American Geophysical Union honors two Departmental faculty. Richard Walker is the 2019 Hess Medalist and James Farquhar has been named an AGU Fellow.

Sisters Louise Lovell and Florence Mills donate a piece of the Canyon Diablo iron meteorite to the Department (with Chair Richard Walker accepting), making it the first meteorite specimen in our collection.

Professor (and current Chair) of Geology has been awarded the title of Distinguished University Professor.

New Study Identifies Causes of Multidecadal Climate Changes - Team including Professor Michael Evans contributes to analysis that suggests current climate models can accurately predict climate warming several decades into the future.

UMd team led by Nick Schmerr awarded one of eight NAASA Solar System Exploration Research Virtual Institute (SSERVI) grants
