S P Crater is a cinder cone volcano in the San Francisco volcanic field, 25 miles (40 km) north of Flagstaff, Arizona, United States. [4] It is surrounded by several other cinder cones which are older and more eroded. It is a striking feature on the local landscape, with a well-defined lava flow that extends for 4.3 miles (7 km) to the north. [5]
The Sunset Crater eruption peaked at VEI 4 (Sub-Plinian), produced a total 0.52 km 3 of ejecta, [9] had an eruption column between 20-30km tall [10] and produced a blanket of ash and lapilli covering an area of more than 2,100 square kilometers (810 sq mi), which forced the temporary abandonment of settlements of the local Sinagua people.
The volcano was the site of the Mount Pisgah Volcanic Cinders Mine, a cinder quarry that produced pumice for commercial use, the primary end product being railroad ballast for the Santa Fe Railroad. The mountain is currently owned by Can-Cal Resources Limited, a Canadian company specializing in exploration of precious minerals in California. [4 ...
The most famous cinder cone, Paricutin, grew out of a corn field in Mexico in 1943 from a new vent. [3] Eruptions continued for nine years, built the cone to a height of 424 meters (1,391 ft), and produced lava flows that covered 25 km 2 (9.7 sq mi). [3] The Earth's most historically active cinder cone is Cerro Negro in Nicaragua. [3]

The Cinders are part of the Black Rock Desert volcanic field. The lava of The Cinders is basalt of late Holocene age. The basalt erupted from the vent at the Ice Springs craters less than 700 years ago (as of 2020). [2] It is the youngest basalt flow in Utah. To the south is a somewhat older lava flow surrounding Tabernacle Hill.
