Crazy Little Sister is basically two teetering blocks that are leaning against each other - not really a tower. The climb is, well, not really a climb either, more of an easy boulder problem.

The crux of the route is getting there, which involves lots of scrambling up and over blocks until WELL North of Sister Superior. If you go the wrong way it's worth it to turn around as the scree is very loose in many places (in search of a shortcut I jumped to a desk-sized rock which began sliding down the steep slopes and over a cliff band - I jumped off just in time and only by spread eagling on the ground could I stop from sliding down with it). I recommend going around the far (east) side of Sister Superior for as long as possible.

Without the photo in Bjornstad's guide I would have never found this rock, but once you see it you can't miss it - there is a hole in the middle where the two blocks rest against each other and it really does look like it's going to fall over. Stem your way up, do an easy mantle, snap the photo and downclimb it.

No anchors on the top - some gear available on the way up I suppose.
