Peter researched geological structures of the Hesperia Plain regions and the Valles Marineris. Other Scientists joined in with their own professional perspectives.
Peter could not hide his interest in the Valles Marineris (The Grand Canyon of Mars) Even colours of deposits give clues to chemical composition, and being a very deep depression it's closer to Mars' centre with a slightly thicker atmosphere too, with water trapped in ice. The essence of life.
Here's the Wiki Scientific description Craig which I found interesting:
Just skimming it even. Apparently it's a major feature of Mars' geology!
Dimensions: Valles Marineris is the largest canyon system in the solar system, stretching over 4,000 km (2,500 miles) across the Martian equator. It is up to 200 km wide and reaches depths of up to 7–11 km (roughly 4–7 miles).
Formation: It is not a river-carved canyon like Earth's Grand Canyon; rather, it is a massive tectonic rift that widened over time. It likely formed as the crust thickened and buckled under the weight of the nearby Tharsis volcanic region to the west.
Regions:
Noctis Labyrinthus: Located on the western edge, it is a jumbled, heavily fractured terrain with high, massive blocks.
Chasmata (Ius, Melas, Candor, Coprates): A central series of deep, interconnected canyons that contain thick layered sediments (possibly volcanic ash or ancient lake beds).
Outflow Channels: The eastern end of the canyon empties into the northern plains of Chryse Planitia, suggesting it served as a channel for massive floods.
Features: It contains steep walls, massive landslide deposits, and potentially glacial ice at its base.

Hesperia Planum (Hesperia Plain)
Location: A vast upland plain located to the northeast of the Hellas impact basin, serving as the type region for the Hesperian Period.
Geological Character: It is characterized by extensive, flat, lava-filled plains, with volcanic deposits that are up to a few hundreds of meters thick.
Ridges: The region is covered with small "wrinkle ridges" formed by the compression of volcanic plains as the planet cooled.
Volcanic Origin: The lavas were likely derived from nearby volcanic centers, including Hadriaca Patera and Tyrrhena Patera.
Hydrology: The Hesperia region is associated with the early stages of catastrophic flooding on Mars, with large outflow channels—such as Reull Vallis, Dao, Niger, and Harmakhis Valles—originating from or passing through it.

Connection: Hesperian Activity
The Hesperia Planum and Valles Marineris are linked by the massive geological activity of the Hesperian epoch. As the Tharsis volcanoes grew to the west, the resulting stresses caused tectonic rifting (Valles Marineris) and massive volcanic eruptions (Hesperia Planum). These events also caused large-scale melting of subsurface ice, leading to catastrophic floods that carved the outflow channels seen in both regions.

Wellham: So Peter what is yours and our colleagues, Pederson and Webkes hypothesis on Valles Marineris . Could it harbor underground Martians. Also is there a chance of their being an under ground lake which would certainly sustain life.Peter researched geological structures of the Hesperia Plain regions and the Valles Marineris.

Meanwhile back at the lower Planitias an under ground invasion was under way with Wallace and O'Donnell leading their respective special forces into the bowels of Mars. The breathing apparatus was no longer needed once the large metal doors were closed which meant the troops could carry more weaponry. By 500 mts no Martians had been discovered which meant they had the element of surprise. But not for long....
