Well... here's my contribution...
I've always been searching for that perfect sidewinder track and can't seem to get what I'm looking for.
This is Anza Borrego, CA.
Lizard tracks.
These are Algadones Sand Dunes, CA.
Lizard tracks from Algadones.
This is a cool implied track. I though it was so interesting that the odds of it happening and then me finding it... When your time is up... you really have no say.

These squirrels were running all over this particulat wash. You can pretty much see this guys trajectory.
Tortoises are my main interest so...
This is outside of Glamis, CA.

In this particular wash I've found the tracks of 7 different tortoises on one occurance but I didn't have my camera. I've never seen a tortoise there... only tracks.
This final set is Gopher tortoises.

It had just rained a little to only cover the surface leaving these really pronounced tracks.

Then there were these Ghost crab trails.
Hope you enjoyed it.
