Toward the end of the afternoon, we continue our trip to Temimichat crater, following a 28 N-NE course on the line crosscutting both the Tenoumer crater and the center of the Richat structure.


Twenty kilometers from the goal we set out find, I finally realized that this hill I was seeing for the last 10 kilometers, was in fact the crater itself.


a month prior to our arrival saw a small lake in the crater.

Tenoumer crater

After leaving the small city of Ouadane, our off-road journey really starts. Our goal is to find Tenoumer crater situated 224 km distant on a heading of 28 N-NE. Satellites photos show the crater to be quite visible but our Russian maps, reputed to be the best for Saharan countries, leave much to be desired as to the locality of the Tenoumer crater. In this situation, with the GPS programmed on the crater, I am just driving, absorbing in the scenery and thinking of nothing in particular.
The energy necessary to create such a crater must have been tremendous. The energy released by the Hiroshima bomb paled by comparison! The crater's diameter is approximately 2 kilometers wide and the rim height is 100 m high. The asteroid would have to have had a diameter between 20 and 50 meters. This size doesn't seem like much, but with an impact speed approaching 70 km/s, the kinetic energy is colossal. Blocks of impact material weighing several tons were projected in all directions.
The bedrock has been transformed into lava. There is an abundance of shock metamorphic features everywhere in the granite rocks.
Toward the end of the afternoon, we continue our trip to Temimichat crater, following a 28 N-NE course on the line crosscutting both the Tenoumer crater and the center of the Richat structure.
