Sol 3819, October 21, 2014. Exploring in the Ulysses Crater ejecta field on Wdowiak Ridge, the rover team is currently studying a roundish rock dubbed Birmingham and a target area on it named Crimson Tide. Birmingham, about half a meter wide, appears to be igneous with layering or planes within the rock. (Planetary scientist Tom Wdowiak, for whom the ridge is named, was at the University of Alabama.)
