#MarsWalk Day 78, 445.2 km

Today I logged a sluggish 1.2 km. Worked from home, didn’t go for a walk, didn’t do anything involving much walking. The whole week was below average distance.

But I’ve crossed Hrad Vallis. This is a channel, 825 km long, whose name derives from the Armenian name for Mars.

It may have been created by water, created from ice that melted due to magma associated with the volcano Elysium Mons. On the other hand this paper proposes it might have been cut by low viscosity lava flows.

My path this week started near the upper edge, left of center, of this MRO Context Camera image and went almost due south almost to the bottom edge, crossing the channel on Tuesday close to where those two prominent craters are.
