What do the colors on the contour map of Nantai-san (2486m) 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 Nantai-san (2486m)?

The contour map of Nantai-san (2486m) 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 Nantai-san (2486m) show?

The elevation profile is a cross-section through Nantai-san (2486m) from west to east, passing through the summit at 2,486m. 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 Nantai-san (2486m) have a crater?

As a stratovolcano, Nantai-san (2486m) was built by alternating layers of lava and ash. The summit crater is visible on the contour map as a small depression within the tightly spaced concentric contours near the peak.
