1. A hole in the roof of a cave passage that may be either a rather large blind roof pocket or a tributary inlet shaft into the cave system. A feature described as an aven when seen from below may equally be described as shaft when seen from above, and the naming of such a feature commonly depends purely upon the direction of exploration. Many avens close upwards to impenetrable fissures but may still be important hydrological routes; few caves are without them. In parts of France, aven is equivalent to the British term, pothole [9].
   2. (French.) A vertical or highly inclined shaft in limestone, extending upward from a cave passage, generally to the surface; smaller than an abîme. Commonly related to enlarged vertical joints.
   Compare cenote; natural well; pothole.
   3. (British.) A vertical extension from a shaft in a passage or chamber roof that tapers upward rather like a very elongate cone [10].
   Compare dome pit. average interstitial velocity
