Idealized subglacial cavity network in plan view (A) and cross section (B). Unshaded areas are regions of ice-rock contact; shaded areas are regions of ice-rock separation (cavities). Flow directions in the cavities are indicated by arrows. Oriï¬ces are the most constricted parts of the cavity network and account for most of the energy losses. From Fountain and Walder, 1998, originally after Kamb, 1987.
