Slide3The famous “Face on Mars”
Slide4Now don’t get all excited…
Slide5How Come We Missed These?
Slide6Look harder!
The Panda!
George Washington Screaming!
Slide7Kermit the Frog!
Slide8Surface Water Flow Features
Geological features suggest that at some point water must have flowed on the surface of Mars
Why? Look like water features on Earth!
Characterized by…
Dendritic
vs.
Anastomosing
Drainage
Fast Formation vs. Slow Formation
Slide9Dendritic Patterns
Dry Riverbed on Mars
River in Yemen
Slide10Anastomosing:
Branching and then Reconnecting
Slide11Islands in Anastomized Streams
Slide12Fast vs. Slow Formation
Anastomosing
drainage usually the result of a flood event
Dendritic
drainage usually caused by erosion over time
So… Which forms more “quickly”
Note that there is some wriggle room in geomorphology… It does what it wants.
Slide13What Are We Doing Today?
Characterizing some features on Mars
Figuring out how much water must have flowed to create features using a
lil
’
guesstimation
Figuring out how old features are (CRATER COUNTING!)
