The Uinkaret field, perched on the north rim of Grand Canyon, also evinces volcanic activity as recently as about 1,000 years ago. This relatively young age and the slow activity in the volcanic field means it is still considered active with future eruptions expected in the next few thousand years from new vents. Innerhalb von fünf bis zehn Jahren wurden Gebiete unterhalb des Sunset Craters, die nur von einer dünnen, fruchtbaren Ascheschicht bedeckt worden waren, wiederbesiedelt, und es entstanden dort große, prosperierende Siedlungen, darunter die des Wupatki National Monument.

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 … When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is lost. Vor Beginn der Eruptionen 1085–1090 war die Gegend um den Sunset Crater dicht besiedelt (→ Sinagua-Kultur). These “corn rocks” are believed to have been made when people placed ears of corn near hornitos, spattering vents that form above lava flows or tubes. Volcanoes can have more than one vent.
