Craters of the Moon National Monument & Preserve, ID (No. 3)

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, a line of weakness in the Earth's crust. Together with fields from other fissures they make up the Lava Beds of Idaho, which in turn are in the much larger Snake River Plain volcanic province. The Great Rift extends across almost the entire Snake River Plain.

Elevation at the visitor center is 5,910 feet (1,800 m) above sea level.

Total average precipitation in the Craters of the Moon area is between 15–20 inches (380–510 mm) per year. Most of this is lost in cracks in the basalt, only to emerge later in springs and seeps in the walls of the Snake River Canyon. Older lava fields on the plain support drought-resistant plants such as sagebrush, while younger fields, such as Craters of the Moon, only have a seasonal and very sparse cover of vegetation. When viewed from a distance, this cover disappears almost entirely, giving an impression of utter black desolation. Repeated lava flows over the last 15,000 years have raised the land surface enough to expose it to the prevailing southwesterly winds, which help to keep the area dry. Together these conditions make life on the lava field difficult.

Some of the lava flows I’ve recorded seem to defy physics when you see them move. Evidently, they do not but the way they flow, interact & clash is sometimes so bizarre. #iceland
