What do the colors on the contour map of Mount Sefton (3151m) 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 Mount Sefton (3151m)?

The contour map of Mount Sefton (3151m) 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 Mount Sefton (3151m) show?

The elevation profile is a cross-section through Mount Sefton (3151m) from west to east, passing through the summit at 3,151m. 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 Mount Sefton (3151m) have elongated ridges?

Mount Sefton (3151m) 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.
