The landforms in this observation are quite diverse, with a segment of the Cerberus Fossae (a deep trough extending east-west) and surrounding terrain that has been eroded by some fluid, either water or lava.
There are many boulders in places, either on steep slopes or excavated by impact craters. The high hills are islands of older terrain surrounded by younger lavas.
Be sure to check out the stereo anaglyph.
This is a stereo pair with ESP_026712_1960.

Note: I have modified this title from "Landforms Near Grjotá Valles" to Landforms in "Cerberus Fossae." Grjotá Valles is some distance off to the east from the location in the above image. This site is actually in the heart of Cerberus Fossae, hence the title change.
