A saddle, or col, on a topographic map appears as

  • A.a fan of contours below a cliff
  • B.a break in the contour pattern
  • C.a low point between two summits
  • D.a single closed contour on a ridge

Answer: C

Correct answer: a low point between two summits

A col shows as an hourglass: contours closing around a summit on either side, with the pattern pinching in between them where the ground dips. It is the lowest point on the ridge joining the two summits and the highest point on the line crossing from one valley to the other, which is why passes and routes go through it.
