Plateaus are large fairly plat pieces of uplifted land surrounded by steep slopes. A landform can be identified as a plateau when the contour lines are quite close to each other all around while on the upper slopes there are no lines or hardly any lines signifying that the top is rather flat.
it is a contour line of elevation Control index contour, or just index contour
Contour lines that are evenly spaced and parallel indicate a plateau. The closer the contour lines are to each other, the steeper the terrain; the farther apart they are, the flatter the land. In the case of a plateau, contour lines would likely be spaced evenly and relatively close together, indicating a flat or gently sloping landform.

An Index Contour
An index contour is a thicker contour line that is labeled with the elevation of that contour. It usually appears every fifth contour line and helps to quickly identify elevation changes on a topographic map. Regular contour lines are thinner and connect points of equal elevation.
When a V-shaped contour line points downhill, it means that the contour line is under very low elevation. And incase your wondering about when the contour line is uphill, it means that the elevation level is very high.
The first contour line was created by Charles Hutton in 1771. He used contour lines to map a coal mine.
