What do the colors on the contour map of Mount Lyell (3997m) 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 Lyell (3997m)?

The contour map of Mount Lyell (3997m) uses a 100m contour interval. This means each line represents a 100m change in elevation. Closely spaced contours indicate steeper terrain, while widely spaced contours show gentler slopes.

What does the elevation profile of Mount Lyell (3997m) show?

The elevation profile is a cross-section through Mount Lyell (3997m) from west to east, passing through the summit at 3,997m. 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.

What is the snow line on Mount Lyell (3997m)?

At Mount Lyell (3997m)'s latitude (38°), the estimated permanent snow line is approximately 3,800m. Since Mount Lyell (3997m) reaches 3,997m, about 197m of the mountain extends above the snow line. This is shown as a dashed blue line on the elevation profile.
