SP Crater - Cinder Cone
SP Crater is a cinder cone located about 25 miles north of Flagstaff, Arizona. It is one of many cinder cones in the San Francisco Peaks volcano field. It is about 800 feet tall and has a 400 foot deep crater. The last eruption is believed to be approximately 71,000 years ago.
A lava flow issued from the north side of the crater and can be seen in the images below. This is a basalt flow that is up to 100 feet in thickness with an aa surface. SP Crater is surrounded by many other older cinder cones which show their greater age as they are more deeply eroded.
