Description
This photograph from northwestern New Mexico shows a ridge roughly 30 feet (about 10 meters) tall that formed from lava filling an underground fracture then resisting erosion better than the material around it did.
The dike extends from a volcanic peak (out of view here) called Shiprock in English and Tsé Bit'a'í, meaning "rock with wings," in the Navajo language. It offers an Earth analog for some larger hardened-lava walls on Mars, shown at PIA21264.
