What is the minimum aperture needed to see surface detail on Mars?

For a telescope, you can probably see Syrtis Major (the most prominent
albedo feature on Mars) with a 60 mm telescope. But I'd say that you'd
want at least 100 mm (4 inches) to see interesting detail on Mars, and
6-8 inches unless you're an experienced planetary observer.
