Santa María Rupes is a prominent lobate escarpment and fault line on Mercury.

[2][3] According to data from Arecibo, it has a relief of roughly 700m.

[4][3] The formation was named after the ship Santa María, used by Christopher Columbus.

[5][6] The escarpment was probably created as Mercury cooled and thus contracted.
