Title: Heegaard splittings with large subsurface distances
Abstract: (Joint work with Jesse Johnson and Yair Minsky.)

It is shown that sub-surfaces of a Heegaard surface for which the relative Hempel distance of the splitting is sufficiently high have to appear in any Heegaard surface of genus bounded by half that distance.
