They are quite subtle but the tracks are visible from as far back as sol 310

Aah, thanks for finding those Alan.. I've been looking for the tracks around the time the Turkey pan was shot but without succes. They're very subtle indeed but that thin dark line could hardly be anything else.

This track-finding business is tricky! My first thought was - Spirit was never up on top of the ridge, the way alan shows it on Sol 310. It was in the valley just north of there. But the line is clear. I think that it's a small fracture in the rock. Then, looking out on the plains on the right side of the image, on an enlargement, narrow lines start to show up all over the place - canals on Mars, indeed. Some are probably tracks, but some can't be.

Here's my estimate of the actual route followed by Spirit. I think tracks are visible (covered up by my line, but check alan's version) where I indicate Sol 328.

We need some polar pans to get the exact locations!

I, too, find this an exercise like finding canals on Mars. I took the turning points from Phil's track and pasted them on Alan's version. For the life of me, I can't see the track that Phil identified while Alan's looks clearly visible.

The proof of the pudding will be in the polar pans.

If you look at the navcams from sol 310 it's pretty clear we were on a ridge rather than in a gully at the time.

Some positions near easily recognizable features, I expext Indian3000 will soon have more precise locations.

And some 360 navcam panoramas from two of those locations: sol 228 and 192. Can someone make these onto polars?

Alan, my apologies - you were right. The route map I plotted back in the old West Spur days was copied from the lower resolution route maps on the MER website. I didn't start looking at polars for location finding until later in the mission. You are right about the top of the ridge. This makes me want to go back and re-plot everything, which I was going to do anyway at a later date.

There are other lines off-track in many places though - we will still have to be careful deciding which tracks are visible.

Here is the route map as of sol 1041.

The current position is preliminary, based only on the rover's mobility data. I'll double-check it once the respective sol's 360º navcam panorama is downlinked.

Edited: Updated, based on these images.
