What do the colors on the contour map of Mount Sidley (4285m) 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 Sidley (4285m)?

The contour map of Mount Sidley (4285m) 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 Sidley (4285m) show?

The elevation profile is a cross-section through Mount Sidley (4285m) from west to east, passing through the summit at 4,285m. 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 Sidley (4285m)?

At Mount Sidley (4285m)'s latitude (77°), the estimated permanent snow line is approximately 300m. Since Mount Sidley (4285m) reaches 4,285m, about 3,985m of the mountain extends above the snow line. This is shown as a dashed blue line on the elevation profile.

Why does Mount Sidley (4285m) have gentle slopes?

Mount Sidley (4285m) is a shield volcano, built almost entirely from fluid lava flows. The contour map shows widely spaced lines, reflecting slopes that rarely exceed 5–10 degrees — much gentler than a stratovolcano.

The topographic contour map of Mount Sidley (4285m) shows widely spaced, gently curving contours reflecting broad, low-angle slopes. Contour lines are drawn at 100m intervals, with index contours (thicker lines) every 500m. The hypsometric color scale ranges from green (lower elevations) through yellow and orange to white (highest elevations near the 4,285m summit). Above 300m, the estimated snow line at this latitude, contours transition to cooler tones indicating permanent snow and ice.
