I hope I'm sending the right message here. We're not looking at scale, we're just looking at albedo features.

I sketched the sketches without being able to tell what I was looking at (I couldn't even tell which end was North). It was only after I found a real-time Mars viewer and set it to the correct day and time (Mars rotates evert 24h37m, so a differnce of 2h in observing time can make a dramatic differnce in what you see) that I was able to match up my sketches with Martian features.
