Summary: This is an expository paper, aimed at giving a leisurely account of some model geometries associated to surface Kleinian groups. We describe the notion of manifolds of amalgamation geometry and its generalization, split geometry. We show that the limit set of any surface group of split geometry is locally connected, by constructing a natural Cannon-Thurston map.
