It is filled with lava flows for miles and miles over hundreds. Although the volcanic field hasn't had an actual eruption during the Holocene Era (which began 12,000 years ago and continues to this day), it's still very much considered an active volcano for its constant hydrothermal activity.

Jeean santiago Virtual Field Trips Mud Volcano Trail Yellowstone is one of the largest active volcanoes in the United States, it erupted 640,000 years ago. The most prominent landmark is San Francisco Mountain, a stratovolcano that rises to 3,850 m (12,633 ft) and serves as a scenic backdrop to the city of Flagstaff. A similar event could well have been involved at Mount Taylor volcano. (Credit: Brugger-Schorr, Carrie. The massive eroded Pleistocene stratovolcano is Arizona's highest peak. SAN FRANCISCO (CBS SF/AP) – California’s next ‘big one’ may not be an earthquake. The San Francisco Volcanic Field also includes several lava domes. the youngest of about 600 scoria cones in the San Francisco Volcanic Field and the only one active in the Holocene (1064-1067 A.D.). Covering 1,800 square miles (roughly 4,700 square kilometers), the volcanic field consists of volcanoes and lava flows, including SP Crater. Red Mountain is unusual in that its internal structure is exposed. Yup, the San Francisco Peaks are an extinct stratovolcano which last erupted some 200,000 years ago. Humphreys of the San Francisco peaks at 12,633 feet – and the state’s youngest volcano -Sunset Crater, which erupted less than 1,000 years ago and can be visited at Sunset Crater National Monument. Location of the San Francisco volcanic field in northern Arizona volcanic underpinnings are well exposed in the walls of the nearby Grand Canyon. Lava and other volcanic material appear purple, and the cinder cone field is tinged with green, as vegetation begins to colonize the newly laid landscape. The field contains 600 volcanoes ranging in age from nearly 6 million years old to less than 1,000 years (Miocene to Holocene), of which Sunset Crater is the youngest. Such a nice mountain city situated right in the midst of a potentially active volcanic field (SFVF). Over the past 6 million years, more than 600 volcanic cones formed, with an eruption every 3,000 years on average. Such an eruption is likely to be small and pose little hazard due to the remoteness of the area. They usually consist of clusters of 10 to 100 volcanoes such as cinder cones. miles and includes 600 cinder cones (the small pimple-like features), 10 silicic domes (e.g., Mt Elden, Kendrick Peak), and the San Francisco Mountain composite volcano - the largest volcano in the field, and at 12,666 feet above sea level, the highest point in Arizona. Sunset Crater, the State's youngest volcano, erupted in about A.D. 1085 and must have been witnessed by native inhabitants who lived very nearby. Red lines represent young Holocene-age faults. There are a number of potentially-active volcanic fields in Arizona, including the San Francisco Volcanic Field near Flagstaff. About 6 million years ago, volcanic activity began in the … The San Francisco field is situated near Flagstaff and was active as recently as 1085 CE, just 932 years ago with the eruption that formed Sunset Crater. The eruption produced three lava flows that cover ~8 km2, a scoria blanket up to 12 m thick covering an area of about 500 km2, and minor spatter cones and ramparts that marked the California.
