Sunflower is a nice girl's name... and is the state highpoint of Kansas.
You could name her after a style of climbing you enjoy, though names like "Crack", "Handjam", "Fingerlock", "Smear" or "Off width" might get a certain amount of teasing in grade school. "Free" on the other hand is not a bad name for a girl, though a bit reminiscent of the 60s.
