I strongly suggest Larry Niven for weird habitable and yet hard-science worlds.

Apart from the aforementioned Canyon, you have:

Jinx: Can't even describe adequately here in the forum, suffice to say- Only habitable in two bands to the "north" and "south" of the equator, and not the polar regions (They're in 'vacuum'). http://en.wikipedia.org/wiki/Jinx_(Known_Space)

Plateau - Venus-like, with a plateau (called Mount Lookitthat), half the size of California, rising high enough out of the dense atmosphere to be habitable.

We Made It - The planet's axis is pointed along the plane of its ecliptic (like Uranus), creating ferocious winds on the order of 500 mph (800 km/h) during half of the planet's year, forcing the people to live underground.

Those are just the high points for weather. Definitely check out: http://en.wikipedia.org/wiki/Known_Space and look under "Locations".
