions profoundly affected the lives of the local population and forever changed the landscape and ecology of the area. 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. Sunset Crater, one of the youngest scoria cones in the contiguous United States, began erupting between the growing seasons of 1064 and 1065 A.D. Eruptions continued in the area for many decades. How did Sunset Crater form? Sunset Crater is an extinct volcano, while Meteor Crater is a meteorite impact site 40 miles southeast of Sunset Crater. Unlike Sunset Crater, there is a paved road to the top of this volcano. 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 moon’s surface is riddled with craters ranging in size and structural complexity, and billions of years ago before life emerged, the Earth looked the same way. The cone was named by John Wesley Powell, first director of the U.S. Geological Survey, for the topmost cap of oxidized, red spatter which makes it appear bathed in the light of the sunset. The ground shook periodically, trembling more and more as the days passed until, finally, the earth was split wide open by an eight-mile-long crevice.
I did not understand what a cinder cone was but fortunately The Sunset Crater website explained it. When did Sunset Crater form? “The bottom line is, everything that happened on the moon happened on the Earth,” said David Kring, crater expert and team leader for Center for Lunar Science and Exploration. Sunset Crater is a colorful volcanic cone composed of lava fragments called cinders. Asked by Orion Wisoky. It was sunny, but cold and a bit windy, when we rolled into the visitor center parking lot. The field … Sunset Crater, one of the youngest scoria cones in the contiguous United States, began erupting between the growing seasons of 1064 and 1065 A.D. Eruptions continued in … From Raton, it is a short 30-mile drive on highway 64/87 to Capulin. Sunset Crater, located about 25 km (15 mi) northeast of Flagstaff, Arizona, is one of the youngest scoria cones in the contiguous United States and is the youngest of about 600 such cones in the San Francisco Volcanic Field. We need you to answer this question! For many years, we believed that it erupted in 1064 and continued for 200 years – a very long time for a cinder cone volcano. People had been living in the area for at least several hundred years before the volcanoes erupted. When did Sunset Crater erupt? Sunset Crater, Arizona Location: 35.4N, 111.5W Elevation: 8,026 feet (2,447 m) Sunset Crater. Over the next 200 years, the heavier debris accumulated around the vent creating the 1,000-foot cone. A volcanic eruption started out slow, hinting to nearby settlers of the pending doom of the area. Sunset Crater is in the eastern part of the San Francisco volcanic field.

Not the ideal time to visit, but we did have the place almost to ourselves. More recent evidence indicates that the eruption began sometime between 1040 and 1100 and lasted, more typically, only a few months or years. As the rock-water soup reaches the surface of the earth, the water flashes into steam, causing the liquid rock to explode from the ground. The San Francisco Volcanic Field is a 4,700 square kilometers (1,800 square miles) area in the southern boundary of the Colorado Plateau.
“The Earth used to look just like that.” If you know the answer to this question, please register to join our limited beta program and start the conversation right now! 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. Sunset Crater and Lenox Crater Volcanoes were born in a series of eruptions sometime between 1040 and 1100. It stated “Cinder cones form when runny basalt magma is mixed with water beneath the ground.
Sunset Crater in northern Arizona is one of the youngest volcanoes in the USA. Unlike Meteor Crater, which formed suddenly and violently, Sunset Crater formed slowly and violently.
