 Apart from a few geologists, only orienteers regularly use the English word "re-entrant" to describe a
landform.
On an orienteering map, a re-entrant appears as a U or V shape in the
contour lines, pointing back into a hillside rather than sticking out
of it (as would a spur). Physically, a re-entrant is a small valley,
the centre of which would collect water and funnel it downhill
if it were raining heavily. The segment of map shown here
includes several reentrants, three of which are circled. The west-most
one is a small, v-shaped reentrant, while the two eastern examples are
broad and somewhat shallower. |
