Learn the skill

Elevation is height relative to a specified reference level, or datum. To find a height difference, subtract the lower elevation from the higher when both use the same datum. These terrain records are invented.

Worked example

Two sites are 120 m and 180 m above the same datum. Their elevation difference is 60 m.

Three schematic nested elevation contours are labeled 120, 150 and 180 meters using one datum. The difference between 180 and 120 is 60 meters; that is not the trail distance.
