The top 2 maps here show different versions of traverses in this area. Both landing sites are close to Penticton crater. At Penticton (bottom image) the crew would drill down into the supposed aquifer at the top of the slope, descend on a tether to the gulley itself and visit the deposit below the gulley. It's not really certain that this activity indicates water flow, it might be a dry debris flow, but water is very enticing.

A candidate HEM-SAG landing site at Centauri Montes, east of the Hellas impact basin. 3 maps illustrate the site. The top two maps show different versions of the traverses to be followed and both would land near a small crater called Penticton. The bottom map shows Penticton with activities near it. The crew would stop at the top of the crater rim above a small gulley, thought to show evidence of water flow. They would drill down to the supposed aquifer, and might descend the slope to the gulley itself, on tethers. They would also enter the crater and visit the debris flow below the gulley.

The last HEM-SAG site I will look at is at Centauri Montes, east of Hellas, a giant impact basin. Glacier-like flows around some mountains here suggest ice is present, and a crater called Penticton has gullies on its walls. Mars Global Surveyor images taken in 1999 and 2005 showed a change in one gully (a bright deposit below it), suggesting possible active water flow:

... and then drive off the polar cap to meet up with a pre-landed return vehicle. These missions are not like Apollo, they are on a very different scale. The HEM-SAG report did not cover this but Jim Garvin had a poster at LPSC in 2008 with details reproduced in my map. During the drive south, more geophysics stations could be set up. The light-toned area should be white but my fake colour scheme doesn't know that. Tomorrow we'll look at our last HEM-SAG site.
-SAG

A HEM-SAG mission to the north polar ice cap would study climate history by drilling into the cap. These details are from a 2008 LPSC poster by Jim Garvin. Drilling and setting up a geophysical network would take 220 sols. Then the crew would drive south to avoid the north polar night, setting up more geophysics stations, and eventually meeting their return vehicle.

HEM-SAG also wanted to look at climate history by drilling into a polar cap to study layers of ice and dust. This brought unique problems. The other 3 HEM-SAG missions would spend 500 days on Mars, but with the poles only sunlit for half a year you would have to either land or depart in darkness. Except - remember Wernher von Braun's Mars Project? Land on the pole, then drive off it. This new mission would land in daylight, do a deep drill and other studies for 220 sols ...

These three sites - old, middle and young, Jezero, Arsia and Mangala, would be the first three sites visited by crews on Mars. They made up the reference mission sequence which would be the first phase of human exploration of Mars. I have been showing 'missions which didn't happen' but we should really call this set 'missions which haven't happened yet'. Will actual human missions go to these places? We don't know, but they are not Musk colony sites.

I have to correct myself - the Mangala Valles sites was in the youngest period of Mars history, the Amazonian. I have edited yesterday's post but wanted to point it out here. The middle period of Mars history, the Hesperian, was studied at Arsia Mons in Tharsis, seen here. The landing site is west of the mountain in an area of lava lows and glacial deposits. One study suggested they might be carbon dioxide glaciers.

A landing site from the HEM-SAG study at Arsia Mons in Tharsis. The site is west of the giant volcanic mountain and traverses run out from it to visit glacial features as well as lava flows.
