What do the colors on the contour map of Johannesburg Mountain (2736m) mean?

The contour map uses a hypsometric color scale where green represents lower elevations, yellow and orange indicate mid-range altitudes, and white marks the highest zones near the summit. Thicker contour lines (index contours) are drawn at wider intervals to help you quickly estimate elevation.

What is the contour interval for Johannesburg Mountain (2736m)?

The contour map of Johannesburg Mountain (2736m) uses a 50m contour interval. This means each line represents a 50m change in elevation. Closely spaced contours indicate steeper terrain, while widely spaced contours show gentler slopes.

What does the elevation profile of Johannesburg Mountain (2736m) show?

The elevation profile is a cross-section through Johannesburg Mountain (2736m) from west to east, passing through the summit at 2,736m. It reveals the mountain's shape, steepness, and relative height compared to the surrounding terrain. The horizontal axis shows distance in kilometers from the peak.

Why does Johannesburg Mountain (2736m) have elongated ridges?

Johannesburg Mountain (2736m) was formed by tectonic folding, which compressed rock layers into long, parallel ridges. The contour map shows elongated lines that follow the axis of the fold, rather than circular patterns.
