Alluvial Fans on Mars

Posted on Mon, May 2, 2016

Alluvial fans are semi-conical landforms that consist of sediment deposited by a stream where it emerges from a rugged mountain front onto an adjacent, relatively flatter land. During infrequent, strong rain storms or snowmelt events, sediments deposited by streams gradually build up fan-shaped deposits. Alluvial fans on Earth and Mars are important because they contain clues about past climate conditions.

Dr. John Grant and Sharon Wilson spoke to International Innovation about their innovative research into Martian climate history and geology.
