As amazing a place Mars as is the uniformitarian claims of form JPL on Martian geology are shown wrong because evidence show that it has a clearly catastrophic nature. Mars’ largest impact basin called
Another smaller impact basin called Argyre seems to have been responsible for ripping open Valles Marineris. In fact the dominant distribution of craters on Mars suggests that they came largely from the same direction suggesting a short period nearly unidirectional bombardment rather than a longer period of occasional random impacts.
This shows that Martian geology has a largely catastrophic make up and not a uniformitarian one.
