Summary
The original finding aid described this as:
Description: Infrared Earth observation image of the Yirrigue Volcanic Caldera Complex, Tibesti Mountains, Chad taken during the STS-37 mission from Atlantis, Orbiter Vehicle (OV) 104. Familiarly referred to as the squid because of its suggestive shape, the Yirrigue Volcanic Caldera complex is one of the nine major volcanic centers in the Tibesti Mountains of northern Chad. Dark colored lava flows radiate from the younger volcanic cone, Tousside. Older rock units are heavily eroded by streams that flowed when rainfall was more common in the Sahara.
