Rock Canyon cinder cone and lava flow. Perhaps coeval with Dickinson Hill [24] and may also be the source of the 4.98 - 4.94 million years old Red Canyon flows. [37] Sidney Peaks basalt, probably of Pliocene age. [37] Blue Spring Mountain cone and lava flow, 2.78 million years old. [37] Horse Knoll cone and lava flows, 750,000 years old. [37]
The Kings Bowl and Wapi lava fields, both about 2,200 years old, are part of the National Preserve. This lava field is the largest of several large beds of lava that erupted from the 53-mile (85 km) south-east to north-west trending Great Rift volcanic zone, [10] a line of weakness in the Earth's crust.
