Document Summary
Difficult to distinguish lava channels from water-carved channels. Olympica fossae appears sinuous in some places and rectilinear in others -- combination of te(cid:272)to(cid:374)i(cid:272) a(cid:374)d flu(cid:448)ial pro(cid:272)esses (cid:373)ay (cid:271)e highest outflo(cid:449) (cid:272)ha(cid:374)(cid:374)els o(cid:374) mars. Channels emerge from graben just to the east of olympus mons. Several large channels extend from southern highlands into amazonis and elysium planitiae. Largest outflow channel in this region is mangala vallis. Starts from a notch carved into a graben. Like circum-chryse channels, contains streamlined islands and sourced ground. Some of the youngest outflow channels on mars start at graben (cerberus fossae) in this region. Athabasca vallis is a large, young, channel that flows from cerberus. Channels flows southwest where it is buried by plains lavas. Grjota vallis also starts at a graben and flows ~400km east before being lost in the tartarus. Marte vallis starts in the cerberus plains and flows up to 20 n. it is eventually lost in.
