Yogi Rock

Yogi Rock is a rock on Mars that was discovered during the Mars Pathfinder mission in 1997, and named by Geoffrey A. Landis. The rocks found on the mission were named after famous icons and figures, and Yogi Rock was thought to resemble the head of a bear looking away from the spacecraft. It was, appropriately, then named for the famed cartoon character Yogi Bear.

The rock was the first on Mars found to be made of basalt, which suggests previous volcanic activity in the region as basalt is an igneous rock. The smoothness of the surface also suggested the past existence of water in the region. Yogi was also the first large rock reached by the Sojourner rover and was analyzed by an X-ray spectrometer to determine its composition. In a notable coincidence, the rock under the Yogi Berra stadium also turned out to be basalt.
