ESA's Mars Ex­press space­craft im­aged a part of the Mar­tian high­lands south of the Valles Mariner­is val­ley sys­tem us­ing DLR’s High Res­o­lu­tion Stereo Cam­era (HRSC) dur­ing or­bit 23,232 on 23 May 2022. The im­ages and land­scape de­scrip­tions pre­sent­ed here are lo­cat­ed with­in the small rect­an­gle at the north­ern end of the im­age strip. The colour­ing of this to­po­graph­i­cal rep­re­sen­ta­tion shows how the Co­prates ridge sep­a­rates the vol­canic Thau­ma­sia plateau in the west from the Noachis Ter­ra plain al­most four thou­sand me­tres be­low, over a dis­tance of sev­er­al hun­dred kilo­me­tres. Pre­sum­ably, large mag­ma bub­bles from the in­te­ri­or of Mars caused the re­gion to arch up and re­sult­ed in tec­ton­ic stress­es and ex­ten­sion­al frac­tures. This is how the frac­ture struc­tures of the Nec­taris Fos­sae trench­es were formed.
